The xo-3 solves many problems of
the conventional “hybrid”: Its “ARC”
bars position your wrists more inward, for
better climbing and sprinting, and an extra
hand position. The top-mount shifters are
easier to use than underbar shifters; and the
round chainrings promote smooth pedaling.

The 2.2 Perce Solution
THIS YEAR CLOSE TO TEN MILLION BIKES WILL BE SOLD IN THE UNITED States. Of those, about
2% million will be sold by independent bike dealers; the rest, by mass merchandisers. There are 7,000
independent bike dealers in the United States; fewer than 400, or 5.7 percent of those dealers sell
Brivcestones. That’s eight per state, average. Of the 2% million bikes sold by those 7,000
dealerships, just 55,000—or 2.2 percent—are BripcesTones. We have 29 competitors. So in the big
picture (the total U.S. bike market), we're microscopic; and in our 30-team league, we're merely
small. This has advantages.
For example, our small size allows us to be
really. particular about our bikes. We're large
enough to matter to component makers (and it
probably doesn’t hurt that our parent company,
BripGEestone Cycie Co., Lrp., Tokyo, is
Japan’s largest bicycle manufacturer); but we're
small enough so that our demand
requirements are unlikely to exceed
our suppliers’ capacity—a situation
that would certainly lead to compro-
mising our specifications.
Though this next pronounce-
ment may border on elitism or snob-
_ bery, we offer it simply as fact: We
don’t aspire to sell any of our bikes to
a “typical bike buyer,” and our lineup does not
include “something for everyone.” Here again,
our small size allows us to choose the trends we
want to pursue, to disregard the ones we disdain,
and to be different when doing so will make a
better bike. Having to sell only 1,500 of a par-
ticular model, for instance, gives us the latitude
to make it special.
But this is not to say that BripGEsTONE
bikes have limited appeal. We’ve been accused
many times of going our own way, but in all
instances it’s been for practical reasons that,
more often than not, were ahead of their time.
In the arena of production mountain bikes,
for example, the list of BripcEsTone “firsts”
includes two-finger brake levers, sub-17-inch
chainstays, 73/71-degree geometry, toe clips,
narrow handlebars, and racing saddles—all of
which have since become “industry standards.”
Likewise, we carried the torch for round
chainrings, top-mount shifters, and cantilever
brakes, even when it was not popular to do so.
These examples are not rare, isolated, and
carefully selected—they are typical. When we
take a minority stance on a technical
issue, we do so for sensible reasons.
BRIDGESTONES are, if anything,
sensible. We don’t claim to sell ex-
citement or a lifestyle. Excitement,
as you well know, comes from riding;
and your purchases shouldn't define
your lifestyle.
A further benefit to our small
size is that it gives us the freedom to select our
dealers carefully. It’s not our policy to give our
sales representatives quotas for opening new
dealerships. Rather, they have both the freedom
and the luxury of seeking out the best dealers
in any area, which is one reason why the quality
of BripcesTone dealerships exceeds, by a
good margin, the industry average. (Two years
ago more than 375 dealers applied for
BRIDGESTONE dealerships; we selected 40.)
The drawback to having so few dealers is that
it’s quite possible you'll have to leave town to
find one.
We've seen to it that these bikes are worth
the trip. Each ofour new models earned its place
in our lineup, and compared with other bikes in
their use-category, each is without peer. Small
as we are, we beat the giants. And all others.

How Our Bikes Are Spec’d
MOsT PEOPLE ASSUME spec’ing bikes requires
bike smarts and creativity. It doesn’t. Bikes are
spec’d mostly by ricochet, default, and stub-
bornness. Here’s how it works.
DECEMBER-JANUARY: RUMORS AND CRUDE PROTOTYPES
We hear rumors about the new parts in Decem-
ber, and those rumors are confirmed or proved
wrong in January, when we get faxes and visits
from parts makers. Then we see crude proto-
types, often handmade from wood or clay and
usually labeled “no test,” meaning “fondle gen-
tly, please.” Sometimes the prototypes are
modified existing parts, in which case we can
ride them around our parking lot. The produc-
tion parts don’t yet exist.
EARLY FEBRUARY: RESERVING PRODUCTION TIME AND REVIEW
If we haven't reserved production time in the
factories, we do so now. Then we review the
current models, talk with our sales reps, review
dealer comments, and decide what changes, if
any, we should make.
LATE FEBRUARY-EARLY APRIL: SPEC ING THE BIKES
We start out idealistic, ruling out nonround
chainrings, painted cranks, and cranks with
high Q-Factors. After reality sets in, it becomes
clear where we have to compromise. The more
costly the bike, the less often we compromise.
We find out what’s really available, as op-
posed to what just happens to be on the parts
makers’ menus. Parts makers generally prefer
not to make a part unless they get lots of orders
for it; and if we’re the only ones who order it,
they may impose inconvenient ordering policies
and delivery schedules, to guide us towards the
same part everyone else is ordering. If we want
the part badly enough, and we generally do, we
put up with the restrictions.
Special parts made just for us are another
story. Our success depends on timing (handle-
bars require less time than cranks) and our
relationship with the maker. We generally bat
about .650 in this game, but our strikeouts this
year included cheaper bar-end shifters; bar-ends
compatible with 16mm inside-bar diameters;
low-priced, low-Q_cranks; and, lastly, a left
(front) top-mount shifter that downshifts on
the forward stroke. Maybe next year.
THE E FACTOR
When the specs are 98 percent final, we review
them looking for a reason or excuse someone
might give for not buying a particular model.
Usually it’s something unusual about the bike.
Examples this year include bar-end shifters on
the RB-I and the Moustache Handlebars on our
XO-1 and XO-2. Any obvious, unusual spec
requires more explaining and scares off timid
customers. For this reason, we call these bikes
“high-e£ bikes,” and we seriously consider
whether the functional advantage is worth the
marketing risk. Usually it is, and our “high-r
bikes” are the ones we’re most proud of.
Everything about spec’ing encourages us to
conform. Spec'ing bikes is like painting by num-
ber: There seem to be many choices, but on
closer inspection you discover your limitations.
Sometimes getting the bike to turn out the way
you want it to means making up your own rules
and hoping you can pull them off; but time
restrictions and practicality often don’t allow
that, and our “first choice” is sometimes the least
of several evils. Fortunately, many modern bike
components work pretty well.

How To Buy A Bike
E> SHOP FOR A DEALER, NOT A BIKE “2
Manufacturers design and spec the bikes and pick the materials, then
depend on dealers to assemble this mass of potential into a high-
quality, trouble-free bike. Bikes are unique in this way; the quality of
the ready-to-buy bike of any given model varies from dealer to dealer.
The best advice we can give you is to find a dealer you like and trust
and who has a good reputation.

PAY A LITTLE MORE
The best dealers take
the time to assemble and

and charge you for it.

poorly assembled, heavily
discounted bikes.

the sequel.
Es” 4 WORD ABOUT PRICES a
Up. Last year you could geta decent, modern, moderately lightweight,
multi-speed bike for $300. In a’92 model the same $300 buys you an
exercise in cost-down materials and manufacturing methods; a hollow
image high on frills and features, low in quality. Such a bike is fine for
basic utility rides and short commutes—and these are noble, legiti-
mate uses indeed—but it’s probably overgadgetized for these pur-
poses, and in any case itis not suited to hard, long-term, athletic riding.
The least expensive 1992 BRIDGESTONES, our BB-I and X0-3,
typically cost between $380 and $400. We have some leftover CB-1’s
from last year, and they can be had for less. These are good bicycles.

Getting Sized and Fitted
Your correct frame size depends on the kind of bike, how and where
youll ride it, and even, to an extent, your culture. For instance, the
Pennsylvania Dutch ride bikes that most of us would consider to be
two to three inches too big; yet they've adapted to these “too big” bikes,
and find them perfect for their big-gear, slow-cadence riding style.
Most riders, however, prefer smaller frames.
FOOLPROOF FRAME-SIZING
Wearing cycling shoes or normal shoes-something other than heels—
straddle the top tube with your feet 12” apart.
CS* On a mountain bike, your crotch should
clear the top tube by 3 to 4”.
C3" Ona road bike it should clear byrto 2%".
ES” On a bike that’s neither a mountain or a
road bike, size it somewhere in between.
Generally, more athletic riding and rougher
terrain require more clearance—for example,
4" ona mountain bike and 244" ona road bike.
There’s a movement toward really undersized mountain bike frames
with extra, extra long seat posts and stems. This stresses the frame
unnecessarily and changes the bike’s handling.
SIZING STEMS, HANDLEBARS, AND CRANKS
c= Longer legs need longer cranks.
cs Longer arms and torsos need longer stems.
ES> Broader shoulders need wider (drop-style) handlebars.
We match all these things to the frame size, so a box-stock
BripcESTONE will most likely fit you pretty well. (For specific crank
lengths, stem lengths, etc., on any given model and size, please refer
to page 47.) Finally, if you want to change anything from the stock part,
keep in mind that this is labor-intensive. Changing a stem length, for
instance, means unwrapping the handlebars, trashing the tape, and
undoing the brake and derailleur adjustments—which can easily take
up to half an hour. Don’t hesitate to change these details if they aren't
perfect, but be willing to pay for it.

Manners for Off Roacles
a
DON’T RIDE IN MUD.
IF YOU MUST RIDE IN MUD,
don’t ride in clay-based mud, which sticks
to your tires and makes riding impossible
anyway. You wreak the most trail
damage on this type of mud.
<=
IF YOU HAVE TO RIDE IN CLAY-BASED MUD,
use tires from 1.25 to 1.4" with little or no
tread. We ride Specialized Fat Boy™, Tioga
City Slicker™, Tom’s Slick, and Specialized
Nimbus™—and they all work better than big,
fat knobbies because they don’t attract as
much mud, and they’re easy to wipe off.
&
DON’T SKID.
If you cannot descend without skidding, walk.
If you can’t corner without skidding, slow
down. If you can’t slow down...
=
BE QUIET.
Whoops and yelps and howls make you
sound drunk, drugged, rowdy, threatening—
or all four at once.
BE KIND TO ANIMALS.
Carry your bike past horses unless the rider
tells you it’s okay to ride. Don’t let the
freewheel click—some horses mistake a
clicking freewheel for a rattlesnake.
Don’t scare cows, because scared cows run
and are likely to trip.

WEAR COLORS COMMON IN NATURE.
Neons are fine for visibility in traffic,
during deer season, and for beachwear, but
they look out of place in the country.
The idea is to minimize your impact
not only after you've left, but also
while you're riding. Bike magazine cover
boys and cover girls are not good
role models in this regard.

Top-Mount Mnillers Vs. Underbar Shifters
SIMPLE, MINIMAL, RELIABLE
WEIGHT
Top-mounts weigh two to five ounces less than
underbar shifters.
VERSATILITY
Top-mounts have a friction option and in the
friction mode they work with any chain, free-
wheel, freehub, cable, and cable housing regard-
less of brand or country-of-origin.
Most underbar shifters don’t have a friction
option, so they work only with a narrow range of
the same company’s drivetrain components.
FUNCTION
Since top-mounts have only one shifter per side,
not two, they are less confusing. It’s easier to
shift top-mounts with the heel of your hand—
a benefit you'll appreciate when your fingers are
cold and stiff or when
you're wearing mittens.
PRACTICALITY
When underbar shifters
are built into the brake
lever, you can’t position
them independently, and
if you crash and break
either of them—or simply
wish to upgrade—you
must replace both. Since
having a one-piece
shifter /brake lever com-
bination offers no func-
tional advantage, we pre-
fer keeping them separate.
AVAILABILITY
Underbar shifters are available ina wide range of
prices and qualities, but top-mounts are scarce
in the price and quality ranges appropriate for
$350 to $600 bikes. This forces manufacturers
who would like to spec top-mounts either to
severely upspec or severely downspec, and is one
reason there are so few top-mount shifters on
bikes in this price range.
DSE~ Pro racers who are paid to use equipment
will no doubt win a lot of races this year with
underbar shifters, and you can read their testi-
monials in advertisements. It’s possible that
some racers prefer underbar shifters, but others
use them as part of their promotional duties.
Personally, we prefer top-mounts, so we spec
them exclusively.

drawback. You learn when to shift, but since the mechanism shifts for you, you don’t learn how.
Friction shifting makes more clear the relationship between lever movement and derailleur
movement, teaching you shifting concepts and fundamentals that will make you shift better with any
type of shifter. This isn’t of concern to experienced riders who were raised on friction shifting, but
it should matter to beginners who wish to develop a valuable skill. Friction shifting isn’t foolproof,
but it doesn’t graduate fools, either.
FRICTION SHIFTING IS AS EASY AS
Just move the lever until the chain engages on the cog you want. Ifyou slightly overshift or undershift,
you'll hear the chain rub, but pushing or pulling the lever a wee bit (“trimming”) centers the derailleur
directly beneath the correct cog and stops the rubbing. Sometimes on hills you have to “sneak in” a
shift: Accelerate briefly, and when your left pedal is nearing the bottom of the stroke, shift. Then
“float” the pedals until the shift takes, usually within a half-a-pedal revolution. You might not
succeed on your first attempt, but it’s not the headache the Indexing Brigade claims it is, either. With
just a little conscious effort, your skills will improve rapidly.

A MINOR PROBLEM, EASILY SOLVED. LEM. THIS IS “TRIMMING.” IT’S EASY.
FRICTION ROLLS WITH THE PUNCHES
Friction shifting works with every brand of derailleur, cable, housing, and gear cog ever made, from
any country, in any combination. It’s not nearly as sensitive as indexing to kinky cables, blown-out
cable housing, creative cable routing, misaligned frames, wear and tear, and time. That’s why you
see old, cheap, beat-up, ugly bikes still shifting fine in friction. Friction shifting is tough and tolerant;
it doesn’t cry “foul!” when things aren’t perfect.
FRICTION SHIFTING IS MORE HUMAN, LESS MECHANISTIC
Indexing makes you dependent upon the mechanism instead of yourself. When indexing fails for any
reason, a friction option and your own shifting skills will bail you out.
FRICTION PUTS YOU IN CONTROL
You get the blame when you blow it and the satisfaction when you don’t. And just as there are
photographers who don’t use point-and-shoot cameras, flyfishers who fish nymphs without bobbers,
and cooks who shun microwaves, there are cyclists who enjoy the intimacy with their bike and the
improvement of personal skills that friction encourages.

Cs” JOINING THE FRAY, some experts claim you need only front suspension, because front impacts are
the ones you feel the most. Still other experts recommend front and rear suspension.
Many proponents of suspension have motorcycle backgrounds, and believe bicycle engineering
and design is archaic—or at the very least, in dire need of updating.
Bicycle loyalists point out that since motorcycles weigh 450 pounds, good technique and cushy
tires can’t help much, so they need extra suspension; but bikes don’t, since they are lighter.
Undeniably there are trails, terrain, events, and riding styles that require something other than
a standard bicycle to get the best results. But these situations are the exception, not the rule. For most
riding, the important things to look for in a mountain bike aren’t its capacity to neutralize bad
technique in a boulderfield or shave seconds offa downhill time trial, but its ability to carry you safely
and enjoyably over the trails you ride every day.
TECHNOLOGY IS IMPOSED ON THE LAND, BUT TECHNIQUE MEANS CONFORMING TO THE LANDSCAPE.
ONE FORCES A PASSAGE, WHILE THE OTHER DISCOVERS IT. THE GOAL OF DEVELOPING
TECHNIQUE IS TO CONFORM TO THE MOST IMPROBABLE LANDSCAPE BY MEANS OF THE GREATEST DEGREE

- In recent years most manufacturers have
resorted to supplying their bikes with “positive
front-wheel retention devices” (PFwWRD) which
negate all benefits of the quick-release. This
measure is not meant to compensate for any
deficiency in the q/r itself (only an act-o’-God

The Art and Science of Recycling Inner Tubes
‘THORNPROOF TUBES, tubeless tires, tire liners,
and self-healing tubes are fine, but you'll never
be completely comfortable on a bike until you
can fix your own flats. Fixing flats is easy, and
prevents waste.
You'll need: a leaky inner tube, tire levers, a
patch, some glue, anda piece of sandpaper. (Get
a repair kit.)
c= Pry the tire off
the rim, then remove
and inflate the tube
and find the leak. Two
small holes suggest a
pinch-flat, caused by
riding underinflated
tires over bumps.
4 Abrade an area
slightly larger than the
patch. It’s easier to
abrade if you roll the
flat tube around your
pump. Discard the
crumbs.
Es Spread ona thin,
even layer of glue. Be
quick, not compul-
sive. Inflate the tube;
escaping air will mark
the hole. Then deflate
it and let the glue dry
completely.
“E41 Holding the
clear backing, press
the patch over the
puncture. To seal it
tightly, rub a hard,
smooth edge back and
forth over the clear
ES”. Leave the clear
backing on or peel it
off from the inside
out. Inflate to check
for leaks. If it holds,
put talc or dirt on the
patched area to pre-
vent excess glue from sticking to the tire. Put-
ting talc all over the tube prevents time and heat
from sticking the tube to the tire, too.
C= Before putting
the tube back in, check
the inside of the tire
for anything that may
have caused the punc-
ture. Put the inner
and inflate it just enough to remove wrinkles.
Starting from the valve, work both beads onto
the rim simultaneously, pulling and stretching
the tire as you go. Sometimes the last part is hard
to remount. If so, use tire levers. The Var style
(illustrated) works particularly well.

WAXING IS WONDERFUL. Everything the chain touches stays clean. You will need:
DOUBLE BOILER
Just a small

inside a
larger pot.
PROCEDURE
mi Degrease the chain with biodegradable solvent; dry
thoroughly.
= Fill the big pot with 3° of water, put the wax into the
small pot, and put the small pot into the big pot. CAUTION:
WAX IS FLAMMABLE; ALWAYS USE A DOUBLE BOILER.

the chain with a spoke or piece of coat hanger bentin an “S’.
Hang it up to dry.
BREAK OFF THE CLINGING CHUNKLETS, work the
chain a bit to make it flexible, and put it back on.
It may skip in the first one to two minutes of easy
pedaling, but it'll be ready to ride again after
three or four minutes, and in dry conditions will
last 400 to 700 miles. Best of all, everything the
chain touches, from calves to derailleur pulleys,
stays clean. After several rewaxing cycles the
wax gets dirty and needs replacing.

— DEEs-S —
The MB-S is slightly lighter than the MB-6, largely due
to its aluminum chainrings—a rare treat on bikes of this
price. The top-mount shifters are another unusual spec.
If you look around, you'll notice that most mountain
bikes selling for less than s600 have underbar shifters,
either Shimano’s Rapidfire™ or SunTour’s X-Press™,
while the same manufacturers’ more expensive models
have top-mounts. This might lead you to believe that
underbar shifters are somehow better for low-priced
bikes, while top-mount shifters are better for more
expensive bikes. Actually, we strongly believe that top-
mounts are better, period, and on page 7 of this catalogue
we tell you why. This year the top-mount shifters on
our MB-5 are Shimano MT-625’s, bike spec’er talk for
Shimano Deore px. These are the same shifters as on this
year's MB-3, and they are far more costly than the price
of the MB-5 would ordinarily warrant.

OUR MOST POPULAR MODEL
Last year the mB-6 was our biggest seller, maybe because it was the only bike in its price range with
top-mount shifters. At this writing we can’t say if that will again be the case, but the mB-6 has more
to offer than just good shifters. It has the same geometry and ride as our most expensive models, and
just a fraction of the cost-saving tricks found on other mountain bikes in this price range. The only
thing remotely unhip about it is its lack of toe clips and straps. If you ride off-road, and enjoy keeping
your feet on the pedals on bumpy descents, spend another sio or so and put them on yourself.

According to the company profile, the readers
are “fast recreational riders,” and new cyclists
and weekend warriors will learn a lot from
Bicycling. There's some friction between us,
however, dating back to the July ’90 issue, when
it unflatteringly called us “retro-grouches” and
accused us of stifling techno-progress by not
specing many of the new components whose
main benefit seemed to be that they were new.
We disagree with Bicyc/ing’s view that cycling’s
major attraction to new riders is new technol-
ogy. Overall Bicycling is well-written,
occasionally stimulating, and it deserves praise
for its role as a leader in cycling advocacy.

In June ’84 six editors and two ‘ad salespeople

Bicycle Guide is written for people who already
know a fair amount about bikes and don’t re-
quire a lot of hype to maintain their interest.

Mountain Bike Action is the most outspoken of

parent, High Torque Publications, also pub-
lishes Motocross Action and Crash and Burn, and
the influence is unmistakable. 724 doesn’t tol-
erate road-bike traditionalism, and it fawns over
gadgetry too much for our tastes, especially if
the gadget has motocross roots. On the plus
side, MBA is frequently the only publication to
take on a controversial issue, and its disregard
for advertisers’ feelings is refreshing, if some-
times misguided.

Last year MCB said of our bikes, “You either love

bewildered—and required some explaining to
our parent company in Tokyo. In any case, we
think the tag is more self-descriptive. For our
taste, MCB’S editorial is too chatty, it overuses
quote marks and exclamation marks, it’s too
quick with praise, and it rivals Bd in its use of
flash-frozen, neon-clad Southern Californians
wearing brand new cycling togs and expensive
plastic sunglasses. However, it has improved a

Choosing Appropriate Technology
YEARS AGO PRO RACERS AND NONRACERS rode equipment that was similar in concept, if not cost, and
the equipment knowledge gained in races carried over to recreational equipment. But in the
specialized world of modern racing, equipment plays a bigger role than ever before, and many
modern frames and components are being designed specifically for a competitor's special needs.
These innovations are not always right for recreational riders, no matter how fit or fast. In the real
world of weekend rides and commuting to work and school, a component designed to shave seconds
in time trials, though glamorized in pro racing, may not be your best choice.
RETHINKING PERFORMANCE
There is so much emphasis these days on racing, winning, and achieving one’s personal best. In fact,
a lot of people define performance only in terms of speed and physiology. But real performance
includes fundamental all-around skills like shifting, braking, cornering, and threading your way
across town and through traffic safely, legally, and without scaring anybody. Performance is more
than aerobics, aerodynamics, biomechanics, and computer readouts.

Wonderful Wool for] Beautiful People
IS YOUR CYCLING JERSEY PETRO OR RETRO?
YOU CAN WEAR a wool jersey for five straight

WOOL CYCLING JERSEYS LAST A LONG TIME
Just as the best'and most durable rugs are wool,
so, too, are the best jerseys. With regular use and
normal care, a fine wool jersey should last you at
least five years. (Mothballs are toxic, by the way;
if moths are a problem,
use cedar.)

that they fight over oil.

It's 1992—Do You Know t What Your Q-Factor Is?

Q-FACTOR IS THE DISTANCE BETWEEN THI OUTSIDE OF THE CRANKS

Five years ago a typical
touring or mountain bike
Q-Factor was 154mm.
Finally, the chain-
stays on many modern
bike frames are wide at
Most modern triples are

about 162mm, and some crank arms pass. (See A,

high as 182mm.
WHAT HAPPENED?
First, unfavorable currency ex-
change rates have made it necessary
to reduce crank manufacturing costs
in order to meet certain “price
points.” To maintain strength with
less costly materials and methods,
thicker crank arms and larger radii
between the crank arm and the spi-
der have become necessary; these
increase Q. (See Figure 2.)
Second, some modern front de-
railleurs are so wide they require a
chainring-to-crank arm gap of
13.5mm. (On older cranks this gap
was as small as 7mm.) A bigger gap,
increases Q. (See Figure 3.)
Third, increasingly wide rear
overlocknut dimensions require that
the front sprockets be set out farther
from the seat tube—to keep the
chain angle reasonable—and this
leads to higher Q-factors. The first
mountain bikes had 126mm over-
locknut dimensions; this climbed to
130mm (we stayed there), and now
most are at 135mm or 140mm.
Spacing the rear cogs farther
outside encourages manufacturers
to move the chainrings farther out-
side, too—to keep a good chainline.
This is done with a longer crank
spindle, and increases Q-factor.

Crank makers like their
cranks to clear all frames,
so they design up to
ro.5mm of offset in the crank
arms—measured vertically from
the dustcap to the outside pedal
hole. This increases the Q-Factor.
CAVEAT FOR SHORT RIDERS!
For any given Q-factor, a rider with
shorter legs is more spread-legged
than a rider with longer legs. Logic
suggests that pedaling with your
feet farther apart isn’t as aerody-
namic or as powerful as pedaling
with your feet closer together, and
our experience suggests that you
can hurt your knees by riding with
your feet too far apart.
Years ago custom bicycle
builders in Japan recognized the
merits of a low Q-Factor, and se-
lected the narrowest cranks—usu-
ally the French T.a. brand—for
their short-legged customers. At
the turn of the century in England
and America, the pedal-to-pedal
distance was known as “tread,” and
a narrow tread” was highly prized.
“Q-Factor” isn’t a new concept,
just a highly ignored one. The
media is doing a fine job of keeping
the “Q-Factor” issue alive, and
crank design should improve in the
next few years.

We believe that in the past two years the RB-I frame has been
ridden to more U.S. amateur victories than any other
production frame. We know full well that riders,
not bikes or frames, win races; but the RB-I frame
is all the frame any rider needs.
The RB-I is the best-handling production

portions are extreme, a custom builder will be
hard-put to improve on it. The geometry has
been refined over many years, and now it’s as

Until we tried them six years ago, we thought bar-end shifters

The tubing for the RB-1—Ishiwata o19£, 0228, and 0248, depending on frame size and application
(on some sizes we mixed tube sets)—is Ishiwata’s best-quality seamless tubing, and the equal of any
chrome-moly in the world. It was developed in 1982, and its conventional shape and diameters have
remained unchanged through years of marketing hype, triathlon influence, and the oversize craze.
It’s the same tubing we used on last year’s RB-I, but with a new decal. (Bicycle trivia fans note: Freddy
Maertens won the 1976 World Championship on a frame made from Ishiwata tubing. The tubing
we use on the RB-I is an improvement over that.)

One
Far-Forward Frames Fad or Faster?
BY LENNARD ZINN
A FEW YEARS AGO triathletes discovered they
could ride faster if they moved their saddles
much farther forward. They won races in this
position, others copied, and soon bicycle frame
builders started building forward-position
frames designed specifically for this far-forward
position. What appeared to some to be just
another triathlon fad was “legitimized” a couple
of years ago when American pro road racer and
’84 Olympic gold medalist Alexi Grewal started
winning road races in this forward position.
Alexi had problems with lower back and hip
pain to the point that he considered retirement,
though, and the far-forward position relieved
his pain.
The motive for moving the saddle forward
is sound. Aerodynamic drag increases geo-
metrically with speed, and at race speeds of 30
mph or so, aerodynamic drag is by far the largest
speed-robbing force. To be aerodynamic, and
therefore competitive, you must keep your up-
per body low and flat. If you happen to have a
stiff pelvis, or tight hips or hamstrings, your
lower back will arch when you try to get low and
aerodynamic on a standard bike. A far-forward
position opens up the angle between the thighs
and the torso, thereby flattening your back even
if you're stiff.
Often triathletes are less able to tip their
pelvises forward because they are new to cycling,
and it takes time to become flexible. The top
European pros in the Tour de France, though,
stay low and flat, even though their saddles are
far back. Ittookthema long time to develop that
position, and they have fundamental technical
reasons for staying back, well behind the cranks.
Going far-forward on a standard bike (by
reversing your seat post, moving the saddle
forward and using any of the triathlon-style
bars) changes your weight distribution. Weight
distribution is key to good handling, though,
and throwing it off makes the bike harder to
ligt webaRele Di GElnsminOuNee:
control around high-speed turns, in traffic, or in
a pack of riders.
Riding far-forward on a frame designed for
this position is better. Bicycles tend to handle
best with about’55 percent of your weight on the
rear wheel; and you can achieve this on a frame
designed with an extra long top tube, extra short
chainstays, and a few other extras—but there’s a
cost. With more weight on your arms, steering
is sluggish, becoming even moreso when pedal-
ing, since your arms are brac-
ing you from pushing forward

racing tire. A small tire is a fast tire, but that’s its
only merit. Small tires are not suitable for
rough-road riding, longer rides, or carrying
loads. Unless your bike is strictly a race bike, at
some point you're sure to want the versatility
you get with a larger tire.
Far-forward pedaling emphasizes a strong
downstroke powered entirely by the quadriceps.
While triathletes may favor this sort of style due
to its similarity to running, it has its weak points

nontriathletes alike. To do the

When using the smallest MOST RIDERS. other points in the stroke. Lac-
or largest rear cogs, the short
chainstays of a far-forward frame cause the
chain to leave the front chainrings at avery sharp
angle. This makes for noisy, imprecise shifting
and will accelerate wear on chains, cogs, and
derailleurs.
Also, current front derailleurs are designed
for 72- to 75-degree seat tube angles, and the 78-
degree—and steeper—seat tube angles on these
bikes move them as much as an inch ahead of
ideal, resulting in slower shifting. What's more,
the bottom of the trailing edge of the cage is
rotated forward on the crank circle, and when
the chain is on the inner chainring and any of the
two or three smallest rear cogs, it will drag on the
bottom of the front derailleur cage—reducing
the number of available gears.
The extra short chainstays create their
own problems. Since the rear tire is so close to
the bottom bracket, it interferes with the front
derailleur cable. To avoid this, the cable
must be routed in a circuitous (and higher
friction) course.
Poor chainstay clearance caused by the
short chainstays limits you to a small-volume
tic acid buildup in muscles is
greater at peak forces, so unless you're accus-
tomed to far-forward pedaling, you may get
tired faster. (A triathlete with an up and down
pedal stroke may be equally inefficient farther
back—and perhaps less aerodynamic—so the
forward position may be his or her best choice.)
The classic, supple pedaling style distrib-
utes power more evenly over the entire pedal
circle, which is why it’s best for most riders.
If you compete, particularly in triathlons,
and for physiological reasons are unable to pedal
as aerodynamically in a smoother, more power-
ful position farther back, then a far-forward
position may be just the ticket. And it might be
right for you if a majority of your rides are solo
time trials on flat-to-rolling terrain. But for
most riding, from racing to commuting to ath-
letic weekend group rides on a variety of courses
and terrain, youll do best with a traditional
frame and classic pedaling form.

The Benefits of alittle Frame Flex
AND OBSERVATIONS ON OVERSIZED TUBING
A BIKE FRAME IS A SPRING, so it’s supposed to flex.
Just as a spring can be too springy, a bike frame
can flex too much, which is why the Myth of
Stiffness originated. Since too much frame flex
is obviously bad (the bike shifts by itself when
you climb steep hills and feels soft, whippy, and
hard to control on severe descents), it’s easy to
sell people on the notion that all flex is bad.
But a /ittle flex does a lot of
good. It increases frame life by dis-
tributing stress that would other-
wise concentrate at the joints; it
adds comfort; and it makes a bike
feel alive, like a muscle.
The Stiffness Sellers say the
energy that goes into flexing the
frame is energy diverted from the
job of propelling you forward—
an idea that seems to make sense,
and one that certainly convinces a
lot of people. After all, it’s hard to jump high
from a bed of soft, cushy foam.
But you can jump higher from a sprung
wooden floor than from a rigid cement floor,
because the little amount of spring aids your
effort. A bike frame flexes under the pressure
of pedaling, and, as it recovers from the flex,
releases some of that energy to help you go.
Obsession with stiffness is an American
phenomenon. In Europe the toughest races,
fastest sprints, and most demanding cyclo-cross
battles are won on frames that, by the rigid
standards prevalent here, would be considered
downright whippy. The most efficient frame for
you is one that flexes the right amount for your
weight, pedaling style, and the terrain you ride.
Part of what makes our bikes ride as well as
they do is the controlled amount of flex we
design into the frames.
INNER: 31.8MM—ORIGINAL
OVERSIZED DOWN TUBE.
OUTER: 34.9MM—
TOO FAT FOR US.
OVERSIZED FRAME TUBING: THEN AND NOW ,
Oversized frame tubing makes a frame stiffer
and stronger, but at some point the drawbacks
outweigh the benefits.
When the first mountain bikes were made
in 1979, the designers recognized that frames for
off-road riding ought to be more robust than
frames for road riding, so they increased the top
tube from 1" to 24" and the down
tube from 1%" to 14". This original
oversizing, about 12 percent, trans-
lates to an even higher increase in
strength and rigidity. It remained
unchanged for several years be-
cause it worked well.
_ Really fat tubing makes sense
in aluminum; in fact, it’s an engi-
neering requirement. Since alumi-
num generally isn’t as strong as
steel and has just one-third of
steel’s inherent rigidity, it needs to be larger in
diameter to compensate. What's more, alumi-
num frame tubes require relatively large-radius
welds for strength. That’s why all welded alumi-
num bike frames are so fat.
But in steel, once the strength and rigidity
requirements are met, as we believe they are
with the original oversizing, further increases in
diameter add unnecessary weight.
For mountain bikes, we prefer the original
oversized tubes, but it’s not wise to choose any
bike solely on the size of its frame tubes. Look

package that makes the most sense to you.
Meanwhile, terrain, riding styles, and body

and for most riders the original 12 percent over-
sized mountain bike tubes continue to make as
much sense and perform as well as ever.

HISTORY AND DESIGN
MANY SCHOOL DISTRICTS in Japan forbid stu-
dents to commute with drop bars, because they
think drops encourage fast, crazy riding. So to
appeal to the kids who like drops, “semi-drop”
bars were developed. We rode “semi-drops” a
few hundred miles and found them to be a
blessed alternative to
the single-hand place-
ment constraints of
regular flat bars. But
we improved them.
Using “semi-
drops” as our base, we
designed Moustache
Handlebars with a
larger forward radius
to better fit our adult-
sized palms. We rode 2,800 km on road and dirt
with four prototypes before settling on the final
moustache shape. It’s just what we wanted.
Lert: TYPE 1 FITS ROAD LEVERS AND BAR-CONS.
RIGHT: Type 2 FITS MTN LEVERS, SHIFTERS, GRIPS.
HOW GOOD ARE MOUSTACHE HANDLEBARS?
Nor PERFECT. Any drop-bar fan will miss the
next-to-the-stem hand position. The advan-
tage over drops is quicker access to the ends of
the brake levers, making Moustache Han-
dlebars equally good for quick braking and pow-
erful braking, just like mountain bike brake
levers. The advantage
over flat bars is having
more hand positions.
You can ride Mous-
tache Handlebars for
hours without grop-
ing, and you'll appreci-
ate them even on a
quick trip to the store.
And the Moustache
Handlebars look good,
too. The retro-attractive curves go well with any
bicycle. Moreso, we think, than the angular,
afterthought look of bolt-ons.

IS A TERRIFIC BIKE
The x0-1 is the most versatile, most exciting bike we’ve ever made; and under the legs
of a strong, skilled rider, it can do almost anything. It excels on long, fast road rides;
it’s the best commute bike we've ever ridden; add a third chainring, if necessary, and the
XO-I becomes a dandy touring bike. What’s more, with drop bars and Specialized 26" x 1"
Turbo™ tires, we can’t imagine a better road bike for short people than a 42cm XO-I.
The XO-1 has road geometry, because we wanted it to handle like a road bike; road
tubing, to keep the weight down; and standard reach sidepull brakes, because they work
well and look good.
Please look at the fork crown. Our
Japanese staff originally designed it fora
touring model called At/antis. It’s the
only quality fork crown we've seen
with internal clearance sufficient for
tires up to 1.6"; and it has an elegant,
intricate design that helps make it
the Most Expensive Fork Crown In
the World. We hope you appreciate
it, because it increased the price about
$30 over a unicrown fork, and about
$25 over that of a pressed-and-welded
crown. The most glaring feature of the
xo-1 is the Moustache Handlebar. Read
about it on page 35. Regardless
of what other bikes you already
own, the xo-ris the bike you'll ride
most of the time. Limited production
of 1,000.

Dae COMPARED WITH A TYPICAL “HYBRID,” THE X0-3 HAS
More traction, thanks to tires with road tread.
A lower standover height, for more crotch clearance.
A shorter top tube, for a more upright position.
Less weight.
The best-designed, best-fitting
z00c-wheeled bike of its type, and
strong competition for anyone’s $400
“hybrid.” The x0-3 has a lower
standover height than most hybrids
with 7ooc wheels, so it fits short-
legged people better. It has a shorter
top tube, for a more upright riding
position. The XO-3’s road-tread tires
grip better than any knobbies. The
ARC handlebars are the XO-3’s single
neatest feature. We've retrofitted
several of our personal bikes with
them. They're really nice.

BELOW WE DESCRIBE FOUR COMMON
PROCESSES USED FOR MANUFACTURING
ALUMINUM ALLOY BICYCLE PARTS. THERE ARE TRADE SECRETS INVOLVING
MINUTE DIFFERENCES IN HEAT, TIME,
AND ALLOY, BUT THE BASIC PROCESSES
ARE THE SAME REGARDLESS OF WHO’S DOING THE WORK.
Cold Forging
Dia-Compe #986
CANTILEVERS BEGIN AS
BAR STOCK 6061-T6
ALUMINUM. FirsT,
THEY RE CUT, BENT, AND
PREPPED FOR FORGING...
IN COLD-FORGING, the alloy is warmed to a
temperature just below the point at which the
crystalline structure is changed, then bashed
into shape by means of forging dies (like molds).
Brakes can be formed in one or two bashings of
up to 330 tons each, but more complex and
massive parts—crank arms—require up to six
whomps of up to 660 tons to reach final form.
... THEN SMASHED TWICE. IN THIS CASE,
THE SECOND AND FINAL SMASHING
COMPLETES THE SHAPE.
Top: AFTER THE FIRST
STOMPING.
MippL_e:. AFTER THE SECOND
STOMPING, SHOWING EXCESS.
BoTTom: EXCESS REMOVED,
READY FOR FINISHING.
Cold-forging alloys are high-strength to begin
with (cold-forged cranks are often made from
7075-16; 74,000 psi), and the forging process
adds grain structure along the curves of the
piece, much like the grain in a crooked tree
branch. Cold-forged parts are typically thinner,
lighter, stronger, more accurately made, and
more expensive than cast parts.
hot Torging
IN HOT-FORGING, a slightly lower-strength alloy (for cranks, around 65,000 psi) is heated,
softened, then stomped into shape with one fell blow. Hot-forged cranks cost less to make than
cold-forged cranks mainly because the tooling lasts longer and fewer dies are needed.

Gravity-Casting
THE ALUMINUM IS
MELTED...
In Gravity-CasTING, still another alloy (typi-
cally AcIB-T4; 42,000 psi tensile strength) is
melted, then poured into a mold and allowed to
cool naturally. During the cooling, air bubbles
gravitate upwards and out—hence the term.
The alloy isn’t as strong as that used for hot- or
cold- forging, but it is about 30 percent stronger
than the alloy used in melt-forging. Compared
with melt-forged parts, gravity-cast parts tend
THEN POURED INTO A
MOLD...
AND ALLOWED TO COOL
NATURALLY.
to be more expensive, stronger, lighter, and less
brittle (not that brittleness or strength are prob-
lems with well-made melt-forgings). Gravity-
castings, like hot- and cold-forgings, can be
anodized, and consequently the -finished pieces
can be difficult to distinguish from hot- or cold-
forgings. Some cranks, such as the excellent
Specialized sT-4, are gravity-cast and then, for
added strength, whomped once in a forging die.
Melt-Forging
THE ALUMINUM
IS MELTED AND
THEN FORCED
INTO A MOLD
UNDER HIGH
PRESSURE...
i |
AND COOLED
QUICKLY WITH
WATER.
MELT-FORGING is high-pressure casting, in which molten ac4c-T6 aluminum (tensile strength
approx. 32,714 psi) is forced into a mold under roughly 11,378.4 lbs. of pressure. This eliminates
bubbles much faster and more economically than in gravity-casting. The “forged” piece is then
cooled quickly with water. To compensate for the lower strength of ac4c-T6 (only 50 percent of
typical crank cold-forging alloys and 75 percent of crank gravity-casting alloys), the parts tend to be
chunkier. Since ac4c-T6 cannot be anodized, melt-forged parts never display the fine finishes
possible with hot-forgings, cold-forgings, or gravity-castings. Still, melt-forging has made relatively
lightweight, attractive, reliable components affordable to people who would otherwise ride steel.

ATube-Joining Primer
TIG-WELDING
TIG-WELDING BECAME ACCEPTED
through mountain bikes, because the
road-tubing lugs available in the early
’80’s wouldn’t work for mountain bike
frame geometries and larger tube diam-
eters. TIG-welding is a lugless process, |
and has proven itself worthy. INSIDE: NOT MUCH BEEF, TINY OVERLAPPING PANCAKES
a ce : BUT IT’S STRONG. LOOK CLEAN AND TIDY.
T1G-welding’s strong points are its
light weight (no lugs or brass), strength, and ease of fabrication. There’s little room to cheat with
a T1G-welded joint; the miter has to be perfect and the quality of the joint is clearly visible.
T1G-welded BRIDGESTONE models include: MB-3, 4, 5, 6; XO-2, 3; BB-I, and CB-I.
LUGGED JOINTS
IN A TRADITIONAL lugged joint, the lug
serves as external butting, increasing the
strength at the joint. The integrity of the
joint depends on the accuracy of the tube
miter, which is hidden by the lugs; the
dimensions of the lug; the fit between
THE LUG SERVES AS EXTERNAI CAPILLARY ACTION DRAWs the tube and the lug; and of course the
ee Seas ae a a or ar ea tHE skill of the builder. It’s often mentioned,
particularly with regard to mountain
bike frames, that lugs are confining; that a builder has to build to fit the available lugs. That’s not an
issue with us; if lugs we want aren’t available, we have them made.
Lugged Bridgestones include: MB-I, MB-2; XO-I; RB-I, RB-2, and RB-T.
PILLET-BRAZING
IN FILLET-BRAZING (pron. “fil-let,” not
jil-lay’) the joint is created by flowing
molten brass around the tubing junc-
tures. Usually the hardened brass is
slightly irregular, and most builders
then file or sand it to create a smooth,

shifters are easier to use than underbar shifters, and the
round chainrings promote smooth pedaling. Shimano
