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. . THE BRIDGESTONE BUINCWs COLRE® (CvAVTV ALL O.G UE 1992 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. EENy, MEENY, MINY, MO/CATCH A TIGER BY THE TOE/IF HE HOLLERS LET HIM GO/ EENY, MEENY, MINY, MO.

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. WK PAY A LITTLE MORE The best dealers take the time to assemble and adjust your bike properly, and charge you for it. A higher price is usually a good sign. The term “false economy” was invented for poorly assembled, heavily discounted bikes. BUY SIMPLICITY AND PROVEN TECHNOLOGY Simple things have fewer parts, fewer potential problems, are easier to repair, and give you more quality per dollar.

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. leet beReleDsGakssmisOuNee wa Belic YaCulsrenCcrAiwAnL O;GaURE 1.959°2 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. TeHOE) B_RoIeDiGeEsSsOUNTE BrlaGava ColpEws GrAciwAGLEORGRURE LOO? 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. "a 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.

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. “DOUBLE, DOUBLE TOIL AND TROUBLE...” —SHAKESPEARE, MACBETH IN ANYTHING AT ALL, PERFECTION IS FINALLY ATTAINED NOT WHEN THERE’S NO LONGER ANYTHING TO ADD, BUT WHEN THERE’S NO LONGER ANYTHING TO TAKE AWAY, WHEN A BODY HAS BEEN STRIPPED DOWN TO ITS NAKEDNESS. —ANTOINE DE SAINT EXUPERY SEVIS MIVA ID GIS HIrOwmwmis WUE vwEIiIs SCAWAILOE Ws WOO THERE ARE VERY FEW ACCOMPLISHMENTS OF ANY VALUE THAT CAN BE GAINED WITHOUT PRACTICE, AND THAT WHICH TAKES THE LEAST TIME TO LEARN IS USUALLY THE LEAST VALUABLE WHEN LEARNED. -TuHeE EaGLe Bicycle Co.

AND IT MAKES EVEN THE MOST STUBBORN FRICTION-SHIFTING FAN RE-EVALU- ATE THE REASONS FOR... Friction Shifting In An Indexing World Indexed shifters have click-stops which tell you exactly how much to move the shift lever to shift; and if everything is properly adjusted, you can’t miss a shift. That’s the appeal, but it’s also the 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.

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 OF SKILL AND BOLDNESS SUPPORTED BY THE LEAST EQUIPMENT. —Doue Rosinson, Great Paciric IRON WorKS CATALOG, 1974 ie HE Ee ba Rele Di Gee SiO NNGE = Bel. .C.Yac Li Es CeAwI Al, O'G.UE 19:92 The Quick Release and How to Use It In AMERICA before the Bike Boom of ’71 only racers and outcasts rode bikes, and only racing rather, its purpose is to prevent the wheel from dropping out of the fork if the q/r is not closed bikes had quick-release (q/r) wheels. properly.

This is troubling. - 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 can open a properly closed q/r during a ride); THE Q/R LEVER OPERATES A CAM.

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.

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. Good Business or Good Design?

FIGURE 1 Q-FACTOR IS THE DISTANCE BETWEEN THI OUTSIDE OF THE CRANKS AT THE PEDAL HOLE. IT DETERMINES HOW FAR APART YOUR PEDALS ARE, WHICH IN TURN DETERMINES HOW FAR APART YOUR FEET ARE WHEN YOU PEDAL, WHICH OF COURSE AFFECTS \ERODYNAMICS, BIOMECHANICS, AND PEDALING FEEL. TeHee BERSISD GEE Se OPN DE WIG we ib ( FIGURE 2 AS TAS TAO GSU IES 9919/2 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 the point by which the Lerr: COLD-FORGED CRANK TYPICALLY HAS SMALLER RADIUS, LOWER Q. RIGHT: MELT-FORGED CRANK HAS LARGE about 162mm, and some crank arms pass. (See A, prestigious ones go as Figure 1, facing page) 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. RADIUS, INCREASING Q. FIGURE 3 MODERN “WIDEBODY” FRONT DERAILLEUR DOESN’T FIT WELL BETWEEN THE CRANK ARM AND CHAINRING OF A LOW-Q_CRANK. SOLUTION: NARROWER FRONT DERAILLEURS! FIGURE 4 Lert: MELT-FORGED CRANKS ARE THICK, INCREASING Q. RIGHT: COLD-FORGED CRANKS ARE SKINNY, KEEPING Q_ Low. 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. nN vw RAD DRUID GBSROMND BUICK CHD CATRALOGWIS LODZ THE PROVEN, LONG-LASTING ALTERNATIVE TO CARBON-FIBER —- RS-i — bee TECHNICAL DATA bes /PGRADES FROM RB-2 sizes: 50, 53, 54.5, 56, 57.5, 59, 62cM Lighter frame and seamless tubing FRAME WEIGHT: 4.2 LBs.

Until we tried them six years ago, we thought bar-end shifters were only for elderly tourists. We've been riding them for five years now, and finally have the nerve to spec them on a bike. They take a ride to get used to; and as many an elderly tourist will tell you, they're wonderful. WHY NO CLIPLESS PEDALS? Any of the popular clipless pedals would have added s80 to $160 to the price of this bike, and for that price we thought it best = to let you do your own picking. The stock MKS Sylvan pedals have a proven Noecent weigh just 260 gr. per pair, and will last the average rider 12,000 miles, no problem. The excellent chromed steel Christophe toe clips are a classsic touch from a bygone era. WHAT YOU NEED TO KNOW ABOUT ISHIWATA TUBING 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.) nN ™N THE BRIDGESTONE BICYCLE GAT ALIOIG UE 199972 LOW BUDGET, HIGH SPEED The RB-2 has the same geometry and road qualities as the RB-1, with onlya slightly heavier frame and less expensive parts.

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 off the nose of the saddle on the downstroke (which is now BICYCLE CATALOGUE THE CLASSIC, SUPPLE PEDALING STYLE DISTRIBUTES 1992 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 for both road racers and nontriathletes alike.

WHICH IS WHY 11'S BEST FOR sating for the reduced force at 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 BRIDGESTONE BelnCoya Gels CARINILEO® EWI 1OO?7 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 at the entire bike as a package, and buy the package that makes the most sense to you. Meanwhile, terrain, riding styles, and body proportions haven’t changed much since 1979, 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.

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.

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.

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. x y Nore: IN THE DESCRIPTIONS, “WHOMP,” “STOMP,” “BASH, »“ SMASH,” AND “FORGE” ARE USED INTERCHANGEABLY. matt ict + Ailes ic iets als ate te Dek BeReeDEGariseleOsNsE s Bl CuveCelLiE we CLA A L1O)G.U EE 1:9.92 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. 43 THE BRIDGESTONE BICYCLE CL/NAVINIE OO) WIS alo © 7 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, appealing joint that when painted gives MOLTEN BRASS FLOWS THE LARGE RADIUS DISTRIBUTES the bike an intriguing, one-piece look. A INTO AND AROUND THE STRESS AND GIVES THE JOINT A JOINT. ONE-PIECE LOOK. high-quality fillet might create the strongest of all frame joints, but there’s no way to tell the quality just by looking. Anybody can puddle” brass, but a skilled builder uses aminimum of heat and time to do it; others torch away, then cover their mistakes with putty and paint. on i SOUR TeHebee Bekele DsGekeSisO INGE BalnCaya Cask COAMTWASROIGEUTE 19.92 Lighten Questions PLEASE FILL OUT THIS QUESTIONNAIRE (OR A‘PHOTOCOPY THEREOF) AND MAIL IT BACK TO US.
