RITCHEY

For the past 20 years, I’ve built, ridden, and raced bicycles. Cycling has enhanced the quality of my life with a never–ending influx of fun, thrills, and fitness. That’s probably why I enjoy designing and creating new and better performing components for bicycles.
I hope that my exciting new line of components can make your bicycling experience a better one.

MOUNTAIN TIRES

No one designs mountain bike tires like Tom Ritchey. Every Ritchey tire is painstakingly thought out to provide maximum traction with minimum rolling resistance and minimum weight. Before a final design is reached, many field tests are made by Tom and his team riders to ensure performance they will want to ride on. Every tire is also manufactured with the highest quality and standards in the industry. This year brings two exciting additions to the mountain bike tire line. First, we’re pleased to announce the introduction of the new MegaBite Z–Max. The Z–Max combines all of the latest refinements of Ritchey’s Vector Force Analysis (VFA) with three full years of race–winning MegaBite experience. Once again, Ritchey sets a new standard in tread design technology with the super traction MegaBite Z–Max in both the 2.1″ and 2.35” widths. The second addition to the line is our new special limited edition “WCS” (World Champion Series) low density rubber line of superlight tires. This series is available in each tire design in either standard black or special red, a softer, more puncture resistant compound. Ritchey tires have always been the lightest full–width tires, and with the new “WCS” series, the lightest just got lighter!

ROAD TIRES

Tom Ritchey has combined years of nationally ranked road racing experience with his innovative and race–winning Vector Force Analysis (VFA) technology to create the world’s first road racing tire using VFA. Never before has a road tire so accurately addressed the forces imposed upon it. The result is road gripping traction and a super low rolling resistance that combine to make it the ultimate in road tire performance. The Road Force is standard equipment on the Ritchey Road Race Team bikes, piloted by National and World team riders including Ruthie Matthes and Bobby Julich. Ritchey road tires are available in clincher and tubular models, in a full complement of diameters and widths.

ROAD FORCE
Ritchey hits the road with the world’s first Vector Force Analysis road tires, using unique parabolic grooves for superior cornering and a special contour for an ultra low rolling resistance.
CLINCHER
◆ 700x20c | 220 grams | 66 tpi
◆ 700x20c Kevlar | 180 grams | 127 tpi
◆ 700x24c | 230 grams | 66 tpi
◆ 700x24c Kevlar | 200 grams | 127 tpi
◆ 700x28c | 270 grams | 66 tpi

VANTAGE RIMS

Ritchey Vantage rims have become the standard for race–winning performance in rim technology. The trademark “V” cross section provides optimal lateral rigidity and at the same time reinforces the critical spoke area. This design eliminates the need for heavy eyelets, so while the strength of the rim is maximized, the weight of the rim is minimized. The Vantage advantage is a rim that accelerates faster, climbs quicker, and as a result maneuvers on single–tracks with superb agility. That’s why Vantage rims were the number one choice of top pros in the 1990 and 1991 race seasons. Ritchey’s latest is the exciting light weight Vantage Pro “WCS” MTB rim (395 grams). Also offering a new level of minimal weight, along with improved performance and durability, is the new Vantage Comp Road for the discriminating road rider.

PROELITE WHEELS & PROCONTROL

RITCHEY PROELITE WHEELS
A race proven, limited edition “pro–quality” set of team wheels!

Second only to the frame, wheels are known for their importance to the performance of bicycles. Their weight and strength are critical factors which directly influence the way a bike will ride and feel. A wheel is essentially a dynamic structure that is asked to take the first onslaught of punishing abuse. Well designed, shock absorbing wheels are mandatory for mountain bike riders. Taking weight off the wheel, in however small increments, is a challenge of the highest order. The risks are self–evident, but the liveliness of a strong, light, agile, trail gripping pair of wheels are unparalleled to any other bicycle component.
That’s the trick to the Ritchey ProElite Wheels. Only a very limited number are made annually, due to the labor intensive effort put into each and every set. ProElite Wheels are meticulously hand laced, trued, tensioned, and individually serial numbered by Wheelsmith.
ProElite Wheels start off with Ritchey’s new ultra–light 395 gram Vantage Pro Rims. Then Ritchey makes use of the weight–saving Shimano Ultegra front hub and the Deore XT 7–speed rear hub. These are laced by Wheelsmith technicians using their finest quality butted 15/17 (front) and 14/16 (rear) spokes. Finally, ProElite wheels receive Ritchey’s new ultra–light MegaBite Series “WCS” Kevlar beaded tires and Pro “WCS” Latex tubes. And if that’s not enough, Wheelsmith even guarantees the wheels against spoke breakage and for trueness.
ProElite Wheels are as fast as wheels get. By shedding over one full pound off the wheels of your bike, you can actually feel the difference. Previously these race wheels were only available for the Ritchey P–22 Team race bikes and other professional race teams, so now is your chance to get a set of these limited edition wheels.

RITCHEY PROCONTROL An advanced system of control components for race–winning performance!

ProControl is Ritchey’s high performance front end control system for mountain bikes. ProControl features eight different race proven components, as used by the Ritchey Race Team and many other pro riders.
Ritchey’s ProControl succeeds as never before in making a super light and highly agile control system. The ProControl system includes the very latest in component design and technology, including the Logic triple butted fork with the Force Directional Steerer (700 grams), the Logic Comp Headset (110 grams), the Cliff Hanger drop–cable hanger (17 grams), the Force Comp Stem (290 grams), the butted ProLite “WCS” bars (120 grams), True Grips (100 grams), Logic Brake Levers (95 grams/pair), and Logic Cantilever Brakes (145 grams).
The ProControl system continues Ritchey’s tradition of designing the most responsibly engineered lightweight products on the market. In addition to reducing needless weight, strength is actually increased through the use of such trademark Ritchey specialties as Force Directional (FD) technology, proprietary butting and heat treatments, and the use of only the highest quality “spare no expense” materials. ProControl strikes a balance between reduced weight and improved strength, the result of which can greatly improve the performance of a mountain bike. Steering is more accurate and shock absorbing is enhanced.
Ritchey’s ProControl will fit any standard–size or 1-1/8″ oversize mountain bike, which makes improved performance available to thousands of riders without the high end cost of purchasing a new bike. And when you figure ProControl’s cost versus it’s weight benefits and improved front–end agility, the new ProControl system from Ritchey is winning . . . by design.

HANDLEBARS & GRIPS
Establishing standards for handlebars has been one of Tom Ritchey’s endeavors ever since he introduced the original one–piece “Bullmoose” design in 1981. A handlebar is more than a piece of bent aluminum tubing. Ritchey’s designs of previous years have soon become his competitors’ goals. At the same time, Tom is busy in the shop and on the trail designing an even better product. To understand this you need only look at Ritchey’s LATEST bar — the remarkable ProLite “WCS,” a 120 gram special development effort between Tom Ritchey and Easton Aluminum in the U.S.

RITCHEY COMPONENTS
FORCE COMP STEMS
The numerous medals won at the 1990 and 1991 World Championships are just the latest proof that the Force Comp Stem is the strongest, lightest stem available. The Force Comp features unique, butted “supertubing,” made with a proprietary second heat treatment process to allow the use of thinner gauge chromoly. An unbeatable and unmistakable combination is made with trademarked ovalized extension tubing and unparalleled quality construction. Fatigue testing showed the Force Comp to exceed JIS standards by 300%, outperforming all previously tested stems. At just 290 grams (150mm), the trustworthy Force Comp leads in light weight and durability. The butted Force Comp is now also available for high performance road riders. Currently the Shaklee and Subaru road racing teams along with the National Cycling Team claim this stem is the strongest and lightest they’ve ever used!
Force Comp (MOUNTAIN)

SEATPOSTS & SADDLES
Have you ever seen a seatpost bent sideways? They don’t because all the forces are imposed on the fore and aft directions. So Tom Ritchey designed the world’s first and only force directionally butted seatpost. It uses superior strength 2014 series aluminum in the post, but that’s only the beginning. Instead of a bulky cast clamp, the FD post is joined to a super–tough forged, single bolt clamp. Then a special welding process is used to create not only the toughest seatpost available, it’s also the lightest. The 300mm FD seatpost weighs over 15% less than the leading competition. The FD is now available in both mountain bike and road bike sizes, and all are built with the craftsmanship and aesthetics that make Ritchey components the number one choice for serious riders!
Force Directional Seatpost (MOUNTAIN)
It’s tough, butted, light, and has the looks that belong in a showcase. The FD Seatpost is the ultimate in racing posts, and it’s now available in road and off–road lengths as well as in standard and oversize diameters
INTENDED USE ◆ competition and lightweight “project bikes”

Logic Pro Saddle
While most alloy rail saddles are breaking, the new Logic Pro takes a different approach to increasing strength and saving weight using aluminum. We took the same great Logic Racing saddle rails and forged them with the best 7075–T6 aluminum and in the strength sensitive areas increased the vertical area by 180% to resist the impacts of rugged ridding (see figure). At 250 grams, the Logic Pro saddle is light years ahead!

LOGIC BRAKES & CABLE HANGERS
Tom Ritchey has designed a lightweight brakeset that actually helps you go faster. The new Logic Brakeset is a high performance braking system with features top racers demand. Tom starts off with a powerful new medium profile cantilever design, then constructs brakes using the best quality cold–forged alloy available for the design. In addition to using a minimalistic two–position spring design, Logic cantilevers reduce the distance to the fork to eliminate performance–robbing chatter. A specially designed brake pad adjustment hole increases vertical adjustability, offering the best rim/tire versatility. To get maximum performance from Logic Brakes, Tom designed the new Logic Brake Levers. The ergonomically correct three–finger lever features a wedge profile to reduce fatigue, and a special index finger “harbor” to add comfort. Cold–forged for strength, Logic Brake Levers are just the thing to finish off this truly high performance brakeset.

LOGIC CRANKSETS
At last a Logical cure for the common cold–forged crank! Tom Ritchey created this crankset with the serious rider in mind. The Logic Crankset is cold–forged for superior strength, and features an ultra–clean “hidden pin” design for less weight and increased stiffness. The Logic Crankset has a very low “Q–factor,” a feature that makes for efficient and ergonomic pedaling. The left crank arm also receives a unique reinforcement at the axle area to increase strength. Finally, the super duraluminum material is hand polished to a high quality satin finish that’s only found on the highest quality cranks.

HEADSETS & BOTTOM BRACKETS
Upper bearings of headsets don’t wear out, but lower bearings do. That’s because nearly all impact forces work against the lower bearings. The upper bearings work mainly as a keeper. That’s why Tom Ritchey designed the Logic Headsets. Oversized 3/16″ bearings on the bottom increase the strength by substantially increasing the amount of load bearing surface area. To balance the smaller load requirements on the top, Logic uses 1/8″ bearings which also reduce needless weight. The result is a headset that has the strength of an oversize headset while actually reducing the weight of a standard size headset. Another example of Ritchey winning by design.
Logic Comp Headset
You can’t find a stronger, lighter headset! That’s why so many top pros choose the Logic Comp headset for top performance on the road and off.

Current fads to widen bottom brackets aren’t necessary with Ritchey’s new Logic Bottom Brackets. The Logic BB fits a standard 68mm frame shell, while moving the cup–bearing position out to 78mm. This gives you the axle/bearing strength of a wider or oversize bottom bracket without needless extra weight and availability hassles. Through careful design and the use of the highest quality chromoly and ni–chromium materials, Ritchey has developed the lightest and toughest bottom brackets available!
Logic Pro
The Logic Pro is a durable, competition–worthy bottom bracket. It’s strong, light, and provides superb pedaling performance!

LOGIC FORKS
Have you ever seen a fork bent sideways? Tom Ritchey hasn’t. Seeing another opportunity for design improvement, Tom used his proven philosophy of strategic strength–placing and fat trimming to make the Logic Fork. The Logic Fork uses the world’s first Force Directional butted steerer — thicker on the front and back, and thinner on the sides. It’s stronger than conventional steerers where it needs to be, but overall it’s lighter. Then Tom designed big 27mm triple butted fork blades, which make the Logic Fork Track like no other lightweight fork in the world. In fact, the Logic fork carried a Ritchey rider to victory in the 1989 NORBA World Championships. In 1990, half the pro/elite cross–country medals at the World Championships were won with Ritchey Logic Forks. With Logic you get proven performance and proven durability! New for ’92 is the “Prestige” Logic Fork.

TUBING & DROPOUTS
Frame tubes rarely fail in the middle. They usually fail at the ends near the welded joints. This was the original motivation behind Tom Ritchey’s Logic Frame Tubing. Logic tubing is differentially double and triple butted — it thickens at the ends with a shorter and stronger butting. This design lets the tube withstand the concentrated heat of TIG welding and the rigors of front–end abuse. This construction also allows a much longer “thin” area, reducing weight significantly. These Ritchey designed, Tange manufactured tubes allow the building of the lightest chromoly frames in the world (3.8 lbs., 19″ size), frames that are also strong enough to carry pro riders to three of the top six pro/elite medals at the 1990 World Championships. This year Ritchey introduces a full range of new Logic tubing, including mountain, road, and hybrid/cross tubesets.
Logic Tubesets
Tom Ritchey steels the world! Ritchey–designed Logic tubing has proven to be the best performing steel tubing in the world, with the results to prove it: 1989 NORBA World Champion (men’s pro/elite cross country), 1990 Hillclimb Worlds gold medal (men’s pro/elite), 1990 Worlds Cross–Country silver and bronze medals (men’s pro/elite), two 1990 Worlds Cross–Country bronze medals (men’s and women’s pro/elite), and a 1990 Worlds Road silver medal (women’s).
