Thirty years of commitment to research and innovation yielded the world’s fastest, most advanced cross country race wheels in 26, 29 and new 650B sizes. Bill Shook designed this unique tubeless race wheel system emphasizing strength, durability and stiffness in a concept Bill calls, “multiplying lightness.” These rims are a whopping 28mm wide x 22mm deep. Ride a smaller, lighter tyre because it spreads out across the rim without sacrificing traction and handling. Our wide Race rims offer improved ground control because the tyre is not floating around. Bead barb technology hooks on the tyre bead to secure the tyres in place without burping. Lighter 14/16 AC Race Round spokes were specially designed for this hand built wheel system. Dominating at the races this season, our racers prized their speed, quick accelerations, decisive cornering, nimble climbing, speedy descents, and low maintenance. A solid choice for pure speed at full throttle power. When seconds count in the relentless pursuit to win, our MTB Race Tubeless wheels deliver the ultimate technological advantage.
Wide rims improve cycle performance.
Everybody is talking about wider rims for both road and mountain bike. What does it really mean for you, the rider? There are a few wide rim profiles on the market but they are either heavy, or too light and flexy. Bill Shook used his mathematical abilities to design our revolutionary wide rims, attaining the goal of being light, stiff, strong, aerodynamic and wide, all in one rim. To start, wide rims mean riding lighter, smaller performance tyres with cushiony, high air volume and firm surface grip. Larger width tyres offer more air volume but they are heavy with a sluggish ride quality. The desired combined wheel and tyre qualities are achieved by stretching out the smaller tyre casing on a wide rim and effectively making the tyre bigger. Also, smaller tyres on wide rims reduce tyre roll on the rims. With a narrow rim and a wide tyre, the rim floats from side to side on the tyre. Using a wider rim with a smaller tyre minimises float for improved handling, confidence and control. The rim is lower weight at the extreme outer edge of the wheel decreasing rolling resistance and boosting speed. Our wider, lighter rims translate into crisp accelerations, firm ground control, faster rolling on the flats and decisive handling for the extra edge needed by competitive athletes.
