Thirty years of commitment to research and innovation yielded the world’s fastest, most advanced cross country race wheels. Bill Shook designed this unique tubeless race wheel system emphasizing
strength, durability and stiffness in a concept Bill calls, “multiplying lightness.” The 26” rim is a whopping 28mm wide x 22mm deep and only 310 grams. Ride a smaller, lighter tire because it spreads out across the rim without sacrificing traction and handling. Our wide Race rims offer improved ground control because the tire is not floating around. Bead barb technology hooks on the tire bead to secure the tires in place without burping. New lighter 14/16 AC Race Round spokes were specially designed for this hand built wheel system. AC test riders raced these wheels all season championing their strength, quick accelerations, solid cornering, fast climbing and descending, and low maintenance. A solid choice for pure speed at full throttle power.
