American Classic 205 Road Rear Shimano Hub 28 Hole

American Classic 205 Road Rear Shimano Hub 28 Hole

Bill Shook designed the RD 205 hub to achieve four goals, stiff, strong, light and reliable. At 205 grams, it is one of the lightest, quiet riding hubs on the market. The large diameter 17mm axle is stiff and maintains proper bearing alignment under all riding conditions. The flange spacing was designed for optimal dishing. The hub shell supports the bearings as wide as possible for maximum leverage to reduce the load on the bearing and stiffen the hub. The 19mm diameter drive side end cap is made of serrated steel for better grip on the frame. Adjustable bearings and patented sleeve technology for ease of adjustment and improved bearing life. Every part of the RD 205 has been engineered and thoroughly tested for fast, reliable racing and riding.STEEL FACE CASSETTE BODYBill Shooks strong suit is finding answers to industry wide problems. Aluminum cassette bodies are damaged by the individual cassette cogs, and from loose fitting shimano cassettes. Bill Shooks ingenious answer is his latest patent applied design, the steel faced cassette body. All our shimano style cassette bodies are now equipped with the proven steel face on the splines so that the body will not be damaged by the cassette. Each steel insert is securely dovetailed in place by hand with Bills specially designed insert tooling. Steel is harder than aluminum which protects the softer aluminum from being gouged by the cassette. You get the best of both worlds, a light weight aluminum body with the protection of a steel surface. The steel faced cassette will prolong the life of your American Classic hub and make changing cassettes easier. A brilliantly simple solution to an annoying problem. It is Bill Shooks attention to detail that make American Classics wheels better than the rest.SIX PAWL CAM ACTUATED ENGAGEMENT SYSTEMOne of Bill Shooks most important designs is his patented Six Pawl Cam Actuated Engagement System found in our hubs. All six oversized pawls engage in unison whenever drive torque is applied. No other multiple pawl system on the market can ensure that all pawls are engaged at the same time. The cam plate powers the pawls into engagement simultaneously. There are new expanded cupped engagement pockets in the cam plate for improved contact. The secondary ratchet system does the coasting quietly and forces engagement of the large pawls only for drive torque transfer. The cassette body has 24 ratchet teeth for quick engagement with the pawls. Each pawl is made from super strong tool steel and has double tips for 12 points of engagement to work in conjunction with the 24 ratchet teeth. The one piece forged 7075 aluminum cassette body is hard anodized and is topped with Bills latest steel face body design.
