The time proven Disc 225 hub is stiff, strong,
light and reliable. The strong, patented 6 pawl cam actuated engagement system
handles the constant re-accelerations of XC. The large diameter 17mm axle is
stiff. The big 19mm diameter serrated steel drive side end cap grips the frame.
The flange spacing was designed for optimal dishing which is the balance point
between wheel triangulation, spoke tension and lateral stiffness. Built-in stand
offs on the disc mounts allow the rotor to mount flat and prevent warping while
tightening. The hub shell supports the bearings as wide as possible for maximum
leverage, to reduce the load on the bearings and stiffen the hub. This is one
fast, quiet riding hub at 225 grams.

American Classic Six Pawl Cam Actuated Engagement
System
One of Bill Shook’s 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 and forces engagement of
the large pawls only for drive torque transfer. Each pawl is made from super
strong tool steel and has double tips for 12 points of engagement. The cassette
body has 24 ratchet teeth for engagement with the pawls. The one piece forged
7075 aluminum cassette body is hard anodized and is topped with Bill’s latest
steel face body design.
Cassette Body
There has been a universal problem in the
bike industry. Aluminum cassette bodies are damaged by the individual cassette
cogs, and from loose fitting shimano 10 speed cassettes. Bill Shook found an
ingenious solution to this problem with his latest design, the steel faced
cassette body. All our new shimano style cassette bodies are now equipped with
the steel face on the splines so that the body will not be damaged by the
cassette. Each steel insert is dovetailed in place. 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 Shook’s
attention to detail that make American Classic’s wheels
better than the rest.
