23% weight saving over previous model
A complete redesign of the freehub and drive mechanism account for most of the weight savings. A smaller set of grouped sprags interface with a narrower steel contact patch on the drive axle. The reduction in the amount of stainless steel, resulted in significant weight savings. The freehub itself no longer rests on a steel axle, but utilizes a keyed interface. Once again, less steel means more weight savings.
