Abstract: A clutch with an inner rotatable member and an outer rotatable member. A plurality of clutch members are arranged between the inner rotatable member and the outer rotatable member to permit relative rotation of the inner rotatable member with respect to the outer rotatable member in a first direction and restrict relative rotation of the inner rotatable member with respect to the outer rotatable member in a second direction. The clutch members include a wedge portion and an interlocking portion. The wedge portion and the interlocking portion engage with the inner rotatable member and the outer rotatable member to restrict the rotation in the second direction. The wedge portion engages before the interlocking portion.

Abstract: A sprag clutch based freehub system that has an easily swappable free hub portion is provided. The freehub system uses a cassette driver adapter shaft (also referred herein as “driver”) that is positioned within the hub. The cassette driver adapter shaft (driver) and freehub body have a separable interface. This allows for easy interchanging of freehub bodies by the user while not risking contamination or damage to the hub.
