The new Reverse Single-Speed sprockets can be mounted on Shimano hubs and all conventional standard freewheel bodies. Thanks to the extra wide mounting flange, the freewheel of the hub is protected from notches and a balanced power transmission is guaranteed. Thus the Reverse Single-Speed Kit provides optimum protection even with aluminium freewheels.
