Abstract
A bicycle multi-gear cassette mountable to a wheel hub driver mechanism that includes truncated conical shell having a first opening proximate a small shell base and a second opening proximate a large shell base. The openings are coaxial with an axis of the shell. A plurality of toothed sprockets having different numbers of teeth are disposed on the shell and extend radially of the central axis. A torque load transmitting profile is configured on the shell proximate one of the small and large shell bases. A radial load transmitting profile is configured on the shell proximate one of the small and large shell bases. The shell, sprockets, and the load transmitting profiles embody a single piece. The torque load transmitting profile forms a featureless contact surface for frictional engagement with the hub driver mechanism.
