ABSTRACT:
A bicycle hub shell has an axial bore with a first end portion, a second end portion and an internal wall which confines the axial bore into a first section adjacent to the first end portion and a second section adjacent to the second end portion and narrower than the first section. A first bearing-receiver is disposed in the first end portion of the hub shell and has an enlarged head to receive a bearing therein and an internally threaded connecting tube which extends into the first section. A cylinder drive has a head portion disposed partially in the second end portion of the axial bore, an externally threaded end portion which is spaced axially from the head portion, and a plurality of ratchet pawls exposed exteriorly from the second end portion of the axial bore. The head portion of the cylinder drive further has an externally threaded and axially extending tube extension projecting into the first section of the axial bore and engaging the connecting tube of the first bearing-receiver. A sprocket carrier is supported around and engages the ratchet pawls of the same so that the cylinder drive is co-rotatable with the hub shell.
