Patent ID: 8142312

Claim:
A bicycle component comprising: a base member; and an axle including a base supporting part supporting the base member for pivoting about a center axis of the axle and a base attaching part projecting outwardly of the base member for fixed attachment to a bicycle frame, the base supporting part and the base attaching part including overlapping portions that overlap by a prescribed axial amount in an axial direction of the axle to define a coupling interface between the overlapping portions of the base supporting part and the base attaching part in which either a fixing element is disposed between the overlapping portions of the base supporting part and the base attaching part or one of the base supporting part and the base attaching part is deformed with an interference fit, the base supporting part being formed of a first material with a first specific gravity and the base attaching part being formed of a second material with a second specific gravity that is higher than the first specific gravity.
