Bicycle shaft component

摘要

A bicycle shaft component includes an outer tubular member (30) and an inner member (32) non-movably attached to the outer member. The outer tubular member includes a first end portion (42) and a second end portion (44) with an interior longitudinal passageway (46) extending between the first and second end portions. The interior longitudinal passageway (46) has a longitudinal center axis (X) extending through it. The inner member (32) is non-movably attached to the outer tubular member (30) within the interior longitudinal passageway (46). The outer tubular member (30) is constructed of a first material having a first specific gravity and the inner member (32) is constructed of a second material having a second specific gravity that is lower than the first specific gravity of the first material.
