ABSTRACT:
A bicycle pedal crank bearing system has a hollow axle within which expandable cone shaped discs are flattened so as to expand radially outward and expand the axle into locking engagement with a thrust sleeve surrounding the axle. Since the thrust sleeve can not move axially relative to the bearing, the axle is likewise axially positioned, but is still free to rotate. The chain path is, thus, easily aligned and access to the bearings for maintenance is made easier.
