Abstract:
A crankset comprises an axle assembly, a removably attached crankarm, and a non-removably attached crankarm. The removably attached crankarm is attached at a first end portion thereof to a first end portion of the axle assembly. The non-removably attached crankarm is attached at a first end portion thereof to a second end portion of the axle assembly. Each one of the crankarms has a plurality of longitudinal holes therein extending between the first and second end portions thereof. The longitudinal holes each extend through an end face of a respective one of the crankarms at the first end portion thereof. The removably attached crankarm is bent inwardly toward the second end portion of the axle assembly after the longitudinal holes are formed therein. Only one of the longitudinal holes of the removably attached crankarm intersects an axle fastener engagement hole that extends through the first end portion of the removably attached crankarm.
