摘要

A bicycle includes a frame, a front and rear wheel and a crank assembly. The frame includes chainstays and a bottom bracket having a center and which rotationally receives the crank assembly. The crank assembly includes a chain ring having a radius between the bottom bracket center and a circumferential edge. The chainstays are connected to the bottom bracket at a first end and rotationally receive the rear wheel at a second end. The chainstay defines a cutout sized to receive a portion of a circumferential edge of the chain ring.
