ABSTRACT:
In a crankshaft operated brake actuating device for bicycles, a brake operating lever extends through the lower bracket from a yoke contacting the crankshaft. A light weight spring clutch transmits torque from the crankshaft to the lever upon back pedalling, and reaction from the torque causes the lever to tilt and engage a strap clutch locking the lever to the crankshaft as the braking forces are increased.
