crankarm
Bike pedal lever
A crankarm is the lever that connects a bicycle pedal to the central axle, converting the rider's leg motion into rotation.
Crankarms come in pairs, offset 180 degrees, and vary in length to suit different leg lengths and riding styles: I upgraded to longer crankarms for better leverage on climbs.
