Abstract
A crank arm comprises an arm body, an axle fastener, and a biasing element. The arm body includes a crank-axle receiving opening and an axle-fastener receiving opening. The axle-fastener receiving opening has a second opening axis. The axle-fastener receiving opening is partly in communication with the crank-axle receiving opening by a connection opening. The axle fastener includes a fastener body having a splined portion. The splined portion is configured to engage with the splined end of the crank axle in a mounted state where the crank arm is mounted to the crank axle. The biasing element is configured to bias the axle fastener in a biasing direction parallel to the second opening axis.
