The present invention is directed to a bicycle crank axle adapted to be rotatably supported within a bottom bracket and supported bicycle crank arm. The crank axle comprises an axle body having a plurality of first splines disposed at a first end portion of the axle body and a plurality of second splines disposed at the second end portion of the axle body. The crank axle also comprises a projection extending radially outward from the first end portion of the axle body. The projection is adapted to abut against a lateral outer surface of the bicycle crank arm to prevent the crank arm from moving axially outwardly. The first splines extend radially outwardly from an outer peripheral surface of the axle body and are suitable for engaging a splined inner peripheral surface of a mounting boss of the bicycle crank arm. The second splines do not extend radially outwardly relative to the outer peripheral surface of the axle body.
