A bicycle crank axle (59) is adapted to be rotatably supported within a bottom bracket (33) of a bicycle frame. The crank axle (59) comprises an axle body (348) having a first and a second end portion (350,354), and a flange (366) extending radially outwardly from one of the first and second end portions (350,354) of the axle body (348), wherein the flange (366) is dimensioned and positioned to be located externally of the bottom bracket (33) so as to abut against a laterally outer side surface of a bicycle crank arm (60A) to prevent the crank arm (60A) from moving axially outwardly. |
