The crank transmits your power to the chain and thus to the bike. It carries a large part of the weight of the rider. A distinction is made between 3-piece and 1-piece cranks, with the 1-piece only being considered for younger, lighter riders. The 8-spline crank (3-piece) is placed on the axle and fixed by a bolt. The 48-spline crank (also 3-piece) is put on the axle like this. This is an interference fit, which means the crank must be pressed or carefully hammered onto the axle with pressure.
The bottom bracket must be suitable for the frame ( Mid BB or US BB). In addition, the number of teeth of the axle must match that of the cranks ( 8T or 48T).
