Does your bike creak when you press hard on the pedals, has the crankset movement lost its smoothness or become sloppy? The symptoms are clear: it's time to change your bottom bracket. Like all the parts that make up your bike, the bottom bracket and especially its bearings are subject to wear.
Its replacement is a simple operation if it is well prepared, indeed the multiplication of the standards of bearings, bottom bracket and frame could discourage some. We will try to guide you through this jungle of standards. The bottom bracket is the interface between your crankset and your frame, so the first thing to do is to identify which crankset you want to fit into which frame?

We advise you to disassemble your original box to measure precisely the dimensions of the bottom bracket of your frame.
This compatibility is given as an indication, there are also "adapters" boxes which allow to mix the standards.
