Does your bike crack when you press hard on the pedals, has the movement of the crankset lost its fluidity or has it become loose? 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 will 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 toidentify which crankset you want to fit in which frame ?
