Crankset standard FSA MegaExo Does your bike creak when you press hard on the pedals, has the crankset movement lost its smoothness 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 could discourage some. We will try to guide you through this jungle of standards. The bottom bracket is the interface between your bottom bracket and your frame, so the first thing to do is to identify which bottom bracket you want to fit in which frame?
