Does your bike creak when you press hard on the pedals, or 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.
Replacing it is a simple operation if well prepared, although the multiplication of bearing, bottom bracket and frame standards may discourage some. We'll 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?
