How can I identify my bottom bracket?
If your bike creaks when you pedal hard, if the movement of the crankset is no longer smooth, or if it has become loose, the symptoms are clear: it’s time to replace your bottom bracket. Like all parts of your bike, the bottom bracket and especially its bearings are subject to wear and tear.
Replacing it is a straightforward process if well prepared. The multitude of bearing, bottom bracket, and frame standards may intimidate some. We will try to guide you through this jungle of standards. The bottom bracket is the interface between your crankset and your frame. Therefore, you first need to determine which crankset is supposed to fit which frame.
