Truvativ Bottom bracket adapter American-to-Euro

SRAM BMX US to Europe bottom bracket adapter

Does your bike creak when you press hard on the pedals, has the bottom bracket movement lost its smoothness or 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 ?
