HOW TO INSTALL THE BOTTOM BRACKET

A good bottom bracket also needs proper installation. First, clean the frame shell threads with clean rag, then heavily grease them or apply light thread lock. Then use a traditional splined bottom bracket tool to tighten the bottom bracket to 50-70 nm. If you do not follow these steps, the bottom bracket could be likely to produce strange noise and been prematurely worn out.
