FAQs

What is the difference between threaded and press fit bottom brackets?

Threaded bottom brackets screw directly into the frame’s bottom bracket shell, while press fit bottom brackets are pressed into the shell without threads. Threaded systems are generally easier to service, while press fit systems save weight and allow larger shell diameters.

How do I know which bottom bracket I need?

You need to confirm 2 things: your frame’s bottom bracket shell standard (e.g. BSA, BB86, PF30) and your crankset compatibility (Shimano, SRAM DUB, etc.). These specifications determine which bottom bracket will fit correctly.

When should I replace a bottom bracket?

If you experience creaking, rough rotation or side-to-side play in the crankset, the bearings may be worn and require replacement.
