This is the genuine SRAM BB30 bearing and seal kit to replace worn-out BB30 bottom bracket bearings. 

MODEL ID: BB-BB30-A1

The Bicycle Depot Technical Top Tip: BB30 bottom brackets are prone to producing noises under load - this may be due to very minor frame manufacturing defects causing bearings to be slightly misaligned. Misaligned bearings may wear quickly and may produce clicking noises or similar. Please be aware that fitting new bottom bracket bearings may not resolve these issues.
