FSA spare part BB30 Wave Spring Washer

Product description

This flexible corrugated washer is designed for use with the BB30 and BB386EVO standard.

Its main task is to provide a gentle lateral preload for the bottom bracket bearings. This effectively limits micro-play, prevents lateral movement of the cranks and helps eliminate unwanted noises (clicking or creaking) when pedaling. At the same time, it protects the bearings from uneven wear.
