The RaceFace BSA CINCH is a threaded bottom bracket for 68 and 73 mm BSA shells and 30 mm spindle cranks, including RaceFace CINCH cranks.

What it's for

Use it to install a RaceFace CINCH 30 mm crankset on a threaded frame, or to replace a worn bottom bracket.

How it works

6806 bearings packed with waterproof grease sit in machined alloy cups.

Wiper seals and an inner plastic sleeve keep water and grit out.
