ROTOR BB BSA30 68/73MM BLACK THREADED

ROTOR BSA 30 Bottom Bracket

Rotor’s BSA30 bottom bracket allows the installation of our 3D+ BB30 cranks into a standard, threaded bottom-bracket. The BSA30 is available in black color with steel bearings. The steel option offers a light and elegant bottom bracket at a very competitive price. This version is for road (BSA only) as well as MTB use. The steel Bearing BB comes in at 96g (depending on size and the number of spacers needed, an extra 3 to 9 grams may be added).

The BSA30 is not compatible with BB89 or BB90 frames.
