Rotor BSA 30mm Ceramic 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 colour with steel bearings or red with Enduro Grade5 Ceramic bearings.

The steel option offers a light and elegant bottom bracket at a very competitive price while the ceramic bearing options are ideal for those looking to shed every possible gram while at the same time acquiring an incredibly smooth bottom bracket. Both versions are available for road (BSA only) as well as MTB use. The ceramic versions come in at an incredible 86g, while the steels 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.



  • Steel (black cups) 96g,
  • Ceramic (red cups) 86g.
  • Lathe and CNC T6 heat treated 7075 Aluminium.
  • Silicone seals offer low drag, quality-bearing protection.
  • Includes BB spanner
