Rotor BSA 30mm Steel Bottom Bracket
Created to enable you to run Rotor 3D+ BB30 Chainsets in frames that have threaded bottom bracket shells, this elegant bottom bracket is low in weight and spins freely on its steel ball bearings. The benefit of this design is that you can enjoy the added stiffness of a chainset with a larger 30mm spindle, but still have the larger and more durable bearings of an external bottom bracket.
Please Note: The BSA30 is not compatible with BB89 or BB90 frames.
Features:
- BSA 30 for BSA (English thread) frame
- Lathe and CNC T6 heat treated 7075 Aluminium
- Silicone seals offer low drag, quality-bearing protection
- For use with BB30 type chainsets with 30mm spindles only
- Part Number: C04-014-01010-0
- Weight: Steel (black cups) 96g
