Rotor BSA bottom bracket 30 with BSA thread. These 30 mm outer bearings make it possible to mount a BB30 crankset in a traditional 68mm BSA (English thread) bottom bracket! Cups have a large diameter compared to Shimano/FSA/Sram cups, so this tool is required.
BSA 30 BB is only compatible with:
• Rotor 3D +
• Sram S900 / S975
• FSA BB386EVO
Not suitable for:
Specialized FACT cranks, SRAM Red, Force, Rival, Apex, and most FSA cranks.
