Rotor BSA30 Track bottom bracket
This minimalist, lightweight, low-drag bottom bracket is designed specifically for use with new Rotor ALDHU 3D track cranks.
Regardless of what your nerdy know-it-all friend told you, this is the only bottom bracket that will work. Yes, really.
Includes installation tool.
⚠️ This will not work with older Rotor Track cranksets having a 24mm axle.
