Rotor BB1 BSA 68mm Steel Black Bottom Bracket

ROTOR BB1 BB MTB BSA Steel Black
You've decided that your bike's performance features could be enhanced with components selected á la carte — and that you should be able to accomplish this despite the proliferation of numerous bottom bracket "standards" that have created component compatibility issues at your local bike shop. Conventional threaded bottom brackets like your english threaded BB shell shouldn't foil plans to upgrade your ride. ROTOR conceived its Universal Bottom Bracket (UBB) concept to eliminate the complicated bottom bracket/crank compatibility challenge that has increasingly frustrated the mechanics at your LBS.
