ROTOR BB1 BB Road ITA 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 spawn of deviant bottom bracket "standards" that have created component compatibility issues at your local bike shop. Conventional threaded bottom brackets like your Italian-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. The BB1 ITA is the "yes" component to "Is this compatible with my Italian-threaded BB shell with a 24mm axle?"
