Rotor BB30 42mm Bottom Bracket Ceramic Bearings

The all new ROTOR BB30 bearing kit is the ultimate adapter to your BB30 frame. The new BB30 bearings allows you to stop worrying about what cranks fit your bike and just put them on. If youve been brand-loyal since the F700 debuted in the 1996 Olympics - or maybe your frame selection reflects your appreciation for fine craftsmanship. Whichever it is, you can have it both ways with the BB30 bearing kit for frames utilizing the BB30 system. 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 BB30 bearing kit is the "yes" component to "Is this compatible with my BB30 frame?"
