ROTOR - Bottom Bracket UBB 4630 PF30 CERAMIC
You had your choice of any bike in the shop but you made your selection based on potential upgrade options. The Press Fit 4630 will easily accommodate your handpicked rig with its press fit, 46mm diameter with 30mm axle BB shell. 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 Press Fit 4630 is the "yes" component to "Is this compatible with my press fit 46mm diameter BB shell for a 30mm axle?"
