Rotor Press-Fit 4630 Road Bottom Bracket
Press fit Bottom Bracket compatible with 30mm axle chainsets.
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. (Great News!!) The Press Fit 4630 is the "yes" component to "Is this compatible with my press fit 46mm diameter BB shell for a 30mm axle?"
