Description

ROTOR UBB 4630 Bottom Bracket

The ROTOR UBB 4630 Bottom Bracket adapts any PF30, BBRight or 386 EVO bottom bracket shell to fit a 30 mm diameter crank spindle. However, what is unique about ROTOR’s UBB, is that it features external bearings and uses a threaded sleeve to lock the bottom bracket cups in place. This offers several advantages over a more traditional press fit bottom bracket. The ROTOR UBB helps provide a uniform, smooth spin to the crankset, it helps eliminate any unwanted noises and creaks; it works to improve bearing life; and the external location of the bearing results in increased shell stiffness.
