Rotor BB UBB 4630 BBRIGHT-steel Bottom Bracket

Rotor BB UBB 4630 BBRIGHT-steel Bottom Bracket

The UBB4630 for the BBRight standard bottom bracket uses a threaded sleeve to connect both bearing cups. This connection reduces the loads that typically act on the press-fit sleeves. Dimensional tolerances of the lower shell can be compensated, resulting in better parallel alignment of the bearings and smoother crank rotation with reduced noise. External bearing cups further increase rigidity. Better bearing-to-shell fit prevents bearing overload and extends bearing life. The internal sleeve also protects against cable or electronics damage, as there can be no contact with rotating parts.
