UBB 4630 Bottom Bracket
As much as we'd love to only buy frames with threaded bottom bracket shells, the reality of the market often leaves us opting for press fit shell to get the exact ride we're looking for. When that happens, it's comforting to know that Rotor's UBB Rotor UBB 4630 Bottom Bracket is there to alleviate the creaking that so commonly plagues press fit systems. Its internal sleeve threads together to lock in perfect alignment and provide a precisely solid interface between the cranks and frame.
