C-Bear BB PF30A Bottom Bracket - 30mm
Silent. Speed. Performance
To eliminate creaking, all C-Bear Bottom Brackets are CNC-machined from high-grade aluminium for a precision fit in your frame. C-Bear will help you avoid unnecessary add-ons - adapters, shims, rings, clips, spacers, glue. Just press in and voila: no creak, no play, no noise! All bearings are fully ceramic for smooth motion, with the aim of maximizing transfer of pedal power to speed.
Introduced by Cannondale, PF30A is used for frames with a non-standard bottom bracket shell width of 73mm (as opposed to 68mm standard for road frames). The "A" stands for Asymmetric - PF30A adds 5mm to the non-drive side of the BB shell but does not change the pedal stance width of a PF30 BB in most cases.
