Kogel Bearings PF30 - 386 EVO / Cinch - Cross SealsThis bottom bracket fits most 30mm crank sets on a PF30A frame. PF30A is an asymmetric bottom bracket found on Cannondale carbon frames: SuperSix Evo, SystemSix and Slice. Just make sure the spindle is not too short, like BB30 crank sets from years past. To install a Cannondale crank on any of these bikes, choose a standard PF30 bottom bracket. Cross Seals
