Stock Code:WMBB-PF30-OUT-30MM
By popular demand, we've added this PF30 with outboard bearing BB for use with 30mm spindle cranksets when used in PF30 frames. A great choice for use with RaceFace Cinch cranks. The two machined aluminum cups thread together keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.
** Note: Spindle length must be 103mm or longer when used in a 68mm wide shell, 108mm or longer when used in a 73mm wide shell.
Bearings: Enduro ABEC-3
Bottom Bracket/Frame Interface: PF30, Specialized Carbon OSBB*

Stock Code:WMBB-BB-T47A-29MM
T47a (asymmetrical) threaded BB cups for T47a frames and 29mm diameter spindle compatible cranks. Cups have internal bearings, and can be used in BB shells with widths from 77.5 - 79mm. Machined aluminum cups thread together directly into a Cervelo, Factor and Felt T47a BB shell. Bearings are easily serviced or replaced. Includes sleeve to fit between cups for added protection from dirt and grime, and also keeps your internal wires and hoses from rubbing on the crank spindle. T47a BB cups are similar to standard BSA threaded cups in that the drive side cup is left-hand thread and the non-drive side cup is right-hand thread. Use a quality grease when installing in steel or aluminum BB shells, and an anti-seize compound compatible with titanium BB shells.
