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*
Bottom Bracket Shell Width: 61mm* to 83mm
Bottom Bracket Shell I.D.: 46mm
Over Bearing Width: 89mm in 68mm wide shell
Crank Spindle Diameter: 30mm

T47 threaded BB cups for T47 frames and 29mm diameter spindle SRAM DUB compatible cranks. Cups have internal bearings, and can be used in BB shells with widths from 68mm to 132mm. Machined aluminum cups thread together directly into a T47 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.
T47 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.

Wolf Tooth BSA Bottom Brackets are engineered to be smooth, durable, lightweight, fast, and user-serviceable. The ground-up design features custom bearings, seals, bushings, and cups, which eliminate creaking and balance best-in-class weather sealing with optimized bearing radial compression, alignment, and preload for low drag.
The bearings in Wolf Tooth Bottom Brackets feature a custom design. The balls and race are made from a hardened chrome bearing steel. This has a higher surface hardness than stainless, which improves the durability of bearing races and reduces spinning resistance and noise. An ACOSUR ZNA coating has also been applied to the race to provide corrosion resistance that is equal to or better than stainless steel after a 500-hour saltwater test. Bearing material paired with an extensive sealing system and the elimination of metal-on-metal contact means Wolf Tooth Bottom Brackets have superior performance in all conditions.
- Compatible with 24mm spindle cranksets
- Adjustable-width sleeve fits 68mm - 73mm BSA bottom bracket shells
- Best-in-class weather sealing protects bearings from water, mud, and debris
- Custom polymer spindle bushings eliminate creaking
