Wheels Mfg PF30-Outboard A/C BB 30mm
Description
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. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear.
** 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 Angular contact
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
Tool Pattern: 48.5mm x 16 notch
* Specialized Carbon OSBB with 61mm shell width will need additional 3.5mm cup spacers.

Wolf Tooth T47 Internal 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 85.5mm - 92mm T47 Internal bottom bracket shells
- Best-in-class weather sealing protects bearings from water, mud, and debris
- Custom polymer spindle bushings eliminate creaking
- Installation and removal with standard 52-16 spline tool or BBS5216
- Replacement parts available

** FIT KIT REQUIRED FOR USE **
ThreadFit 30 comes with a Center Sleeve for 73mm BB shell. For 68mm shell - sleeve is required(included in Fit Kit #2 for DUB Road cranks).
ThreadFit 30 bottom bracket is silky smooth and long-lasting thanks to legendary, angular-contact bearings. They actually get faster over time as their contact surfaces wear, because they are build to ultra-tight aerospace tolerances, using machined, Delrin-spindle sleeves to create a perfect, and precise fit between cranks and frame. That’s where the low drag and butter smooth feel come from.
You want this bottom bracket because it offers super low drag. You want this bottom bracket, because it can be opened, cleaned and repacked for years of faithful service. You want this bottom bracket, because you don’t want to think an awful lot about your bottom bracket.
