Wheels MFG T47 A/C BB 30mm Black
Description
T47 threaded BB cups for T47 frames and 30mm diameter spindle 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.
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.

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 29mm DUB 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
