Wolf Tooth T47 External 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 T47 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 44-16 (24mm) and 46-12 (29mm DUB, 30mm) spline bottom bracket tools
