BlackBearing B5 T47 86/92 30mm
Description
The Blackbearing bottom bracket range has been specifically developed to withstand the most extreme conditions.
The BBlock technology (built in 2 threadable parts) allows a better alignment of the casing in its assembly offering several advantages:
- minimizes possible cracks
- greater protection to the bearing extending its useful life
- an easier replacement of the bearing.

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 29mm 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
- Installation and removal with standard 46-12 spline tool
- Replacement parts available
- Engineered, machined, and assembled at Wolf Tooth HQ in Minnesota, USA
- Lifetime warranty on the bearings
Bottom brackets ship with the following shell and spindle spacers:
