Wolf Tooth Components T47 Internal Bottom Bracket

Description

Best In Class Sealing, No Sacrifice in Speed

Wolf Tooth T47 Internal Bottom Brackets are engineered to be smooth, durable, lightweight, fast, and user-serviceable. Their 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. They're available for 24mm Shimano and 29mm DUB spindle diameters for maximum compatibility, and four colors to match your other Wolf Tooth Color Shop components.

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.
