Wolf Tooth T47 Internal Bottom Brackets are engineered to be smooth, durable, lightweight, fast, and user-serviceable. Our 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, 29mm DUB, and 30mm 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.
Bottom brackets ship with the following shell and spindle spacers:
Weights: 24mm • 103g | 29mm • 96g | 30mm • 91g
Material: 6061-T6 Aluminum, Glass-filled Nylon, NBR, EPDM, Urethane, Bearing ball material is AISI 52100 chrome bearing steel hardened to Rc 61-66, Bearing race material is AISI 52100 chrome bearing steel hardened to Rc 60-65
