Wolf Tooth T47 Internal bottom brackets are designed with an emphasis on smooth operation, durability, low weight, and easy serviceability. Their proprietary, ground-up design uses special bearings, seals, bushings, and cups that eliminate annoying squeaking. The system combines top-notch weather protection with optimized radial bearing compression and precise preload for minimal drag. Wolf Tooth bearings use a specific design where both the balls and raceways are made of hardened chrome bearing steel. It has a higher surface hardness than stainless steel, which increases the life of the tracks and reduces rolling resistance and noise. Additionally, the bearing races are coated with ACOSUR ZNA, which provides corrosion resistance comparable to or better than stainless steel, as verified by a 500-hour salt spray test. By eliminating metal-to-metal contact and using a sophisticated seal, these compounds deliver top performance in any condition.

  • Wide compatibility for cranks with 29 mm DUB axle
  • The inner cap fits T47 Internal center sockets with a width of 85.5 mm to 92 mm
  • Maximum bearing protection against water, mud and dirt
  • Quiet operation thanks to special polymer axle bushings that eliminate metal-to-metal contact
  • The bearings are located inside the frame with an external flange for a standard 52-16 tool
  • Lifetime warranty on bearings
  • Easy availability of spare parts and service manuals (Right to Repair)
  • Designed, machined and assembled in the USA
