Wolf Tooth T47 External Bottom Bracket, 24 mm, Black
Wolf Tooth T47 External bottom brackets are designed for smooth operation, maximum durability, and easy serviceability. The unique design utilizes custom bearings, seals, and polymer sleeves that effectively eliminate annoying creaking. The system combines top-notch weather protection with optimized bearing compression for minimal rolling resistance. This variant is designed for T47 frames where the bearings are located in cups outside the frame.
The premium ACOSUR ZNA coated bearings have balls and races made of hardened chrome steel, which has a higher surface hardness than stainless steel. This ensures longer life and quieter operation. Thanks to the special ACOSUR ZNA coating, the bearings are more resistant to corrosion. Combined with sophisticated sealing and elimination of metal-to-metal contact, these bottom brackets provide top performance in any conditions.
