WOLF TOOTH bottom bracket T47 Internal Sram 29mm black

Product description

Wolf Tooth T47 Internal bottom brackets are designed with smoothness, durability, light weight and ease of serviceability in mind. Our ground-up design uses custom bearings, seals, bushings and cups to eliminate annoying squeaks. The system combines best-in-class weather protection with optimized radial bearing compression and precise preload for minimal drag. Available for 24mm (Shimano), 29mm (DUB) and 30mm axles, the brackets come in four colors to coordinate with other Wolf Tooth Color Shop accessories.

Premium bearings with a unique finish Wolf Tooth bearings use a specific design where the balls and races are made of hardened chrome bearing steel. This has a higher surface hardness than stainless steel, which increases the life of the races and reduces rolling resistance and noise. In addition, the bearing races are coated with ACOSUR ZNA, which provides corrosion resistance comparable to or better than stainless steel (verified by a 500-hour salt bath test). By eliminating metal-to-metal contact and sophisticated sealing, these compositions deliver top performance in any conditions.
