WOLF TOOTH bottom bracket T47 Internal Shimano 24mm black

Product description

The Wolf Tooth T47 External Bottom Bracket (for Shimano 24mm axle) is designed to offer smooth operation, long life, low weight, high speed and easy user serviceability. The all-new design uses custom bearings, seals, bushings and cups to eliminate annoying squeaks and combines superior weather protection with optimized radial bearing compression, precise seating and preload for minimal rolling resistance. This version is designed for Shimano 24mm axle cranks and is available in four color options that coordinate perfectly with other components from the Wolf Tooth Color Shop range.

The bearings in Wolf Tooth bottom brackets have a special custom design. The balls and raceways are made of hardened chrome bearing steel. This has a higher surface hardness than stainless steel, which increases the durability of the raceways and reduces rolling resistance and noise. In addition, the raceways are coated with ACOSUR ZNA, which, after a 500-hour salt spray test, shows the same or higher corrosion resistance than stainless steel. The bearing material used, combined with a sophisticated sealing system and the elimination of metal-to-metal contact, ensures excellent performance in all conditions for the Wolf Tooth bottom bracket.
