Wolf Tooth "T47i" MTB Bottom Bracket

The Wolf Tooth "T47i" MTB Bottom Bracket is the Wolf Tooth bottom bracket for T47 internal shells from 85.5 to 92 mm wide, where the bearings sit inside the shell and only the tool flange is outside, machined and assembled in Minnesota. The bearings are an in-house design: balls and races of hardened chrome steel (AISI 52100), harder than stainless and lower in drag, with an ACOSUR ZNA coating that protects against corrosion at least as well as stainless in a 500 hour salt water test; Wolf Tooth backs that with a lifetime warranty. Seals and polymer spindle bushings keep water and mud out and stop creaking, the adjustable inner sleeve covers 85.5 to 92 mm. For 29 mm (SRAM DUB) and 30 mm spindles, installed with the 52-16 tool, in the Wolf Tooth colours.
