The Wheels Manufacturing T47 Inboard Bottom Bracket threads directly into T47 frames and houses bearings internally within the machined aluminum cups — no outboard bearing cups or adapters needed. The wider T47 shell accepts a broad range of shell widths from 68mm to 132mm, making it highly versatile across road, gravel, and mountain applications. Designed for SRAM DUB 29mm cranksets, with high-quality Enduro ABEC-3 bearings that are easily serviced or replaced.
