This bottom bracket adapter allows the use of SRAM DUB cranksets with BB86/92 frames, which typically have a 41mm shell inner diameter. It features flanged, double-row stainless steel bearings, specifically designed to fit the 29mm DUB spindle within this tight frame shell, providing a stable and lasting solution.
The bearings are made with 440C stainless steel balls and races for superior corrosion resistance, suitable for wet conditions or frequent bike washing. The kit includes seals for bearing protection, a center sleeve, and spacers for precise chain line tuning, along with an aluminum preload adjuster.
