This press-in solution allows SRAM DUB cranks to be installed directly into BB86/92 framesets. With the shell’s limited 41mm inner diameter, a specialized design is required to accommodate the 29mm BB spindle. By using flanged double-row bearings pressed directly into the BB shell, contact area is maximized by doubling the number of balls per side, providing a durable, long-lasting solution in this tight space.
This bottom bracket features flanged, double-row bearings with anti-corrosion Black Oxide/Magnetite treated 52100 high-carbon chromium steel races paired with Grade 10 balls. The Black Oxide coating adds extra corrosion resistance for extended, worry-free performance. The kit also includes seals to protect the bearings from dirt and moisture, as well as a selection of spacers to fine-tune your chainline.
