SRAM DUB PressFit MTB Bottom Bracket 89.5/92

What Is It?

The SRAM DUB PressFit MTB Bottom Bracket is a press-fit bottom bracket designed for SRAM DUB cranksets and MTB frames using compatible 89.5mm or 92mm PressFit bottom-bracket shells.

It uses SRAM's DUB system, which employs an oversized spindle designed to provide broad crankset compatibility while improving durability and protection from the elements. The bearing cups press directly into the frame rather than threading into it.
