The SRAM DUB PressFit is a press in bottom bracket for BB89.5 and BB92 mountain frames and SRAM DUB cranks.

What it's for

Use it to install a DUB crankset on a PressFit 89.5 or 92 mm mountain bike frame, or to replace a worn DUB PressFit bottom bracket.

How it works

DUB: one oversized crank spindle that fits every bottom bracket standard. SRAM designed the spindle, bearings, crank, and chainring as one system.

Gutter Seal: a seal design that keeps water and grit out of the bearings with low drag.

Sealed cartridge bearings sit in cups outside or inside the frame shell, depending on the standard.

Compatibility

• Fits: PressFit shells, 89.5 or 92 mm wide
• Crankset: SRAM DUB MTB
• Does not fit: threaded (BSA) shells, PF30, BB30
• How to check yours: a PressFit shell is smooth inside with no threads. Measure the shell width

Setup and installation

• Press in with a bottom bracket press. Do not hammer the cups in
• Follow SRAM's DUB Cranksets and Bottom Brackets user manual
