What is the SRAM DUB PressFit Bottom Bracket BB89.5/BB92 for?

The SRAM DUB PressFit Bottom Bracket BB89.5/BB92 is designed for mountain bike frames with an 89mm or 92mm PressFit shell, the most common PressFit MTB shell standard. The DUB system's oversized spindle delivers superior crankarm compatibility, excellent element protection, and long-lasting bearing performance in trail conditions. The PressFit design presses directly into the frame shell. Compatible with all SRAM DUB MTB cranksets for standard chainline spacing.

BB89.5/BB92 PressFit is found on a wide range of mountain bike frames. Confirm your frame uses an 89mm or 92mm PressFit shell (not threaded) and your crankset is standard DUB MTB before ordering. For Boost, SuperBoost+, or other chainline variants, see the corresponding DUB PressFit options.

FAQ

What is BB89.5/BB92 and how do I know if my frame uses it?

BB89.5/BB92 is a press-fit standard with 89mm or 92mm shell width and a 41mm inner diameter. It is the most common PressFit shell on mountain bike frames. This single unit fits both 89mm and 92mm widths.

What tools are needed for installation?

A press-fit BB installation tool is required. Never drive cups in with a hammer. Press-fit cups must be installed squarely and evenly to avoid creaking and premature bearing wear.

Is this compatible with Boost or SuperBoost+ cranksets?

This is for standard DUB MTB cranksets only. For Boost or SuperBoost+ chainline requirements, see the corresponding DUB PressFit Boost or SuperBoost+ options.

Best For
