SRAM PressFit GXP MTB BB92 Bottom Bracket
What Is It?
The SRAM PressFit GXP MTB BB92 is a press-fit bottom bracket designed for SRAM GXP cranksets and MTB frames with a PF92 bottom-bracket shell. Instead of threading into the frame, the bearing cups are pressed directly into the frame's bottom-bracket shell.
It uses SRAM's GXP system with a 24mm spindle diameter and is designed to provide smooth crank rotation with sealed bearings. SRAM identifies the BB-PFGXP-A1 as compatible with PF92 as well as several other PressFit shell standards.

Benefits
- Smooth crank rotation: Sealed bearings provide consistent operation.
- PressFit installation: Cups press directly into the frame rather than requiring threaded shells.
- GXP compatibility: Designed specifically for SRAM GXP cranksets.
- Low weight: The PressFit design helps reduce weight compared with some traditional external threaded systems.
- Easy installation: SRAM describes PressFit as an easier installation method because the cups are pressed into the frame.

Best Suited For
Ideal for MTB riders, XC cyclists, trail riders, and recreational mountain bikers using a SRAM GXP crankset with a PF92/BB92 frame shell.
Important: GXP and DUB are different spindle systems. This bottom bracket is for GXP cranksets, not SRAM DUB cranksets. Also confirm that the frame uses PF92/BB92 before ordering; SRAM specifies different fit dimensions for PF89.5 and PF92 systems.
