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.
-
Versatile: Suitable for several SRAM GXP crankset applications.
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.
