A SRAM bottom bracket is what it is so there's nothing to say about the product. Sigma's ordering was easy, it was a good price, and they delivered quickly and when they said they would.
Product Details
Performance & Use Case
The SRAM PressFit MTB Bottom Bracket is the OEM choice for fitting a SRAM crankset to an MTB BB89.5/92mm shell. Whether you're running the older GXP standard or the newer DUB system, the matching SRAM PressFit bottom bracket delivers a guaranteed-fit interface with full sealing and easy installation - press the bearing cups directly into the frame rather than threading them.
Construction & Materials
SRAM's seal architecture is engineered for MTB conditions where water and grit are constants. Two fully sealed cartridge bearings maintain low rotational friction across the bottom bracket's service life. DUB variants are significantly lighter than the GXP system that came before, saving around 40g over equivalent GXP fitments.
Compatibility
Fits any frame with an 89.5mm or 92mm PressFit MTB bottom bracket shell. Two spindle-compatibility options cover SRAM DUB (28.99mm oversized spindle) and SRAM GXP (24mm spindle - including XX, X0, X9 cranks). Select the variant that matches your crankset. ISO 4210 compliant.

About SRAM
Reinventing the ride, one component at a time.
Founded in Chicago in 1987 with a single product — Grip Shift — SRAM has spent four decades reinventing how riders interact with their bikes. From the first wireless electronic groupset to today's AXS ecosystem, the brand keeps asking the same question: how do we make the next ride better?
Wireless. Configurable. Ride-aware. SRAM's AXS platform replaces a tangle of cables and proprietary protocols with a single, app-driven ecosystem that spans road, gravel and mountain. Components talk to each other and to you.
