Crisp, reliable front shifting for your 2x10 cross-country or trail bike. The SRAM XX front derailleur was designed from scratch for 10-speed mountain drivetrains, so every push of the lever drops or lifts the chain fast and stays quiet in between. This is the bottom-pull, low-clamp version to fit a 31.8mm or 34.9mm seat tube.

Highlights

• Fast, definite shifts — SRAM X-Glide cage profiling moves the chain quickly between rings with less lever effort.
• Light and low-profile — a forged alloy clamp and formed steel cage keep weight down without giving up stiffness.
• Bottom-pull routing — suits frames that route the front shift cable along the down tube to the bottom bracket.
• Fits 31.8mm and 34.9mm seat tubes — supplied to clamp these two common diameters.
• Quiet running — optimised 2x10 chainline keeps the drivetrain efficient and rattle-free.

Built for 2x10

SRAM's X-Glide front shifting shapes the cage so the chain is picked up and guided onto the next ring quickly and predictably. The result is confident shifts under load on the climbs, where you need them most.

Compatibility and fit

For SRAM/Shimano 10-speed (2x10) drivetrains. This is the low-clamp, bottom-pull derailleur for 31.8mm and 34.9mm seat tubes (a separate shim is needed for 28.6mm). Designed for frames with a 66–69° chainstay/seat-tube angle. Match the clamp height (low or high) to your chainring size and frame. Best paired with a SRAM 10-speed front shifter.
