Lightning-fast, rub-free front shifting purpose-built for SRAM's XX 2x10 mountain drivetrain. This is the Direct Mount Spec 1 (S1) version with 42-28T tuning and dedicated top-pull cable routing, bolting straight to compatible frames for a clean, low-profile setup.

Highlights

  • Designed from scratch for 2x10 XX shifting - quick, smooth and precise
  • Direct Mount S1 interface (42.7mm bolt spacing) for a stiff, secure fit
  • Tuned for a 42-28T chainring combination
  • Dedicated top-pull cable routing
  • Forged alloy clamp body with formed steel cage and Torx T25 hardware

Built for the front shift

The XX front derailleur was engineered specifically for 2x10, giving you full big-ring range with no chain rub and a fast, confident shift under power. The forged AL-6061-T6 body and formed steel cage keep it light (around 120g) and stiff.

Direct mount, no clamp

Rather than wrapping a seat tube, the S1 version bolts directly to a frame's direct-mount tab, removing the clamp for a cleaner, more rigid interface. It suits a 66-69 degree chainstay angle.

Compatibility & fit

Use this on frames with a Spec 1 (S1 / 42.7mm) High Direct Mount front derailleur tab and top-pull (cable routed from above) cable routing. It is matched to a 42-28T chainring set on a SRAM XX 2x10 drivetrain. Confirm your frame's direct-mount standard and pull direction before ordering - S1, S2 and S3 mounts are not interchangeable.
