SRAM GX 2×11 DM MTB Front DerailleurThis high-quality MTB model is a low-profile, highly-efficient front derailleur, which is designed specifically for SRAM 2×11 speed X-Glide shifting. When paired with a rear wide range SRAM cassette, this derailleur contributes to the widest range 2×11 speed drivetrain available and compliments shifting performance perfectly.Features: Material: Cage: Steel; Clamp: Forged AL6061 Compatibility: X-Actuation Speed: 2×11 speedMount: Direct Mount Weight: 153g (approx)Technologies: X-Actuation: Developed specifically for SRAM 1x, X-ACTUATION keeps shifting sharp and consistent across the entire cassette. X-Glide: No more missed shifts, ever. X-Glide puts you in the right gear, right now. SRAM’s engineers precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin-rather than the middle of the chain link-you get double the shift opportunities.
