The low-profile GX 10-speed front derailleur was designed specifically for SRAM X-GLIDE shifting. Flawless shifting means you’ll never again compromise your speed & power in unpredictable off-road terrain. No more missed shifts, ever. X-GLIDE puts you in the right gear, right now. Technology: EXACT ACTUATION when we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing & exact cable tension. The result: the easiest index shifting system to set up & it stays that way.X-Glide Imagine being able to shift smoothly at any time, no matter what. We’re talking full-power shifts. Up, down, whatever the trail demands. The benefit of the X-Glide drivetrain is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you’ll never again compromise your speed & power in unpredictable off-road terrain. Here’s how we did it: TRUVATIV’s crank engineers threw away the old standards & developed a new chainring geometry from the ground up. They precisely paired the different-sized chainrings & redesigned where & 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.
