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 and exact cable tension. The result: the easiest index shifting system to set up and 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 and power in unpredictable off-road terrain.

Here’s how we did it: TRUVATIV’s crank engineers threw away the old standards and developed a new chainring geometry from the ground up. They 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.
