X-DOME™ Technology Available in 9-speed - XG-999 The revolutionary machined design of the XG-999 cassette uses the same grueling manufacturing techniques that produced the XX as well as the PowerDome™ road cassette. With this XG-999 cassette, seven of the cogs are CNC machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

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.
No more missed shifts, ever. X-Glide puts you in THE RIGHT GEAR, right now.
