TRUVATIV XX 10-Speed Crankset

Coming in at 694g (BB30), the XX Crank delivers amazing performance and durability with no penalties in weight. The first MTB crank specifically designed for 2X10 uses some of the world’s most advanced material science. The oversized chainrings are CNC machined from 6mm 7075 aluminum blanks—2mm thicker than the competition. Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD) and a two-piece insert-molded carbon composite construction. The XX Crank geometry provides a narrow 156mm Q-factor, efficient chainline and beveled crank arms to maximize clearance. It’s pure science in action.

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