XX was a global effort. Working across ten locations in six countries with an amazing team of engineers and designers, we collaborated to build the new standard of lightweight MTB performance. Driven and tested by our global teams of athletes, XX became a reality.
XX was an idea whose time was right: our first MTB group. We didn’t just want to be better—we wanted to be beyond comparison. Revolutionary front shifting, unmatched ergonomics, and unequalled hydraulic remote suspension lock-out, all in the first-ever 2x10 MTB package. But don’t take our word for it. Hear what our elite test athletes and tech support has to say.
The revolutionary machined design of the XX Cassette uses the same grueling manufacturing techniques that produced the PowerDome road cassette. With X-Dome, eight of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette. It’s a process that takes nine hours per cassette! The aluminum large cog can be replaced as needed. You have never seen a cassette that looks like this. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.
X-Glide is the common denominator that gives XX its unmatched shifting performance. With X-Glide, all four upshift locations are identical and can be picked up by any outer link. The result? Up and down shift locations have perfect timing, for an almost instant shift—even under load!
