Ready To Rally The World

Whether blind racing or just blindly enjoying the trails as they come, the Roubion’s MX wheel combo feels like the best mix since Aperol met spritz. A 29-inch front wheel serves up high-speed stability and high rolling confidence. Meanwhile the 27.5-inch rear wheel makes for an intuitive and highly maneuverable rear end that loves to get sideways around the most ragged of switchbacks. We’re pretty sure there’s no better bike to tackle alpine terrain.

SRAM Eagle Transmission - stronger, better shifting, wirelessly

The next generation SRAM Eagle Transmission spec'd on our CC-carbon models is a radically robust, fully integrated and interdependent wireless transmission. Built around the universal constant of the wheel axle itself, the hangerless attachment mounts directly to the frame for a stronger connection and the derailleur provides unprecedented reliability in case of impact. Shifting under load is made possible due to a combination of X-SYNC technology and cassette mapping, creating seamless shifts even during your hardest power output. The new AXS Pods are ergonomic and customizable, so shifting gears is light and intuitive. It's simply the most advanced transmission and nearly as tough as you are.

Frame Sizing

If you're on the cusp between the recommended height range of two sizes, the absolute best thing is to try to ride them both. At a minimum, check the stack/reach measurements on your current bike and compare it to the new model you are looking at to get an idea of a fit you are already comfortable with. If riding the bike is not an option, consider the following.

The Roubion is available in sizes extra small - medium (XS-M). The small and medium are mixed wheel configurations. The extra small uses 27.5” wheels - both front and rear.
