        From Trailhead to Podium

        The lightest and fastest mountain bike wheels we make, the XC-27s are made for cross-country speed, pure and simple.

        Highlights

        • The internal width of a 27mm hookless carbon rim creates a stronger, more stable footprint, creating speed and confidence
        • Grand Forza double-butted spokes keep it light while staying strong and reliable
        • Built with our custom straight pull HollowGram hub shell and ultra-reliable DT Swiss 350 rear internals for performance and ease of service
        • At 1450g a pair the XC-S 27 is lightweight and durable
        • A limited lifetime warranty to give you peace of mind
        • Ai-Offset & Shimano MicroSpline freehub body compatible

        Strength in Speed
        It’s not enough to just be fast. When it comes to your wheels, speed comes not just from low weight, but strength. A wheelset you can count on means you can pick lines, carve corners, and hit obstacles that others might second-guess. The XC-27’s internal rim width of 27mm affords a stronger and more stable footprint than you would think is possible for wheels this light. The first one across the finish line knows how much that means.
        Get (un)Hooked

        HollowGram wheels engineered with hookless rims bring lots of advantages: they save weight, they create stronger rims, and they help create a better seal for running tubeless tires. But the biggest appeal of hookless rims is that they enable greater tire volume once inflated, so you can run lower pressures for greater comfort and control, gaining speed and traction.

        Better Off Off-Center

        The XC-27 rim design offsets the spokes by a few millimeters, perfectly balancing spoke tension to handle the asymmetric forces imposed under pedaling and braking. The result is better response, greater reliability, and more control.
