      Overview

      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
      • Built with DT Swiss Aerolite spokes for reduced weight and increased strength
      • Built with our custom straight pull HollowGram hub shell and premium, ultra-reliable DT Swiss 240 EXP rear internals for performance and ease of service
      • At 1350g a pair the XC-SL 27 is impressively lightweight and durable
      • Shimano MicroSpline freehub body compatible

      From Trailhead to Podium

      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.

      HollowGram SL: No Compromises

      HollowGram SL wheels rise to even higher speeds. Top-shelf DT Swiss Aerolite spokes are paired with custom HollowGram hub shells. Ultra-reliable DT Swiss 240 EXP internals at the rear bring a 36-tooth freehub ratchet for instantaneous pedaling engagement while minimizing mechanical drag. In HollowGram speak, SL means weight is lowered, responsiveness is increased, and efficiency is maximized.

      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.
