All-roads. All Day. Gravel bound. Race Ready.

One great wheelset. Many applications. Move seamlessly between types of terrain, seasonal riding and from bike to bike, with the Hyalite.

Built to meet your all-day, all-road, gravel grinding needs, all-year-long. With a stiff build and bomber hubs, it’s a wheel you can trust for even the most remote days. Our asymmetric rim design improves the tension balance by up to 30%! The 22mm internal-width is optimized for 28c-45c tires, but could easily take up to 2 inches of rubber when the case calls. Define “gravel riding,” as you choose, this wheel has it handled.

Plus, when it’s time to gear-up for ‘cross season, it’s still got you covered. Tubeless ready rims and disc specific build have you ready for low pressure and ready mud.

Available in either 700c or 650b, they’re paired with USA made XST+ hubset, featuring a T2 high-engagement drive and bomber Titanium free-hub.
