Based on the best-selling design of our Hyalite models, the Hyalite 25 steps things up with a wider internal width, perfect for wide-tires and exploring the wide-world. At 25mm internal, it picks up where all-road and gravel wheels leave off.

Built to meet your all-day, all-road, gravel grinding needs, all-year-long. 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,
