The Fulcrum Speed 25 combine lightness, agility, and control in a low-profile carbon wheelset designed to conquer steep climbs and guarantee stability on descents. Inspired by the iconic Racing Light XLR, these wheels bring pro-level performance to every rider, whether chasing KOMs in the mountains or riding ultra-distance events in challenging weather conditions.

With a 26 mm profile—symmetrical at the front and asymmetrical at the rear—the Speed 25 optimizes the balance between aerodynamics and stability. At just 1,285 g per set, they are among the lightest disc-brake tubeless wheels available, delivering the reactivity needed for uphill sprints while remaining stable in strong crosswinds.
