Tune Yokto 45/50 Disc Road Wheelset

The Yokto 4550 is Tune’s most radical expression of a lightweight aero road wheelset. It’s built around a singular idea: reduce everything that doesn’t directly contribute to speed. The rim profile is deliberately split—45 mm front, 50 mm rear. Stability where it matters, aerodynamic gain where it counts. Paired with a 25 mm internal width, the platform is optimized for modern road tires without overreaching into all-road territory. At the center is the Yokto hub system. Ultra-light, high-tolerance, and built around a minimalist 40-point engagement freehub. It’s not overbuilt. It’s precise. That distinction matters. What sets the Yokto apart is the spoke system. Carbon-wrapped CX-Super spokes reduce weight and increase stiffness, but come with constraints. This is a system that prioritizes performance over universality. It rewards a considered build. Hooked rims keep things grounded—secure tire interface, full compatibility, no pressure limitations. At 1290 g for the set, this is not just light for an aero wheelset. It’s structurally intentional. Everything here has been pared back to serve speed.
