DICUT® Technology
The RRC DICUT® wheel line up is a perfect blend of aerodynamics, technology and design. Their aggressive optics push the rider on the climbs. DICUT® hubs with their fine tuned flange geometry and straight pull spokes provide the stiffness needed. High modulus braking surfaces bonded with a heat resistant resin easily handle all descents. Dedicated carbon layers improve heat dissipation from the braking surface into the whole rim. Finally, on the last miles to the finish line, the aerodynamically refined rim profile and eleven speed compatibility help to cut through the wind with just the right gear and minimal drag. New for 2015 is the disc wheel RRC 2.0 Disc DICUT® T and the R 20 DICUT®, a lightweight allround aluminium wheel.
