40mm NACA inspired rim shape minimizes drag for added speed. Reduced inertia of the lightweight rim delivers instant acceleration. Flat double butted spokes saves weight and improves responsiveness.
Minimal drag, low inertia and high lateral stiffness makes it fast and efficient on all types of terrain, from the flats to mountain climbs iTgMAX brake track offers the best braking efficiency and highest reliability of all carbon rims.
Improved UST Road delivers more speed, comfort and control in an easy to use tubeless system
No tubes means less friction, better efficiency and grip, a reduced risk of punctures New rim bed shape makes it easier to mount and change tires.
