Dance up the climbs, crush the flats, swoop down the descents—do it all with speed and confidence on Mavic's R-SYS SLR wheels. These amazing hoops combine Mavic's tried-and-true technologies, such as their uber-light Maxtal rims with Exalith brake track and stiff, reliable QRM SL hubs with their revolutionary tubular carbon spokes. It all drastically reduces wheel weight while also significantly increasing stiffness for an incredible ride. The included Yksion Pro tires use a fast-rolling, long-wearing center tread with softer rubber on the sides for reduced rolling resistance and excellent cornering grip. These slick wheels and tires team up to bring you to the head of the pack and keep you there.
