Mavic Ksyrium Pro Carbon SL UST Front Wheel

Now Mavic has added their UST Road Tubeless technology to the Ksyrium Carbon SL UST, the race day favorite has even faster. Eliminating the tube also eliminates friction, so you roll faster with greater efficiency. And now you can run lower tire pressures in the Yksion Pro UST Tubeless tires for increased comfort and a reduced risk of flats. As a bonus, the UST system including sealant weighs less than a traditional tube and tire system. Added rim width of the Ksyrium Pro Carbon SL Front Wheel (19mm internal/25mm external) allows for increased air volume in the tires, which further improves ride quality, and the rounded, smooth rim profile makes it one of the most aerodynamic wheels in its category.

The impressive iTgMax rim molding process is the key to effectiveness, durability and heat management of the carbon brake track. The resin that binds the carbon is enhanced through a proprietary heat treatment protocol that makes it able to resist heat better than any other carbon clincher rim. And a laser preparation of the brake track produces reliable braking performance. The spokes are using Mavic's patented elliptical bladed shape for increased aerodynamics. Being double butted they are light and improves the ride quality. Using 20 in front and 24 rear creates high stiffness, low weight and long-term reliability.

The front wheel-tire system comes with a 700x25 Yksion Pro UST tire that provides a simple, hassle-free tubeless road setup with high rolling efficiency and maximum grip in all weather. When you need a great all-around, mountain capable rim brake wheel, the Mavic Ksyrium Pro Carbon SL UST makes you tough to beat.
