The Ksyrium wheel from Mavic has a storied history. As the worthy successor to the Helium, arguably a wheelset that along with the Cosmic spawned the prebuilt wheel movement, it was catapulted to success by the pros in the grand tours and classics in the early aughts. Quite a bit has changed on the racing front since then, namely the move to carbon wheels. While the pros continue to race on tubulars, we don't always have the luxury of a team car following us, so we think the next best thing is tubeless. That's where the Ksyrium Pro UST Wheel shines, leveraging its tubeless know-how from way back in 1999 with its mountain bike going Crossmax wheelset, which coincidently coincided with the release of the original Ksyrium, the wheels combine the weight savings, flat reduction, and ride quality of tubeless. The effect of Mavic's generation of tubeless genius becomes apparent early in the process of mounting the tires. We all love the lower rolling resistance, cushier ride, and increased puncture resistance of tubeless tires, but mounting them is an admitted hassle that's left a lot of us sticking with traditional tubes. Mavic's road UST design virtually eliminates any of these misgivings. First, the tires mount without levers. Mavic recommends tire levers if you'd like, but, in our experience, the brand's UST tires pop on and off with bare hands as easily (or more easily than) most tires on most other competitor's rims. The ease of installation and removal alone make a compelling case that Mavic is once again the leader in road wheel reliability, but the ease of inflating the UST design removes all doubts. Tricks for seating tubeless tires are often just that: tricks that involve a bit of luck for all but the most capable wrenches. Mavic turns this on its head: mounting UST tubeless tires to UST tubeless rims is less an art and more of a simple, easily reproducible act of science. Just pump them up. That's it.
