The Ksyrium has been appreciated for many years for its balanced riding characteristics and is chosen as a smart upgrade option for many racing bikes.
And now it's even smarter with Mavic's UST Road Tubeless technology. At a fair price, you get the Ksyrium-style performance and reliability - plus all the tubeless benefits: lower rolling resistance, smoother rolling and less risk of punctures.
In addition, there is no more user-friendly tubeless system. Mavic's UST rims and tyres make installation and tyre changes easy. Rims with 19 mm tread width are optimised for 28 mm tyres (still compatible with 25 mm tyres) - perfect for any type of road, with high efficiency and control. Patented ISM 4D weight tuning saves weight for faster climbing and acceleration. If you're looking for an upgrade that instantly improves the performance of your road bike, you've come to the right place.
Rolls faster and smoother - with less risk of breakdowns
