A well-loved favorite for its overall ride quality, the Ksyrium road wheel has long been considered a smart way to upgrade your bike. Now that it's available in a disc-brake version with our UST Road Tubeless technology, it's even smarter. For a reasonable price, you get all performance and dependability that go with the Ksyrium name plus the added benefits of tubeless, including less rolling resistance, a smoother ride quality and a reduced risk of punctures. And there's no other road tubeless system that's easier to use. Our UST rims and tires make it easy to change tires, mount and inflate. The wide rims (19mm internal) are optimized for 28mm tires (and still compatible with 25mm), perfect for tackling a variety of road terrain with efficiency and control. Our patented ISM (Inter Spoke Milling) 4D technology reduces weight for fast climbing and instant acceleration. The system is engineered specifically for disc brakes, with plenty of lateral stiffness for precise handling. If you're looking for an upgrade that can immediately boost your road bike's performance, look no further.

Ksyrium UST Disc is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Best value product in the Mavic lineup The Ksyrium UST disc wheels are absolutely the best value product in the Mavic lineup. The are fast, durable, comfortable wheels when running the tires tubeless. The grip of the Yksion Pro tubeless tires is excellent. The smoothness over rough and uneven pavement is fantastic. Once setup the reliability of the WTS is confidence inspiring. I recommend this WTS without reservation. Very well done Mavic.
