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.
There's no other road tubeless system that's easier to use. Our UST rims and tires make it simple to change, mount, and inflate tires. 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) 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 and total axle and freewheel compatibility.
If you're looking for an upgrade that can immediately boost your road bike's performance, look no further.
Roll faster and smoother with a reduced risk of punctures
- No tube means no friction, so less rolling resistance and higher speeds.
- Ride with lower tire pressure for smoother ride and a reduced risk of punctures.
- UST system offers a perfect union between tire and wheel, so installation, removal, and maintenance are easy.
Lightweight rims for easier climbing and faster acceleration
- ISM machined, welded rims.
- 19mm internal rim width for low rolling resistance and extra comfort with 28mm tires.
Lateral stiffness boosts agility and efficiency
- Optimized bearing placement
- Straight-pull bladed double butted spokes deliver optimal stiffness.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
