A favorite for everyday road training and racing, this versatile wheel system produces a lightweight, dynamic ride quality that now has the added benefits of our UST Road Tubeless technology. This patented system provides seamless integration between the wheel and our new Yksion Pro UST tubeless tires that makes installation, removal, and maintenance easier than ever. You get all the benefits of tubeless, including less rolling resistance and a smoother, more controlled ride quality. Without tubes, you can run lower tire pressure with no risk of pinch flats, and the sealant helps prevent punctures.
The rims are engineered using our ISM 4D technology and a wider design (19mm internal/23mm external). ISM stands for Inter Spoke Milling, a unique process that trims the thickness of the rim wall between the spokes to create a rim that's lighter but still very durable. The rear wheel uses 24 straight-pull spokes laced to our lightweight, fast engagement Instant Drive 360 hub mechanism. Delivered in 12x142, it can be also converted to regular quick release.
Roll faster and smoother with a reduced risk of punctures
- With UST Road Tubeless, no tube means no friction, so you experience less rolling resistance and higher speeds.
- UST Road Tubeless lets you ride with lower tire pressure for a smoother ride and a reduced risk of punctures.
- Our patented UST system offers a perfect union between tire and wheel, so installation, removal, and maintenance are easy.
Climb, accelerate, and sprint faster
- 17mm internal rim width increases air volume.
- ISM 4D superlight rim
- Double-butted steel spokes keep the weight down for a fast and comfortable ride.
Powerful, reliable disc brakes for more confidence and control
- 24 spokes front and rear for optimized brake torque distribution
- Rear hub convertible from 12x142 thru-axle to quick release
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.
