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 quality 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.

UST system (including sealant) is 40g lighter than a traditional tire and tube system.
Aero-shaped rim features NACA profile for lower drag and improved crosswind stability.
25mm external width for improved rim/tire integration and superior handling in all conditions.
Patented elliptical spokes further enhance aerodynamics.

iTgMax technology carbon rim material can withstand temperatures up to 200° C.
Laser process removes resin from brake track while leaving carbon intact, producing predictable braking performance in dry or wet conditions.
