The Cosmic Elite is a perfect entry point into high-level race performance. This UST Road Tubeless system delivers a smoother ride and improved puncture resistance while retaining a lightweight feel for climbing and accelerating.
By removing the tube, we've also removed friction—so there's less rolling resistance, which means it requires less energy to reach higher speeds. The UST system, including the sealant that makes the tires more resistant to punctures, is also 40g lighter than a traditional tube and tire system. Wind tunnel testing led us to create a 30mm deep rim that optimizes aero performance and improves stability in crosswinds. The alloy rim benefits from our unrivaled experience creating light yet strong rim extrusions. We do this by carefully tuning the thickness of the rim wall to hit the sweet spot between stiffness, strength, and weight.
It's also engineered specifically for disc brakes with steel-bladed straight-pull spokes that are stronger than traditional J-bend spokes, all connected to our strongest hub platform, running on smooth, QRM bearings.
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 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.
Added speed and efficiency for sprints and solo riding

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.
