The Ksyrium 30 Disc is the perfect entry into high-performance racing. This brand new UST Road Tubeless system offers a smoother ride and better puncture resistance while maintaining a lightweight feel for climbs and accelerations.

By eliminating the inner tube, we have also removed friction, which reduces rolling resistance and thus the energy needed to achieve higher speeds. The 30 mm deep rim optimizes aerodynamic properties and improves stability in crosswinds. The aluminum rim benefits from our unmatched experience in manufacturing lightweight and stable rim extrusions. We carefully adjust the wall thickness of the rim to find the right balance between stiffness, strength, and weight.

The straight spokes are attached to our premium Infinity hubs: the optimal balance of spoke tension ensures perfect stiffness and great durability, with a single spoke length for both wheels. The Instant Drive 360 freehub system engages quickly and offers low friction. This hub can be easily converted from a Shimano/SRAM cassette to a Campagnolo or XD cassette and is compatible with Center Lock discs.
