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

By removing the inner tube, we've also eliminated friction, which reduces rolling resistance and thus the energy required to reach higher speeds.

The 30 mm deep rim optimises aerodynamic performance and improves stability in crosswinds. The alloy rim benefits from our unmatched experience in creating lightweight yet durable rim extrusions. To achieve this, we carefully adjust the thickness of the rim wall to strike the right balance between stiffness, strength, and weight.

Straight spokes are attached to our high-end 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 easily converts from a Shimano/SRAM cassette to a Campagnolo or XD cassette and is compatible with Center Lock discs.
