The Ksyrium 30 Disc is a perfect entry point into high-level race performance. This all-new 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 30mm deep rim 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.

The bladed straight pull spokes are laced to our high-end Infinity hub platforms : optimal spoke tension balance is a guarantee for perfect stiffness and great durability, with only 1 spokes length for both wheels to worry about.
The Instant Drive 360 ratchet freewheel system is quick to engage and offers low friction.
This hub easily converts from Shimano/SRAM to Campagnolo or XD cassette and is compatible with Center Lock disc rotors.
