KSYRIUM 30 DISC
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.

Key technology

LightnessMaxtal aluminum alloy
Light and strong. Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.
Efficiency RigidityInstant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Efficiency RigidityUST tubeless technology
Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.
Safety ReliabilitySUP welding technology
Soudé Usiné Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
Safety ReliabilityInfinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
Safety ReliabilityQRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
