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.

• Rim weighs only 430g
• No rim tape is needed, saving 60g over a traditional wheelset
• Flat, lightweight spokes and ID360 freewheel technology
• Laterally stiff and vertically compliant for a more dynamic ride
• Fore technology keeps the rim upper bridge solid to make the 19mm wide rim stiffer
• New Infinity hub platform: stiff axle, durable bearings, and new hub design
• Improved UST Road delivers more speed, comfort, and control in an easy-to-use tubeless system
• No tubes means less friction, better efficiency, and grip, with a reduced risk of punctures
• New rim bed shape makes it easier to mount and change tires
• Fore drilling technology doesn't require the use of rim tape

Additional Information

• 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 platform: optimal spoke tension balance is a guarantee for perfect stiffness and great durability, with only one spoke 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.
