The 2018 Mavic Ksyrium Pro Disc UST Wheelset updates the famous Ksyrium Pro lineage with UST Tubeless technology, improving the ride quality and comfort for long days in the saddle. Built to match the demands of discerning cyclists, this wheelset features 19mm internal-width rims that are UST tubeless-ready, designed to provide the lowest rolling efficiency and easy mounting of wider tubeless-ready tires. Strong yet lightweight, the rims are milled using Mavic's ISM 4D technology to shave weight where it's not needed, and further improved by Mavic's Fore Drilling to create a better connection between the bladed straight pull spokes and the rim. The Ksyrium Pro Disc UST wheelset is available with either 6 Bolt or Centerlock compatible hubs.

The bladed Zicral spokes lace down to Mavic's lightweight and versatile aluminum hubs, the rear using Mavic's Isopulse asymmetric lacing for a better balance between the left and right sides of the rear wheel. Shipped with 12mm thru-axles, the hubs are convertible to either QR or 15mm (front) with optional adapters (not included). The Ksyrium Pro Disc UST Wheelset comes mounted with 25mm front and rear specific Yksion Pro UST Tubeless Ready tires.


  • Weights: 1090g front / 1230g rear / 2320g set (Centerlock).
  • SUP arc-welded rim joint.
  • 24 bladed Zicral spokes front and rear.
  • UST Tubeless ready 19mm wide rims.
  • Hubs convertible from thru-axle to quick release with optional adapters (not included).
  • Includes: Mavic Tire sealant, multifunction adjustment wrench, UST valve and accessories.

Fantastic wheelset

OK, I guess I am a Mavic Ksyrium fanboy of sorts having used them since 2003 when I got my first set.... which I still have and which is still usable after 50,000 miles. This new set I just got for my Lysnkey GR300 gravel bike to improve road capability since I find myself riding that bike a lot on the roads lately. I already had a set of Mavic Ksyrium AllRoad Pros with their 40mm tires. That is another fantastic set of wheels.

Everything about these is great. I love the blind spokes and sealed air chambers so no stinikn' rim tape necessary. The flat Zircal spokes and the rims are very strong making for a bullet proof wheel.

The only issue I had was that I wanted a higher volume tire so I mounted 28mm Continental GP5000 tubeless tires. Getting them on was a bear. Whether the wheels are a tad big or the tires are a tad small, who knows. I wish the industry would settle on and follow more precisely more exact UST standards. I did need to use my air compressor to seat the beads. But the ride is fantastic. Roadside flat repair with a tube might be difficult but should be doable. But I don't expect to get many flats.. pinch flats will be highly unlikely and the sealant should fix small punctures.

The Mavic 25mm tires look pretty good and I'd try 28s if they make would them. Maybe those would be easier to mount than the Contis.

Tubeless Convert

Simply a high quality, high performance, product. The tires fit perfectly. The wheelset includes everything for tubeless setup. The tires come seated. The valve stems are installed. Just add sealant and inflate.

Use ALL of the provided sealant! I really like how the tires feel on the road. The tire volume is average to small for a 25c tubeless. Which is perfect. It is not a wobbly feeling balloon. Confidence in a 35mph hard decreasing radius corner. Feels awesome running down the access road at 49mph solo. Noticeably easier on the climbs than wider rims.

Rides naturally in a straight line without thinking, unlike some aero wheels with high volume tires.
