The Yksion Pro UST offers the best blend of low rolling resistance, grip and comfort, a trilogy that is usually impossible to reconcile.
The rolling efficiency has been measured 15% lower than a tubetype equivalent in our lab and in real life.
Our testers have also found it super fast in wet turns, bringing them an unmatched confidence.
Being tubeless, it can be run at lower pressure (about 1 bar / 15PSI less) than a standard tubetype tyre, with no loss of efficiency and with less risk of pinch flat.
And what's usualy the achille heel of tubeless (mounting and servicing) has been solved by developing it together with our own wheels for tighter tolerances. The stretchable kevlar beads are super easy to mount and dismount. With just 30g of sealant, it's as airtight as a butyl tube and offers a nice puncture protection.
Available in 25mm or 28mm.

Yksion Pro UST is rated 1.5 out of 5 by 2.
Rated 1 out of 5 by from Just as expected Recently I bought my Canyon witch had a Ksyrium Pro Carbon UST Disk wheel set and Yksion Pro UST tires on it. I made it tubeless instantly. But after about 2.500 kilometers in two moths I had so many punctures that I started to question the concept of tubeless riding, with is quite stupid. But them I remembered some of my earlier setups (Schwalbe) witch never gave me any hassle. So I persevered in tubeless riding, but I lost confidence in the Yksion tubes. So after using a bottle of sealant I bought a few Continental's. Just forget it: impossible to mount. So, after 2.500 km, I had to buy a new set of tubes cause It felt like I was riding on sealant only. Strangely, all but one of the punctures were on the rear wheel. I would like to keep using Mavic tires, but just the thought of the wear and tear makes me sad. I shouldn't have to worry, but with an average of 3 punctures per 150 km isn't helping.

Rated 2 out of 5 by from The good and the bad Driven 2500k in dry conditions. The good (part one): the ride is perfect on these tyres. Great comfort, much better cornering. The bad (part one): I gor a puntcture after 2500k that did not heal as promised. Note: the air came trough an average size cut, of mabye 3mm across, of which you usualy have a few on a 2500k old tyre. The tyre deflated to about 2bar. Pumping only meant losing air again. After a few tries it inflated to 6 only to start losing air again after a few km. The good (part two): it stayed at about 3 or 4 bar now, and I found out I could perfectly well ride it home that way. However: it wil not let itself be pumped up tot normal presure anymore. Losing an euro 50,-- tyre after 2500k is too quick. Also dissapointing that the tyre did not heal itself as promised. It makes me doubt if I want to go trough riding these tyres. Closing note: the 'montage' works well enough, but the seringe could be better. The see-through tube barely fits on the seringe. All in all it is impossible tot get the latex fluid in without making a mess.
