Low rolling resistance and extra speed

No more friction between tyre and tube
New exclusive 11 Storm compound reaches the best balance of grip and low rolling resistance
Lighter than clincher tyre + tube combo

Easy to use and repair

Perfect match guaranteed with Mavic UST Wheel-System
Tight control over beads diameter and stiffness
Kevlar beads stretches just enough for easier mounting

Improved comfort with high flat protection

Lower recommended tyre pressure with no risk of pinch flats
Just 30g of sealant prevents most puncture
Available in 25mm and 28mm

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 1.9 out of 5 by 70.
Rated 2 out of 5 by from Second bubbled tyre I have a love/hate relationship with these tyres..... Pros - Easy to fit and roll fast Cons - these tyres bubble for no apparent reason I purchased Ksyrium UST wheels in May 18 ...... the first tyre lasted 500 miles before it bubbles ........ this tyre has lasted 1300 miles and has bubbled (pic attached). I have only used Mavic sealant and I m always careful not to exceed the stated max psi....... so what s going on Mavic? You can do so much better than this ! The wheel set has been brilliant , my experience with the tyres is not so brilliant. BUT I am a huge Mavic fan and hope that these bubbles are just an issue with a batch.

Rated 2 out of 5 by from Disappointing Having bought a Cosmic wheel set with a view to just a wheel upgrade, but as the set was complete with Yksion Pro UST tyres already installed and on advice of the advantage of tubeless set up decided to give tubeless a chance. Rear tyre holds pressure well so far but unable to comment on how it holds up on the road as the front will not hold pressure. Have tried several times, removed inspected, cleaned and refitted with still no joy. Will be trying with different rim tape after Christmas but won’t be holding out much hope. As theses were supplied already fitted to the rims very disappointing in the quality from a company such as Mavic.

Rated 3 out of 5 by from Grippy but Puncture Prone These tyres were supplied with a new bike from Canyon. In my first week of riding with them, the tyres have picked up cuts and two punctures while riding pristine roads in Spain - god only knows what will happen to them on UK roads over the next few weeks. I suspect I will have to pull these tyres off judging by the other reviews. The tyres offer a lot of confidence while descending at speed, especially into hairpins, probably more so the conti 4000sii but I would usually go months puncture free on new conti tyres. Also, being a new bike, the tubeless wheels were fitted with some extremely heavy 125g tubes. No liquid to make them tubeless???

Rated 1 out of 5 by from Death by a thousand cuts (Amazing grip) When I first used these tyres, I was amazed at how they felt, super smooth and amazing grip what more could you want. Unfortunately, after a few rides I started to notice more than a few nicks and some nasty holes. I’ve had the tyre off multiple times and patched them inside with high pressure patches as there is no way I should be ready to replace these, I’m only 1000km in on them. I was hoping they would last into the summer as it's clear they will be amazing in the dry conditions (I think) but at this rate they will be in the bin. At this moment in time I wouldn’t recommend them.

Rated 2 out of 5 by from Great new wheels - tyres too flimsy I have 4 pairs of Mavic wheels, including 3 sets of Ksyriums of varying vintages. I bought the latest to try out tubeless tyres and this hasn't gone well. I did a short ride after adding the sealant and used the wheels this weekend on an Armistice ride from Calais to Compiègne. A short while into day 2 the back tyre, inflated to 82-84 psi blew, there were no large objects of flint anywhere in the vicinity and the road was clean and smooth, I can only conclude that the split in the tyre was larger than the object that caused it as the tyre blew. Not impressed, I have a lot of Mavic products and I can't see how these are durable enough. Even the older Yksion tyres were more durable than this.

Rated 1 out of 5 by from Superb grip, horrendous wear and tear I have had these tyres on my Comete SL UST wheels for the last 6 months or so and done about 700 miles on them. As a tyre they are great, the grip is superb however the wear and tear of the tyre is horrendous, my ones need replacing now and to be honest have needed to be replaced for some time however the cost of them has meant I have been riding on tyres which are beyond repair. The wear and tear is so bad I would not purchase these tyres again which is a real shame as they provide great grip. Pictures shown below.

Rated 1 out of 5 by from Easy to use but terrible puncture resistance. I wanted to love these tyres because of how easy they are to use. They are extremely easy to put on and remove. They can be seated and pumped up with a hand pump. Putting sealant in the tyres is extremely easy with no mess. They are the best tubeless tyres to work with. Unfortunately, these benefits are for nought as their puncture resistance is incredibly poor. Th attached photos were taken after one ride on normal roads, during which time the tyres were cut up several times. In some cases, the sealant did its job and sealed the puncture, but one puncture refused to seal and I had to put in an inner tube (which rather defeats the purpose of a tubeless tyre). This is such a shame as these tyres would be perfect if they were not so fragile.

Rated 1 out of 5 by from Ruined after one ride Bought a bike from Ribble in January and upgraded the wheelset to Kysrium Elites, up until 2 days ago had used Schwalbe G-Ones on them. This weekend fitted the Yksion Pro Elites that also came with the wheelset for a sportive. The tyres rode well offering good grip, but after only 85km of riding the rear tyre had a huge cut approx 12mm long to the extent the inner tube was starting to bulge out the hole. I then carefully limped 5km to the station to go home. The wheelset is fantastic, and the grip the tyres offered was very good, but the durability of these tyres is pathetic and these will have to go in the bin
