First Tubeless

These are my first tubeless tires. They are more expensive than regular tires, but match up to my mavic wheels perfectly. They have sealed on all but one puncture. I love having the peace of mind of knowing that these are the right tires for my wheels and that 95% of the time I will be rolling after a puncture without incident. They are also easy to remove and put back on.

im surprised people like these...

Sure they set up easy as TL but that is becoming less and less of a problem as TL becomes more prevalent. I rode these a few years back when Mavic first came out with them (and put them on all their road wheels). They are by far one of the slipperiest tires I've ever ridden. Even at 80psi they rode like wet leaves. Im sure they excel in some way but not in the way an $80 tire should excel in all ways.

Just right

I've ridden many road tires over the years, from 23mm, 25mm, 26mm, and now these 28mm tires. Race tires, comfort tires, and gatorskin tires. I've also used Hutchison's and Bontrager's first entry into tubeless, both were epic failures with a 100% failure rate (as diagnosed by the LBS) with about 16 tires each, between a friend and I. I've been running the now 2-3 year old Bontrager 26mm R3, which are good tires.

The Bontrager R3 tubeless is a great tire, but seems to wear quickly. The rubber on the Yksion is a bit harder, and seems to not wear as quickly over the first 200 miles as the R3. The Yksion tire is not as hard as the Hutchison, but its difficult to tell how much, given I ride the 28mm at 12PSI lower than the 25mm Hutchison.

Im running these tires on the 2018 UST Ksyrium Elite wheels. Descents down steep mountain passes and cornering are noticeably superior to my Bontrager Race wheels and R3 tires.

The tires do require sealant. While the bike was being built, the tires nearly went flat in 1-2 days. After applying sealant, riding and a second pump the third day, theyve lasted a few weeks.

I have yet to experience a puncture with the Yksion. The Mavic sealant is rated well, and has been easier to clean up than the Bontrager sealant. Also appreciate that Mavic does not nickel and dime you with valves, rim tape, sealant, spoke wrenches, valves, valve wrench, and tire levers. All included with the wheels!

Best of all, these tires do not require dish soap, two sets of tire levers, tire jack, and compressor to install. One tire lever did it for me, although you must follow the instructions.

FYI Mavic matched tire and rim production tolerances, so these tubeless tires may only be compatible with the right-sized Mavic UST rims, according to Mavic support.
