UST Road Tubeless lets you ride with lower tire pressure for smoother ride and a reduced risk of punctures
Our patented UST system offers a perfect union between tire and wheel, so installation, removal and maintenance are easy

Superlight for fast climbing and instant acceleration

ISM 4D rim machining makes for the lightest road rims
Zicral spokes lower weight while maintaining stiffness
Smooth-riding Yksion Pro UST tires

Ride with the confidence of a stronger, more durable wheel system

Fore drilling creates a stronger spoke/rim interface

Rated 1 out of 5 by from Corrosion After Just 2K Miles Extremely disappointed. Had to replace bearings and have rear hub serviced after 2,062.63 miles and 3.5 months because water penetration caused corrosion. Now pawl is sticking. Mechanic suspects corroded bearings put unusual load on axle and/or chipped pawl. Need to rebuild hub at my own cost. Dealing with Mavic warranty service is a huge hassle. Ironically, the LBS where I purchased these gave them to me as a replacement for a defective Ksyrium Elite Pro SL wheelset (weld slag in front wheel) that took months for Mavic to address and still didn't repair correctly.

Rated 4 out of 5 by from a few issues I have a few issues with this wheelset/tire combo. The video I watched claimed mounting/dismounting the tubeless tire was easy. For me it was a struggle and I dread getting a flat on the road and having to install a tube. Also I have trouble getting the front tire to hold pressure. An almost new front tire unluckily sustained immediate damage so I installed a new one. If I inflate the new one to 75-80 lbs it drops to 65 lbs on a 2-3 hour ride. I re-inflate before every ride. Aside from this, I like the feel of the tires on the road. It does take some getting used to ... riding much lower tire pressure than I am used to ... .

Rated 5 out of 5 by from Amazing! I installed these wheels on my Moots on February 1. Since then, I have ridden the wheels and tires more than 3000 miles. Today, I had my first real puncture and the Mavic sealant worked perfectly. When I got home, I noticed that there were several pinhole sized punctions and one 4-5mm. The tire still kept air! Thank you for making such a great product.

Rated 5 out of 5 by from Ksyrium pro ust Bunch of rides on this. Have been running road tubeless when Shimano and Hutchinson were it. Have been waiting for Mavic to jump in. Always loved Ksyrium, love it more with UST. Have a compressor but used a hand pump just for fun. Yup, it works. Only road tl have been able to do that with. Light, stiff, compliant.

Rated 4 out of 5 by from Awesome rims one defective tire The rims are stunning. The UST system worked for front tire, but like the other reviewer my rear tire has a leak in sidewall. So I have a tube in now. Clearly a factory defect. Mavic should send a replacement tire but have not responded.

Rated 4 out of 5 by from Great wheels I went from Ksyrium SL 08's to these new wheels. The instant start hub gives you immediate power of the line. Much quicker than my SL's. Love the fact I can go tubeless or clincher. These wheels are a winner for me. I hope maintenance is easy for the new hubs!

Rated 3 out of 5 by from Slow leaks Big step up from my open pro Ultegra wheels. Fast and stiff. Ride smooth at 87psi. My problem is air. Cannot keep pressure in the rear wheel. Need to pump every day. Finally did the water dip test yesterday. Find I am leaking in the side wall about 1/8 inch from the rim.

Rated 1 out of 5 by from Badly made I bought these for use in the French alps, but ended up not using them. In essence the rear wheel valve hole had been drilled off centre. This caused the valve to not sit straight and air weeped out over night. I confirmed this by putting both wheels in a vat full of water and air could be seen escaping from around the valve hole on the rear wheel and no such effect on the front wheel. I was quite surprised that such an expensive wheel could have been shipped with a visible to the naked eye fault. I bought them from wiggle and they refunded the purchase. In terms of the valve length they are too small for most high pressure pumps. I bought a bontrager high volume/high pressure pump which worked very well with these small valves . It pushed the tyres against the rims using the high volume setting with the "pop" sound in one or two pushes. I think mavic need to use longer valves and it will make things easier for people with standard high presure pumps.

Stiffer and stronger
Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.

Instant Drive 360

Instant Drive 360

The new Instant Drive 360 freewheel system is super light and fast to engage with only 9°. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.



Inter Spoke Milling 4 Dimensions
An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance ; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag



Stronger and smoother joint
Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.



Light and strong
Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.



Optimum energy transfer
The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.

Traction, control and lightweight
The UST concept improves traction, control and comfort while reducing inertia and flats.
The 'tubeless ready' construction results in a lighter tyre for improved performance.



Light, stiff and strong
A specific aluminum alloy that provides spokes with higher stiffness-to-weight ratio while being stronger.
