Cosmic Pro Carbon SL UST Disc is rated 3.0 out of 5 by 5.
Rated 1 out of 5 by from Great wheels, terrible tyres! I took delivery of these wheels with the supplied Yksion Pro UST tyres exactly a month ago and whilst on a ride in Mallorca three days ago, I had a puncture from a slash all the way through the almost brand new main tyre tread, which the sealant could not seal. I didn't expect this from such new tyres that had not even completed 500 miles, and had to use an inner tube to carry on my ride. I now have a rear tyre that has very little puncture protection and is no longer tubeless - this is disappointing and frustrating considering Mavic's usual high standards. The wheels themselves are excellent - they roll extremely well and have made a huge aero difference from my old Aksium set up.

Rated 5 out of 5 by from Incredible wheels In the interest of balance, following my bad review of the tyres (on the tyre page), I’ve come here to say that these wheels are simply stunning! The road feel and speed are the best I’ve ever ridden. Tubeless set up was easy too.

Rated 5 out of 5 by from Nice Wheels, Durable? I bought the previous incarnation of these wheels, before they became UST. After I borrowed a pair from a friend and had to have some. The wheels are Brilliant. In two years and 10,000+ they have stayed true, the bearings still roll perfectly and I have had no issues, other than, contrary to what Mavic say, the braking is still very poor in the wet. I look after my stuff, and on polishing the bike today, I noticed that where the spokes cross, and where damage has occurred to the painted spokes, they have gone RUSTY! I wasn't expecting this presuming the spokes to be stainless, but I have just checked the spec, and the spec says Steel. I think my wheels are just passed the 2 year warranty, but I will be contacting Mavic about this issue. For now though if you are precious about these fantastic wheels, you may want to regularly check the spokes and touch up any damage.

Rated 1 out of 5 by from Disappointed Used three times in good conditions but the tyres just don’t hold up. Less than 100 miles with sealant and I had a puncture. It wouldn’t seal either which caused me huge distress trying to get home. Problem is the tyres are so tight you can’t even take a tube to swap to in the event of a problem. Pretty gutted actually to say the money I’ve spent on this. Really put me off Mavic who I have supported for over 6 years with lots of wheel purchases.

Rated 3 out of 5 by from Better Off Handbuilt Not enough spokes imo, considering the price I was expecting stiffer wheels. Also, the spokes rub against each under load which is annoying. On the plus side they are quite light and look really nice.

UST Tubeless Ready

UST Tubeless Ready

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.

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.



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.
