Description of Mavic Ksyrium UST WTS Wheelset with Yksion Pro UST Folding Tires - 2020 - black

A well-loved favorite for its overall ride quality.

The Ksyrium road wheelset has long been considered a smart way to upgrade your bike. Now that it is available with Mavic's UST Road Tubeless technology, it is even smarter. For a reasonable price, you get all performance and dependability that go with the Ksyrium name plus the added benefits of tubeless, including less rolling resistance, a smoother ride quality and a reduced risk of punctures. And there is no other road tubeless system that is easier to use.
Mavic's UST rims and tires make it easy to change tires, mount and inflate. The wide rims (19 mm internal) are optimized for 28 mm tires (and still compatible with 25 mm), perfect for tackling a variety of road terrain with efficiency and control. Mavic's patented ISM (Inter Spoke Milling) 4D technology reduces weight for fast climbing and instant acceleration. If you are looking for an upgrade that can immediately boost your road bike's performance, look no further.

Mavic Road UST Tubeless technology

By combining their knowledge of wheels and tires, Mavic was able to perfect the symbiotic relationship between the tire bead and the rim hook to offer a system that is not only fast on the road and easy to maintain, but also 100 % reliable so you can focus on one thing - your ride.

Fast in line and quick through the turns

All-new rubber compound achieves the best balance of grip and low rolling resistance.

Safe and easy to use

Patented UST technology ensures the perfect union between tire and wheel, ensuring easy installation and removal.

Smoother ride and more puncture resistant

Ride with lower pressure for increased comfort and reduced risk of pinch flats.

Technologies of the Mavic Ksyrium UST WTS wheels:

FTS-L (Force Transfer System Light)

The reinforcement of the key transmission components brings a lighter and stronger hub to allow the energy to flow freely to the entire wheel.

ISM 4D (Inter Spoke Milling 4 Dimensions)

An exclusive Mavic patented concept, ISM 4D not only significantly reduces weight and reduces inertia without compromising durability, but also improves aerodynamics due to its new rim shape. Further advantages: up to 50 grams lighter for faster climbing, the lowest inertia for instant acceleration and a smooth aerodynamic rim shape to reduce drag.


- Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy for lighter and spicier rims.

QRM (Qualité de Roulements Mavic)

Mavic only uses high quality sealed cartridge bearings. On QRM wheels, they feature double sealing (2RS or LLU) together with tight C3 internal clearance.

SUP (Soudé Usiné Process)

A welded and milled rim joint which is extremely strong, eliminates shuddering when braking and offers superior wheel balance.


Clean with a dry cloth or soap and water. Do not use pressurized water.

Customer Reviews
Translated via google translator
This is my first look after firs (80km) ride. I will update the review later.
I watched a lot video online about how hard it was to get dirty with sealant, how hard it was to inflate tires without a compressor. So I was very skeptical about making tubeless wheels. Forget it - the Mavic UST perfectly combines wheels and tires. The sealant fills up well too. Reduced tubeless tire pressure, a real plesure( for my 74kg inflate to 6bar).
The rims themselves spin very well, I can't say much about weight, because - I’m not a pro cyclist, wheels not super light and I didn’t expect it.
The kit includes a sealant and a pre-filled syringe.
Summary - a great set of wheels for a reasonable price.
