Description of Mavic Ksyrium Pro UST WTS Wheelset with Yksion Pro UST Folding Tires
Other major updates include redesigned lighter hub shells, the implementation of the fast engagement Instant Drive 360 hub and an automatic adjustment of the bearing preload for long terms smoothness with no lay. Still laced with Mavic’s proprietary Zicral alloy spokes that are stiffer, stronger and lighter than traditional stainless steel spokes. The Isopulse lacing pattern (radial lacing on the drive side) allows a more balanced spoke tension for a stiffer, more stable wheel.
Fore drilling creates the strongest possible connection between rim and spokes, increasing stiffness by about 20 %, and makes tubeless super easy to use, without the need for a rim tape. Each part of the rim is precisely machined using just the right amount of material to provide stiffness and strength, while maintaining weight at only 400 grams. All in all, the total wheel weight is down to impressive 1420 grams.
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 Pro UST WTS wheels:
Fore – 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.
By drilling only one rim wall, we made the rim four times more resistant to fatigue stress. All your energy is transmitted through a 40 % increase in rigidity.
Isopulse – This spoke lacing design and mounting brings better wheel stability, a constant spoke tension and a crystal clear transmission of energy.
Instant Drive 360 – The 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.
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.
Maxtal – Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy for lighter and spicier rims.
Zicral – Light, stiff and strong. A specific aluminium alloy that provides spokes with higher stiffness-to-weight ratio while being stronger.
QRM Auto (Qualité de Roulements Mavic Auto) – Mavic’s latest innovation. Those cartridge bearings are double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
SUP (Soudé Usiné Process) – A welded and milled rim joint which is extremely strong, eliminates shuddering when braking and offers superior wheel balance.
UB Control (Usiné Brut Control) – The braking surfaces are milled to improve braking friction and eliminate shuddering.
Features of the Yksion Pro UST folding tires:
Low rolling resistance and extra speed
- No more friction between tire and tube.
- The exclusive 11 Storm compound reaches the best balance of grip and low rolling resistance.
- Lighter than clincher tire + 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 tire pressure with no risk of pinch flats.
- Just 30 grams of sealant prevents most puncture.
Clean with a dry cloth or soap and water. Do not use pressurized water.
