This is the pinnacle of tubeless carbon wheels
Ultimate isn't just a name, it's the perfect description of this balance bike. And that is now compatible with tubeless and clincher tires, but in any case only for disc brake racing bikes.
At just approx. 1225 g, it achieves the ultimate balance between lightweight, top stiffness and aerodynamics.
The rim is based on a 100% carbon, 45 mm high and 27 mm wide NACA aero rim profile. Their complex fiber lay-up optimizes the stiffness / weight ratio. And the carbon top layer has the attractive UD² finish.
Because the rim base is not drilled through, no rim tape is required to make the rim airtight - this is the guarantee for trouble-free tubeless operation.
With 20 ultra-slim aero spokes each and extra high, narrow hub flanges made of carbon, it actually and demonstrably offers advantages in terms of aerodynamics.
It is also ultra-stiff thanks to spokes made from unidirectional carbon fibers that do not stretch. They run continuously from one side of the rim to the other - with R2R technology, two each are replaced by a single spoke, which also does not have to be firmly anchored to the hub. This also increases the rigidity of the impeller.
Industrial bearings with automatic bearing preload are used in the carbon hub bodies. The Instant Drive 360 freewheel on the rear wheel ensures lightning-fast frictional engagement (40 points of engagement = 9 °) and minimal friction losses. The hubs are thru-axle compatible (front 12x100 mm, rear 12x142 mm), only for center-lock brake discs.
This impeller was designed, developed and patented by Mavic in Annecy (France). It is 100% handmade in France.
Highlights
- The stiffest system wheel in its class: carbon spokes with high tensile strength. R2R lacing. UST tubeless rim without rim tape
- Thanks to ultra-lightweight & top aerodynamics, climb, sprint and accelerate faster: monobloc construction made of full carbon. 45 mm high NACA rim profile, which is seamlessly spoked into extra high, thin rim flanges with elliptical spokes

Technologies used
In this chapter we explain the technologies that the manufacturer uses for this product.
Instant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and ensures a fast frictional connection with only 9 ° pressure angle. A large, non-contact rubber seal reduces friction. And a wide selection of stub axles ensures compatibility with many installation standards.
R2R carbon spoke technology
Lighter, stiffer, more stable. Rim to Rim. The unique R2R spokes run from one side of the rim through the hub to the other.
QRM Auto Bearing Adjustment Technology
Qualite de Roulements Mavic Auto. Mavic's latest warehouse innovation. These industrial bearings (bearing clearance: C3) are of course double-sealed. Your bearing play is automatically adjusted to guarantee smooth running without any play.
