So fast that the braking performance had to be improved: the Cosmic Pro Carbon SL UST wheelset by Mavic

Mavic's Cosmic Pro Carbon SL UST wheel represents the absolute top of the range in carbon clincher wheels, combining lightness with strong aerodynamics and UST Road Tubeless technology. This results in an incredibly powerful all-round wheel with extremely low rolling resistance, smoother and even more comfortable rolling characteristics and the safety plus due to the reduced risk of punctures. In addition, the tubeless system is easy to use when first mount, changing tyres and maintenance. The rims of the Cosmic Pro Carbon SL UST with 19 mm inner width fit perfectly with 25 mm wide tyres. The aerodynamic NACA tread pattern of the wheel reduces air resistance and at the same time increases riding stability in cross wind conditions. The rims are made of mats with continuous carbon fibres to achieve a unique rim profile " from one piece" directly in the mould. This technology is called iTgMAX, because the rims withstand temperatures up to 200° C with their superior heat management. This exclusive manufacturing process, followed by laser machining, results in extremely smooth braking surfaces and consequently shorter braking distances in both dry and wet conditions. On the rear wheel, Mavic uses the lighter, extremely fast engaging Instant Drive 360 freehub.

Integral Glass Transition Temperature. iTgMAX means an inner rim bed sealed with multiple layers of seamless carbon fibre to achieve a unique one-piece rim shape without cutting away fibres. The brake track is given a lasered finish to guarantee optimum braking efficiency. Consistent and efficient braking, 50 % less time to decelerate in wet conditions. The most reliable carbon rim that withstands the toughest use of the most powerful riders in the worst conditions.

QRM+ (Front)
Qualité de Roulements Mavic +. Mavic's most sophisticated bearing technology: with double seal and extremely dimensionally stable, micro-fine adjustable - according to your needs: super-smooth for maximum rotation and minimum tightening in bad weather conditions.

QRM Auto (Rear)
Qualité de Roulements Mavic Auto. The latest bearing innovation by Mavic. These cartridge bearings (bearing clearance: C3) are of course double sealed. Their bearing clearance is automatically adjusted to guarantee smooth running without any play at all times.

Instant Drive 360
The Instant Drive 360 freehub system is super-lightweight and provides a fast frictional connection with an engagement angle of only 9°. A large, non-contact rubber seal reduces friction. And a wide selection of axle caps ensure compatibility with many standards. Features: oversized axle and hardened aluminium freehub body save 40 g. 2 40-tooth pawls ensure a fast frictional connection (9°). Radial seal guarantees low friction at high speed and perfect water-tightness.

Isopulse (Rear)
This special lacing (radial on the right, double cross on the left) increases the stability of the wheels and ensures optimum power transmission - thanks to more even spoke tension on the left and right hub flange. Higher stiffness under heavy loads - for direct power transmission. Higher wheel stability - for lower maintenance requirements.

Road UST
UST means Universal Standard for Tubeless and is compatible with UST Tubeless Ready tyres. The UST technology improves traction, control and riding comfort with reduced inertia and reduced risk of punctures. Road UST is a complete system where wheel and tyre are developed together. This ensures a 100 % fit between rim and tyre. The rim production is so precise that the ETRTO standard is more than met. The tyre bead is made of Kevlar and not carbon, which increases the stiffness.

UST Tubeless Ready (Tyres)
The UST concept improves traction, control and comfort - while reducing sluggishness and the risk of punctures. The Tubeless Ready construction results in a lighter tyre for even better performance.

11 Storm
Exclusive rubber compound with perfect balance between rolling efficiency and grip.

The tyre carcass is reinforced with an extra layer to prevent punctures. Additional protective layer: reduced risk of puncture. More robust carcass: increased durability.

verified purchase

Laufen sehr gut und sind bei bc sehr günstig.
Ich meine die einfachste Art an einen LRS mit vormontierten tubeless Reifen zu kommen.
Ich würde sie jederzeit wiederkaufen, bestimmt die Disc Variante wenn ich mal auf Scheibenbremse umsteigen werde.
