COSMIC SLR 40 LTD

This all-new carbon wheelset is a great choice for road riders aiming to aiming to be fast and efficient in all types of riding and racing situations. Not only does the 40mm airfoil rim slice through the wind with minimal drag, but it’s also the lightest in its category.
A new rim laminate saves 40g per rim. The spokes attach to the rim without any need to drill the upper rim bed, so no rim tape is required. That means more weight savings (30g) and less hassle when it comes to set up or repair tubeless tyres; The new shape of the rim bed also makes it easier than ever to mount and remove tires. UST Tubeless setup means no tube, so no friction, and more air volume means a smoother ride. The result is a faster ride with super low rolling resistance. At last, our patented elliptical spokes save another 5 watts.
Our new Infinity hub platform optimizes the spoke lacing for efficient power transfer through highly controlled spoke tension. The Instant Drive 360 freewheel with automatic bearing preload adjustment (QRM Auto) provides fast engagement, high stiffness and added durability. In addition to more speed, you also get better braking control with our proven iTgMax technology. A patented laser treatment of the brake track shortens stopping distance in both dry and wet conditions, and a special lay-up and heat treatment process makes it the strongest and most durable of all carbon rims for rim brakes.
It's available for Shimano driver body and can convert to Campagnolo and SRAM XD-Road with optional driver bodies.
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.

Represented as an illustrator in Europe and worldwide by the Creasenso/Paris agency, Jérôme oscillates between his commissioned work for major brands or companies and his personal work, which he produces most often on canvas or on limited edition art prints. Thanks to his large flat tones of colour and his minimalist silhouettes, Jérôme
Masi’s style is instantly recognisable. His seemingly simple illustrations deal with various subjects, always treated in an elegant and poetic way. He manages
to create, with just what is necessary and nothing more, images where each
element has its own importance.

Key technology

Efficiency RigidityFore Carbon tapeless tubeless technology
Stiffer and stronger. Instead of drilling the rim to attach the spokes and nipples, a threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge to enable the spoke nipples to be directly screwed in it. As a result, the upper rim bridge is left undrilled and doesn't require the use of a rim tape to be sealed.
Efficiency RigidityInstant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Efficiency RigidityIsopulse lacing design
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.
Efficiency RigidityUST tubeless technology
Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.
Safety ReliabilityiTgMAX carbon clincher technology for rim brake
Integral Glass Transition Temperature. iTgMAX consists in an inner rim bed finished with multiple layers of seamless carbon fiber to achieve a unique one-piece rim contour without cutting any fibers. The brake track is then finished with a laser machining to ensure the best braking efficiency.
Safety ReliabilityInfinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
Safety ReliabilityQRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
