The Cosmic Pro Carbon SL T was originally designed to meet the demands of pro teams who wanted a tubular carbon rim for the toughest conditions including the infamous cobblestones of Paris-Roubaix. Mavic went through intensive testing, putting an incredible number of prototypes through their paces until we achieved the standards our athletes demanded. Since then the Cosmic Pro Carbon SL T has won Paris-Roubaix and countless other demanding pro and amateur races. The carbon rims feature a unique depth-to-width ratio. At 40mm tall and 25mm wide, they deliver the perfect blend of aerodynamics, light weight, excellent tire support and strength. The 3K carbon external layer hides an incredibly complex inside lay-up using multiple types of carbon fiber that are hand-placed for complete precision. These unique rims attach to hubs that feature smooth, adjustable cartridge bearings (QRM+) and our lightweight, fast-engaging Instant Drive 360 freewheel system. The system comes with Yksion Pro tires, specifically designed for front and rear performance. The front Griplink tire offers a confident feel while cornering thanks to its supple 210 TPI casing, plus a water evacuation tread pattern and a nylon anti-puncture belt. The rear Powerlink tire has a supple 210 TPI casing and a tread pattern that optimizes efficiency and acceleration.
Grip and control
A front tyre, whether a clincher or a tubular, must fully liberate the wheel’s ability to hold the ground and control the bike. Therefore, GripLink tyres are optimized for front use, by offering a superior grip and extra puncture protection.
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.
Low rolling resistance
A rear tyre, whether a clincher or a tubular, must fully liberate the wheel’s ability to transfer power and generate speed. Therefore, PowerLink tyres are optimized for rear wheel use, by minimizing the rolling resistance.
Qualite de Roulements Mavic +
Our most demanding level. Those cartridge bearings are of course double sealed with C3 internal clearance, and toped with a micro-adjustability system.
Instant Drive 360
The new 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.
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 nrake track is then finished with a laser machining to ensure the best braking efficiency.
