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.
We 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.
But designing the best all round racing wheel is about more than just low weight. There are four other key elements:
High lateral stiffness
Thanks to the 24 rear spokes and the Isopulse lacing that makes for better spoke tension balance and higher stability, the Cosmic Pro Carbon SL T delivers plenty of lateral stiffness, while keeping vertical compliance at its best for great overall comfort on long rides and great tyre traction on rough roads.
Best-in-class braking efficiency
At some point on a mountain climb, you’ll need to fly back down to the valley. So we’ve focused on achieving short braking distances in dry or wet conditions. Our exclusive TgMax technology uses heat treatment and surface preparation to deliver this with wet stopping distance 50% shorter than the closest competitor.
You may be pushing your own limits, but you won’t get anywhere near the wheel’s limit. Cosmic Pro Carbon SL are sturdy, with strong axles and bearings and solid spokes and rims. Their low weight doesn’t limit their ability to meet our high standards of toughness and reliability.
Yksion Pro Tubular tyres
Mavic Cosmic Pro Carbon SL T comes with our high-end Yksion Pro Tubular. Made of a supple 220 TPI casing, these tyres have a tubeless construction that delivers a super low rolling efficiency and a great ride quality at an impressive weight of just 270g in a generous 25mm section.
The front tyre gets our Griplink tread pattern that’s designed to move water away when cornering for a safe grip in all conditions.
The rear tyre offers our Powerlink design that limits the pressure on the ground for minimum rolling resistance, while moving water quickly away for great traction in wet conditions.
