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.
