The Mavic Cosmic Carbone 40 Elite Clincher Wheelset strikes a balance between the aerodynamics of carbon rims and the cost efficiency and durability of an alloy clincher. While this wheelset isn't as light as some of Mavic's highest tier offerings, it makes up for any gram differences with a much more wallet friendly price tag and durability that won't make you hang it up on training days. Mavic fashions the rim using its TgMax rim tempering and construction process. This means that an alloy spine is the anchor for an aerodynamic cross section built using different resins and 3k carbon fiber fabric. To minimize the braking issues that are all too common in carbon wheels, the rims are then cured to realign the carbon crystals. This curing and the better heat dissipation of the alloy core give the rims a higher glass transition temperature Tg, which is the point where the stiff, efficient carbon violently deforms. Higher Tg means less chance of wheel failure during heavy braking on long, steep descents. Aluminum inserts under the lower rim bed anchor the spokes, leaving the upper rim bed intact to increase stiffness and reliability. The end product is an aero rim with the stiffness of carbon and the durability of alloy. The hubs feature the FTS L system, which utilizes steel inserts to reinforce the area where force is transferred through the hub and allows for more energy efficient power transfer. The rims are finished with Mavic's Pro GripLink and PowerLink tires, both utilizing a hard center strip with grippy sides for confident cornering and low rolling resistance on the straights. Each wheelset also comes complete with quick release skewers, carbon specific brake pads, and a multifunction adjustment wrench.
