| Merchant: Performance Bicycle Mavic Cosmic Carbone 40 Tubular Wheelset - Closeout!. The Mavic Cosmic Carbone 40 wheelset is one of the most popular race wheels ever created. This full carbon tubular has been proven on the cobbles of Paris-Roubaix, where it won in 2011, and in the high Alpine passes of the Giro and Tour. It's stiff, lightweight, and strong and ready for racing. Despite the trend towards slightly wider rims, Mavic has continued to stick with a traditional V-shape, and for very good reason. In a straight line, the v-shape is still the most aerodynamic shape, and secondly, a v-shaped rim is purported to be substantially stiffer against torsional forces, so you get less rim flex while climbing or sprinting. The 3k weave carbon fiber rim also comes in a 40mm depth that provides a nice middle ground of lightweight and aero performance, protecting you from crosswind pressures while still dancing up climbs and slicing through the wind. The hubs are made from a carbon/alloy hybrid shell that sheds a few grams without compromising integrity. The freehub is the proven FTS-L system with the easy to service two pawl design Mavic is known for, and is compatible with 9/10/11-speed Shimano/SRAM cassettes. The optimized spoke dish and lacing improve wheel durability, aerodynamics and strength.
