Mavic Cosmic CXR 80 Carbon Road Wheelset - Tubular $2,799.90
Superior aerodynamics with a complete wheel-tire system.
The Mavic Cosmic CXR 80 Carbon Tubular Wheelset is more than just another hoop in the Service Course. Garmin-Sharp won two team time trials with these wheels under them, which indicates to us that Mavic nailed the wheel-tire system in both concept and implementation.
The Cosmic CXR 80 Carbon Rims are constructed using carbon fiber with a 3K finish weave, and an 80mm depth. Aerodynamics are clearly at the forefront of the design, and Mavic's wind tunnel data reports as much as 1.25 seconds per kilometer in savings. Time and weight savings aside, the Cosmic CXR 80 is exceptionally stiff, transferring your power into forward motion with minimal loss.
Mavic uses its signature carbon-bodied hubs with aluminum flanges to house the QRM+ cartridge bearings. The double-sealed bearings have a tight tolerance for high rolling efficiency and are micro-adjustable to make sure you get every watt you make. For greater efficiency and durability in the rear hub, two stainless steel FTS-L inserts are used in the contact area between the pawl and hub body.
Sixteen bladed, straight-pull, steel spokes lace the rims to the hubs in a radial pattern on the front wheel. The two-cross/radial pattern on the rear wheel splits the difference between stiffness and weight, and utilizes twenty of the same spokes as the front. The Cosmic CXR 80 Carbon Wheels work as a system with Mavic's Yksion CXR Griplink/ Powerlink front and rear specific tubular tires. Having the right tire for the job increases your efficiency, but Mavic stepped it up a notch with CX01 blade. This small, lightweight blade snaps seamlessly into the small gap left between the rim and tire. The wheel-tire system improves laminar airflow at all yaw angles and minimizes turbulence where the rim and tire meet. The Griplink/Powerlink tires use two durometers of rubber, and a supple, high-density casing for exceptional cornering and control. A nylon, anti-puncture breaker belt increases the tire's resistance to flat-causing road debris.
The Mavic Cosmic CXR 80 Carbon Tubular Wheelset comes with BR601 quick releases, wheelbags, CXR-specific brake pads, valve extenders, a multifunction wrench, and a user guide. They come in Black with Black tires and are available with a Campagnolo or Shimano/SRAM compatible freehub body.
