Road disc brake technology has proven itself to many road riders and racers, even if the top pro's aren't fully on-board yet. The triathlon world has strongly embraced disc brakes as well. Affordable, with strong aero performance and reasonable weight, the Mavic Cosmic Pro Carbon UST Disc Front Wheel brings aerodynamics, disc braking, and UST tubeless technology to a huge segment of the cycling market. Engineered with Mavic UST technology, the 790g Cosmic Pro Carbon UST Disc Rear Wheel offers all the benefits of tubeless, including less rolling resistance, a smoother ride quality and a reduced risk of flats. The carbon clincher/UST tubeless disc-specific rims are made using an innovative Mavic rim construction process, which not only minimizes weight, but also improves strength and resiliency. The 45mm deep rims are NACA-compliant for low drag and excellent crosswind stability, while their lighter weight results in reduced inertia for explosive acceleration and climbing efficiency. The Cosmic Pro Carbon UST Disc Front Wheel is completed with a 25mm Yksion Pro UST tire for maximum rolling efficiency, grip and a smooth, comfortable ride making it a great option for high mileage riders, road racers, and short to middle distance triathletes who want great performance at a fair price.

The modern rim design has a 19mm internal width to complement it's 45mm profile. The key to the Cosmic Pro Carbon clincher/UST rim is the layered construction process. This full-carbon construction method is promoted by Mavic as offering best-in-class durability at lighter weight, with strength out to the tubeless bead. The inner rim bed is layered with seamless 3K carbon fiber, the contour is established without any cutting, resulting in a stronger, lighter rim with less resin, making it less susceptible to stress and heat. As the disc brake only rim doesn't feature a brake track the rim is lighter at the far exterior, yet incredibly strong to manage the rated max pressures of clincher or tubeless tires, which is why, for safety reasons, Mavic uses such an elaborate process, with exceptional results.

This front wheel features a 24 hole Center Lock disc hub, machined from aluminum, with an alloy axle, and Mavic' QRM Auto sealed cartridge bearings. The rim and hub are joined by straight pull, flat, double butted, bladed steel spokes laced 2x/2x using external steel ABS nipples. Service is simple and straightforward and the traditional style nipples make truing efficient and quick. The lateral stiffness of the wheel is impressive while the ride quality is better than expected due to the carbon rim defeating some vibration, assisted by the steel spokes. The hub comes equipped for a 12/100mm Thru-Axle dropout, but Mavic also includes the compatible endcaps for 9/100mm spacing as well for quick release use. ... Read More
