While we've all seen various studies and tests demonstrating that 80mm hoops can save watts on long, straight, calm courses, they may not be exactly what you're looking for when the wind starts to howl or in a downtown crit riddled with 90 degree corners. That's why Mavic designed the CXR Ultimate 60 Tubular Wheelset for aerodynamic benefits that aren't stymied by a little adversity. It sacrifices 20mm of depth compared to its 80mm sibling, but it still possesses all of the other wind cheating characteristics that define the CXR line, recommending it for criteriums, TT's, triathlons, road races, or as a versatile platform that can transition between virtually every road discipline. Mavic starts with full 3k carbon fiber to shape the CXR 60's rims, ensuring rigidity and reliable power transfer. This includes a full carbon braking surface, which is a rarity in Mavic's line and is designed to work specifically with the softer, CXR carbon specific brake pads included with the wheelset. Mavic considered both the wheel and rim profile when designing the CXR 60s rather than the rim alone, as its key focus with the CXR series was achieving truly integrated system rather than a rim and tire working independently of one another. Mavic's engineers paid close attention to the four points of contact the wheels have with the air in the front and at the rear portion of the rim, accounting for differences by shaping each independently to guarantee improved laminar airflow over the entire rim. Though the profiling is impressive, Mavic's use of its CX01 blades to seamlessly integrate the wheel and tire is what truly sets the wheelset apart from its less integrated peers. The system involves rings that snap in place in the small area between the wheel and tire to eliminate gaps and ridges in the transition from carbon to rubber. The uninterrupted plane smooths laminar airflow around this often troublesome gap, reducing drag and encouraging the air to flow uninterrupted over the e...
