The Cosmic Ultimate was introduced 10 years ago and quickly became the wheel choice for pro racers seeking a competitive advantage. This version sees a major redesign with a new full carbon rear hub full carbon lacing and ID360 freewheel technology for improved responsiveness. With a NACA-inspired 40mm deep 25mm wide full-carbon tubular rim profile 20 super-bladed spokes and high thin carbon hub flanges it offers a clear and proven aero advantage. It’s also ultra-stiff thanks to the unidirectional carbon fiber spokes that don’t stretch. These spokes run continuously from one edge of the rim to the other through the hubs R2R technology creating one single spoke instead of two. This eliminates the need to mechanically attach the spokes to the hub. The rear rim is asymmetrical to improve the drive-side bracing angle so spoke tension is balanced and the wheel stays stiff under the heaviest lateral loads such as sprints or attacks. The rim is made of 12k carbon fibers wrapped over a super rigid foam core. Full-carbon construction means the whole wheel is incredibly light at just 1200g. Our unique iTgMax technology delivers reliable and consistent braking performance in both wet and dry conditions. It’s no surprise the Cosmic Ultimate is pro’s choice for the most challenging World Tour races. Cosmic Ultimate has been designed engineered and patented by Mavic in Annecy France and is 100% handmade in our European carbon factory.       SpecificationsCompatibility Rear axle: Quick Release only Front axle: Quick Release only Freewheel: Shimano/Sram convertible to Campagnolo and XD-R with optional driver bodies Compatible Adapters and freewheel bodies ID360 Shimano / Sram freewheel body V3430101 - Delivered on the wheel ID360 XD-R freewheel body V2580101 ID360 Campagnolo freewheel body V3440101 ID360 Shimano / Sram Light freewheel body V3850101 Weight Pair without tyre: 1200 grams Front without tyre: 540 grams Rear without tyre: 680 grams Hubs Front bearings : adjustable sealed cartridge bearings QRM+ Rear bearings : auto adjust sealed cartridge bearings QRM Auto Freewheel: Instant Drive 360 Front hub body: Carbon Axle material: aluminum Rear body: aluminum Intended Use Max.
