Key benefits
Accelerate and climb faster, hold higher speeds
40mm deep/26mm wide NACA profile optimized for rim brakes
Patented light aero spokes
Stiffer wheel for improved power transfer and superior braking
ID360 freewheel technology for instant power transfer
iTgMAX brake track offers the best braking efficiency and highest reliability of all carbon rims
Improved UST Road delivers more speed, comfort and control in an easy to use tubeless system
New rim bed shape makes it easier to mount and change tires
Fore Carbon drilling technology doesn't require the use of rim tape
A new rim laminate saves 40g per rim. The spokes attach to the rim without any need to drill the upper rim bed, so no rim tape is required. That means more weight savings (30g) and less hassle when it comes to set up or repair tubeless tyres; The new shape of the rim bed also makes it easier than ever to mount and remove tires. UST Tubeless setup means no tube, so no friction, and more air volume means a smoother ride. The result is a faster ride with super low rolling resistance. At last, our patented elliptical spokes save another 5 watts.
Our new Infinity hub platform optimizes the spoke lacing for efficient power transfer through highly controlled spoke tension. The Instant Drive 360 freewheel with automatic bearing preload adjustment (QRM Auto) provides fast engagement, high stiffness and added durability. In addition to more speed, you also get better braking control with our proven iTgMax technology. A patented laser treatment of the brake track shortens stopping distance in both dry and wet conditions, and a special lay-up and heat treatment process makes it the strongest and most durable of all carbon rims for rim brakes.
It's available for Shimano driver body and can convert to Campagnolo and SRAM XD-Road with optional driver bodies.
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.
