This all-new high-performance wheel system incorporates our most cutting-edge technologies to give you a proven aero advantage on the road. We made it faster by minimizing friction, both through the air and on the ground. The NACA rim profile is 64mm deep and 26mm wide with an airfoil shape that is proven through countless hours of testing in our wind-tunnel to produce the lowest possible drag without sacrificing its stability. That’s how we addressed air friction. And to minimize friction between the tire and the road, we use our Road Tubeless system with the new Yksion Pro UST tubeless tire. Eliminating the tube greatly reduces friction inside the tire, giving you 15% better rolling efficiency. So you roll that much faster using the same amount of energy. The rims are engineered with our iTgMax carbon rim technology, and this version is purpose-built for disc brakes. It’s engineered with 24 spokes front and rear for perfect brake torque distribution. The front hub is convertible between a 12mm or 15mm thru-axle, or a quick-release. The rear is 12x142 thru-axle or quick release.
