Scope R4.a Cl Disc Tubeless 2026 Gravel Wheel Set. Dominate the road with the SCOPE R4.A CL Disc Tubeless 2026 wheelset. Derived from the Artech series, these wheels boast AEA 2.0 technology for optimized aerodynamic profiles and a clean look with internal spoke nipples. Experience effortless tubeless setup and lasting pressure with their perfect tire fit system. Engineered for strength and minimal weight via local carbon reinforcement, and featuring the lightweight, durable DIAMOND Ratchet hub system with a labyrinth seal for exceptional longevity. Race-ready performance redefined. Race A - Road wheels.Developed for trails.Derived from the revolutionary Artech series, the new R series uses the proven rim profiles of the Artech series, without Aeroscales.Using our AEA 2.0 technology, the optimal rim profile is defined, ensuring optimal aerodynamic performance.AEA.Algorithm Enhanced Aerodynamics.The rim profile of our wheels is developed using our AEA (Algorithm Enhanced Aerodynamics) technology.This algorithm calculates the most aerodynamic rim profile to ensure optimal performance.Internal spoke nipple.The internal nipples are hidden inside the rim for a cleaner look and a slight aerodynamic advantage.Perfect tire fit.The unique geometry of our Scope Tubeless system ensures easy mounting, direct inflation, lasting pressure, and compatibility with all (tubeless) tires.Lightweight design.Thanks to our local carbon reinforcement technology, we increase the number of carbon layers around the spoke holes inside the rim.This significantly reduces weight while maintaining strength and stiffness.DIAMOND Ratchet.Lightweight and durable.The hubs are equipped with our diamond-reinforced ratchet engagement system for direct engagement, improved durability, and significant weight reduction.Labyrinth system.Our hubs feature a mechanical labyrinth system, which effectively prevents dirt from entering and increases long-term durability. tradeinn Bikeinn
