R4 Road | Outstanding All-rounder AEA Optimized Aerodynamics The rim profile of our wheels is developed using our Algorithm Enhanced Aerodynamics (AEA) technology. This algorithm calculates the most aerodynamic rim profile to ensure optimum performance. Diamond Ratchet Ultra-light and durable The hubs feature our Diamond hardened Ratchet engagement System for direct engagement, improved durability, and a significant reduction in weight. Local Reinforcement Lightweight With our Local Reinforcement carbon technology we increase the number of carbon layers only around the spoke holes on the inside of the rim. This way we significantly reduce its weight, while preserving the strength and stiffness. Tubeless system Perfect tire fit The unique geometry of our Scope Tubeless System ensures easy mounting, direct inflation, long-lasting pressure and compatibility with all (tubeless) tires.
