Scope R4.g Cl Disc Tubeless 2026 Gravel Wheel Set. Unleash your gravel potential with the SCOPE R4.G CL Disc Tubeless 2026 wheelset. Engineered with the same DNA as the award-winning Artech series, these wheels deliver best-in-class aerodynamics and race-ready weight. At just 1439 grams, they offer exceptional lateral stiffness and uncompromising durability. The 28mm internal width hookless rim is aerodynamically optimized for 40mm tubeless tires, providing a perfect blend of rolling resistance, efficiency, and comfort. Enhanced by a labyrinth system for superior dirt protection and long-term reliability, the R4.G is built to conquer competition and daily training alike. The new R4.G is derived from the award-winning Artech series and built from the same engineering DNA. This wheelset delivers best-in-class aerodynamics, a race-ready weight, and durability designed to last.Best in class aerodynamics at a race ready weight:- By adopting the proven rim profiles of the Artech series (without the Aeroscales) the R4.G delivers best in benchmark-tested aerodynamic performance. With steel spokes and a total weight of just 1439 grams, it is the ultimate gravel wheelset, built to excel both in the heat of competition and in the demands of daily training.Beyond its low weight and aerodynamic advantage, the R4.G combines exceptional lateral stiffness with uncompromising durability. Its 28 mm internal width hookless rim is aerodynamically optimized for 40 mm tubeless tires, offering the perfect balance of rolling resistance, efficiency, and comfort. Meanwhile, the mechanical labyrinth system protects against dirt ingress, ensuring long-term reliability and consistent performance.Labyrinth system:- The R-series hubs feature a mechanical labyrinth system, effectively blocking dirt from entering and increasing long-term durabilitySpecifications:Rims Front:- Rim height (mm): 45- External rim width (mm): 38- Internal rim width (mm): 28- Tubeless (ready): Yes- Hooked: No - hookless- Optimum tire width (mm): 40- Tire width compatibility (mm): 35-65Rims Rear:- Rim height (mm): 45- External rim width (mm): 38- Internal rim width (mm): 28- Tubeless (ready): Yes- Hooked: No - hookless- Optimum tire width (mm): 40- Tire width compatibility (mm): 35-65Hubs Front:- Hubs: Scope R-Series- Bearings: 2 X 61803 - SKF- Engagement system: - Axle System: 12 X 100- Brake Interface: Centerlock- Labyrinth system: Yes- Spokes: Front- Spoke count: 21- Spoke type: Sapim CX-RayHubs Rear:- Hubs: Scope R-Series- Bearings: 3 X 61803, 1 X 61903- SKF- Engagement system: 36T Diamond Ratchet SL- Axle System: 12 X 142- Brake Interface: Centerlock- Labyrinth system: Yes- Spokes: Rear- Spoke count: 24- Spoke type: Sapim CX-RayTechnology:Algorithm Enhanced Aerodynamics:- The shape of our rims is defined by our Algorithm Enhanced Aerodynamics (AEA) technology. This algorithm optimizes the most aerodynamic rim-profile guaranteeing optimal aerodynamic performance.Lightweight design:- With our Local Reinforcement carbon technology, we've increased the number of carbon layers around the spoke holes on the inside of the rim. This way we significantly reduce weight while preserving strength and stiffness.Perfect tire-fit:- The unique geometry of our Scope Tubeless System ensures easy mounting, direct inflation, long-lasting pressure and compatibility with all clincher and tubeless tires.Lightweight and durable:- The Diamond Ratchet SL system is made from titanium and finished with a diamond like carbon coating. This results in direct engagement, improved durability, and a significant reduction in weight. tradeinn Bikeinn
