This innovative sprocket features a unique two-ring construction, optimizing both performance and longevity.\n\nThe sprocket's clever flat face design minimizes weight while maintaining a narrow profile, comparable to standard sprockets. The inner ring is crafted from high-strength Ultralight 7075 T6 Aluminum, ensuring a light yet robust core. The outer ring is made from nickel-coated steel, providing enhanced resistance to wear and corrosion. Through a precise manufacturing process, the outer ring is expanded at 200°C and fitted to the inner ring, creating a permanent and powerful fusion bond that guarantees the sprocket's integrity throughout its lifespan.\n\n### Key Features:\n\n \n- Hybrid Construction: Combines an inner ring of 7075 aluminum with a hardened steel outer ring for an optimal balance of low weight and maximum lifespan.\n \n- Advanced Manufacturing: Utilizes CAD design, CNC machining, and laser cutting with state-of-the-art technology for precision and accuracy.\n \n- Secure Interlocking Design: The precise interlocking of the two rings eliminates any potential movement, ensuring consistent power transfer.\n \n- Optimized Layout: Features a sector-optimized design that maximizes strength while minimizing weight.\n \n- Durable Anodized Finish: The inner ring is color anodized coated for added strength and extended durability.\n \n- Race Proven: Tested and proven on the most demanding sand tracks in the Netherlands and Belgium, demonstrating its resilience under extreme conditions.","weightGrams":null,"fitments":[{"make":"GAS-GAS","model":"EC F
