Developed over five years, this sprocket offers superior lifespan compared to conventional sprockets. Its unique flat face design minimizes weight while maintaining a narrow profile, comparable to standard chainwheels.\n\n**Key Features:**\n\n \n- Construction: Combines a high-strength Ultralight 7075 T6 Aluminium inner ring with an Electroless Nickel Coated steel outer ring.\n \n- Bonding Process: The steel outer ring is heated to 200°C and expanded before being fitted to the aluminium inner ring. This creates a permanent, lifelong bond between the two components.\n \n- Durability: Designed to be the most durable off-road sprocket available.\n \n- Weight: The unique flat face design contributes to a lightweight construction.\n \n- Profile: Maintains a narrow profile, similar to regular chainwheels.","weightGrams":null,"fitments":[{"make":"GAS-GAS","model":"EC F
