The JT TwinStar Sprocket is a high-performance steel and aluminium hybrid sprocket, designed for strength, durability, and reduced weight.

• Lightweight Core: Crafted from aviation-grade Ergal 7075-T6 aluminium, precision-engineered using advanced laser cutting and CNC machining techniques.
• Durable Outer Ring: The steel outer ring is heat-induction hardened, providing exceptional wear resistance and a lifespan up to six times longer than standard 7075-T6 aluminium sprockets.
