JT Twinstar Rear Sprockets

This Steel / Aluminium hybrid sprocket has been made with a lightweight aviation-grade Ergal 7075-T6 Aluminium with a heat-induction hardened Steel outer ring. While the Aluminium core creates a lighter sprocket, the Steel outer ring creates a longer, more durable sprocket which can last up to six times longer than a standard 7075-T6 aluminium sprocket.
