JT 1304 Twinstar Rear Sprocket

The core of the JT TwinStar is a lightweight aviation grade Ergal 7075-T6 Aluminium, precision made using state of the art laser cutting and CNC machining.

• The steel outer ring is heat-induction hardened to create a sprocket which will last up to six times longer than a standard 7075-T6 aluminium sprocket
• Fully heat treated for higher wear resistance
• Meet or exceed OEM standards
• Optimum design for light weight and strength
