The JT Sprockets JTF1381.15 sprocket is designed to replace the toothed element of the secondary transmission on 520 chains. Made from SMC420 steel, this standard 1381 sprocket offers a robust construction aimed at riders seeking reliability and longevity for their chain and sprocket.

• Material: high-strength SMC420 steel
• Number of teeth: 15 teeth (sprocket)
• Chain pitch: 520, compatible with 520 transmission
• Machining: CNC machining for precise finishing and optimized contact with the chain
