What are the differences between the Izumi chains?
Super Toughness NJS
Strong, tough and reliable, the Super Toughness V Track Chain never fails in races. It uses a special high-carbon alloy for the connecting pins—often used in low-friction ball bearings—which offers a 300% increase in durability compared to an IZUMI 401 chain.
Izumi-V is renowned among keirin racers for its strength and efficient power transfer and is of the few chains that meets the strict certification requirements of the Japanese Keirin Association (NJS).
