Izumi Model V Super Toughness chain

Made from pure Japanese chromoly steel, this is THE track chain. 

One of the few chains that meet the strict certification requirements of the Japanese Keirin Association (NJS), the Izumi-V is renowned among Keirin racers and track riders for its strength and efficient power transfer.

A special high-carbon alloy is used to produce the pins, often used in low-friction ball bearings, which offers a 300% increase in durability compared to a standard chain.
