The Izumi V is Izumi's high end track chain that truly delivers on Izumi's precision and quality. From Izumi's website:

"You won’t find a stronger, longer-lasting, or more beautiful chain than the legendary Super Toughness, made from pure Japanese steel. We use a special high-carbon alloy for the connecting pins—often used in low-friction ball bearings—which offers a 300 percent increase in durability compared to a standard chain. One of the few chains that meets the strict certification requirements of the Japanese Keirin Association (NJS), the Izumi-V is renowned among keirin racers for its strength and efficient power transfer. The proprietary surface treatment increases abrasion resistance and creates the striking contrast of gold outer plates against midnight-blue inner plates."
