You won’t find a stronger, longer-lasting, or more beautiful chain than the legendary Super Toughness,
This variation is for the narrow drive train1/2 x 3/32
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.
