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.
Available in 1/2x1/8 (NJS approved)
380g (1/8-inch pitch, 106 links)
