You won’t find a stronger, longer-lasting, or more beautiful chain than the legendary Super Toughness, made from pure Japanese steel. Izumi uses a special high-carbon alloy for the pins—often used in low-friction ball bearings—which offers a 300% increase in durability compared to a standard 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.
Sweet chain
Izumi gold njs has been the strongest chain I’ve tested on single speed tall bike applications. Bikesmiths with the best pricing and fast shipping
