IZUMI Super Toughness Chain 1/2x1/8 V Gold 106L

In stock (2)

There are few components that carry the fabled NJS stamp. From the Tachikawa Velodrome to the streets of New York, this chain reigns supreme as the quietest, strongest, flashiest, best track bike chain available.


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 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 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. The proprietary surface treatment on pins increases abrasion resistance and creates the striking contrast of gold outer plates against midnight-blue inner plates. 1/2x3/32 model is now often used in BMX racing.

Available in 1/2x1/8 (NJS approved) and 1/2x3/32 versions

380g (1/8, 106 links)
