“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 stock with anti-corrosion lubricant applied, or pre ultrasonic cleaned for reduced friction and greatest performance when lubricated with low viscosity race lubricants.

Ultrasonic cleaning disclaimer:

  • An ultrasonically cleaned chain will require lubrication to be applied immediately upon arrival with the customer. If left unlubricated the chain will begin to corrode.
  • Ultrasonic cleaning may add an extra 1-2 days to prepare prior to shipping.
  • The cleaning process may not remove 100% off all factory lubricants.
  • Some discolouration may occur to the chains plating. This is most noticeable on chains with gold plating.
