Izumi Kai Super Toughness Chain - 1/8"
Izumi Kai Super Toughness Chain - 1/8" Info
The Izumi Kai Super Toughness Chain - 1/8" was developed in collaboration with the USA Track Cycling Team for Olympic competition — a brief that left no room for compromise. Built to handle the explosive power outputs of elite track sprinters, it uses a proprietary coating alongside seamless bushings and rollers designed to reduce drivetrain resistance by 10 percent when paired with a high-performance lubricant.
That same coating technology simultaneously increases hardness, durability, and corrosion resistance, making this a chain that holds up under repeated hard efforts without sacrificing smoothness. Whether you're racing on a velodrome or pushing a fixed gear through serious training sessions, the Kai Super Toughness is built for riders who ask a lot from their drivetrain.
