Izumi Super Toughness Kai Single-Speed Chain

The Izumi Kai Super Toughness Chain was designed specifically for the Olympics with the USA Track Cycling Team. To work for these world class athletes, the chain had to be strong enough to handle their immense power while remaining smooth and fast. A slick new coating along with seamless bushings and rollers helped lower resistance by 10% when used with a high-performance lubricant. This new technology simultaneously increased hardness, durability, and corrosion resistance. If you are a track rider looking for the toughest chain on the market, look no further than the Izumi Kai Super Toughness Chain.
