Izumi KAI Super Toughness Track Bicycle Chain - Silver

This chain, specially developed for the Olympic Games in Tokyo and tested in collaboration with USA Cycling, features a very smooth, highly functional new coating on the plates, seamless bushings, and rollers, which is said to reduce resistance and air resistance by up to 10% compared to the conventional V Super Toughness Chain when used in combination with a high-performance lubricant.

This new technology also increases hardness, durability, and corrosion resistance.
