Specifically designed for the Tokyo Olympics and tested in partnership with USA Cycling, this chain features a very slick, highly-functional new coating on the plates, seamless bushings and rollers which is said to reduce resistance and drag by 10% compared to the traditional Model V Super Toughness when used in combination with a high-performance lubricant.

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