Specifically designed for the 2020 Tokyo Olympics and NJS certified for Japanese Keirin racing, this chain features a very slick, highly-functional PTFE treatment on the plates, bushings and rollers.
This reduces resistance and drag by 10% compared to the traditional Model V Super Toughness when used in combination with top quality chainrings, cogs and a high-performance lubricant, while also increasing hardness, durability and corrosion resistance.
