  • What actually is the rules of NJS? I'm guessing the manufacture sends the Keirin body the component for testing and once they are happy it's up to standard, they have the manufacturer stamp each one?

  • Hey there. Pretty much.
    NJS certifies the product in two ways.
    Firstly, it's to make all races bikes and components equal and not give individuals advantages. This is to provide fair betting during Keirin races.
    Secondly it's about quality and safety. All parts need to pass checks to ensure their worthiness. For example, Vivalo lost their NJS licence due to one or two incidents of the fork crown detaching.
    Thirdly and what concerns us all most, it's just plain cool ;)
    Cheers. T
