  • Description:
    In the 1980s, Frank Kirk, an Engineer who worked in the aeronautic industry as well as the automotive industry, had a great idea.
    To design and build a bicycle frame from cast magnesium.
    Magnesium is a light structural metal, which can be found pretty much everywhere in the earth crust and in water.
    Kirk claimed that one and a half cubic meter of seawater contained enough magnesium to cast one bicycle frame.

    His concept for the frame was calculated by computer programs, making it in fact one of the earliest CAD-bicycle designs.

    The story of the production with all its ups and downs is actually well documented and a fun read. Here we will concentrate on the qualities of the frame which has a pretty stiff main part for its time with elastic rear stays. It proved to be tough and well rideable. So much so, that the Dutch Team TVM used it in the Tour de France.

    If you like the utterly technical approach to building a frame, then this is probably the perfect frame for you. An icon of bicycle design!
