Maybe it is the lightest custom Brompton ever built with two brakes + multispeed.
     
    Many parts were custom made by myself, and it was very enjoyable during the past 6 months.
     
    It is very good for city commutes with this weight, and it is fun when riding on it.
    Here is some of the parts list:

    darimo seatpost and handle bar
    thm crankset
    extralite hubs with carbon rim 
    Extralite brake lever
    Ee brake
    gelu k3 saddle 
    ybn titanium chain
    Sliverock carbon triangle
