• Any ideas on who may have built this frame? All I know is the frame is lugged using Mervex luggs and the dropouts are Binelli. The dropouts also have GP Design written on them.

    Under the BB there is stated 122556 above this the number 590306222E66 the the name Nervex.

    What do they all mean, and id like to know what year it was produced and by whom?

    Thanks in advence.
