I have been given a Christoff Australia bike. The bike has all original decals showing "Christoff Australia" and "Australcorse" "Adelaide, Australia" and "Jon Christoff" signature. Punched into the frame is a marking "Bullock".
I think it has been tinkered with as there is a mixture of running gear - campag record rear wheel, hub, gears, dura ace derailer.
Does anyone have any history re this bike frame etc. I am keen to find out a bit more about it.
