how come you cant use some from a 70s roadbike?
The DT on the Kaffenback might be a bit fat - there are some variations on modern steel tube diameters. I'll have to email Planet X to ask them the tubing diameter. 70s road bikes have quite skinny DT's, f.e. Reynolds 531 downtubes typically measure 28.6mm.
