So... no burrs or anything in the way? If the housing was meant to end where the cable enters and exits the top tube, (cable housing stops) it
should be obvious. Unless somebody altered it at some point. Otherwise then the cable housing
should go all the way through the top tube, unless there's a burr or something. I really doubt Colnago would design it so that it required something other than any standard, ordinary cable housing. So it really has to be one thing or the other. You don't need some obscure type of housing. I was hoping a owner of that vintage of Colnago would chime in with some insight. Maybe try posting this in the C&V forum.
