I picked this so-called GIOS up from the LBS today. I knew it wasn't a GIOS, but it looked good enough to strip of its inappropriate decals and flip:
What got me completely by surprise was what is hidden under the repaint - a 1984 Raleigh Gran Course (or Competition 12, the frames are identical), exclusive to the U.K. market:
I knew the combination of Prugnat P4 lugs, sloping fork crown, and fastback stays felt familiar (the Panasonic Team Professionals, specifically), but I just couldn't place it until I checked the catalogs again.
It's a pretty decent frame, if not that well cared for (one of the seat stays had been curved inwards, which pulled both stays out of alignment - some careful cold setting rectified the problem to the point that it's impossible to tell it was ever damaged to begin with), and the amount of brass on the fastback cluster leaves a bit to be desired, so I'm going to have Mike Terraferma fill it a bit before I do anything else.
It puzzles me to no end why anyone would consider turning something as nice as a Raleigh Gran Course/Competition 12 into a GIOS - after all, they're both nice bikes - but I dare say that's the appeal of the Italian marquees coming through.
