As I was leaving my lbs at closing I saw a red 'GT' frame hanging from the ceiling with what looked likt a triangular sticker on the seat tube just above the bb which might have said '631'.
The seat stays went past the seat tube and were welded(?) to the top tube, which I have never seen before.
Questions. Is this a steel frame, and if so, is there a way to determine its age?
Since I would like to try a steel frame what are the odds that the components from my Trek 1200 would fit?
The sticker said $400.00. Is this a reasonable price?
If I go back to the lbs I would like to be armed with as much information as possible and have tried the search function and Google but can't find any info on frames that look quite like this one.
