just built up a frame i was given, its a Ribble and made using Reynolds 531 competition tubing. The frame itself is very sound and i was wondering if anyone could give me some info on it ie what age it may be and how good a frame is it? It weights just under 23 pounds now built up. I am hoping it is a good frame as i would like to invest a bit of time and money into it and see what i can make of it.
