All good points. I'm about 5'10" w/ 30" inseam, and size the bike by ensuring there is 0">1" of clearence when straddling the bar.
The 5200 has dings and scratches but appears to be in otherwise good condition. I'm buying more for the weekend ride and weekly commuting, and don't expect to be racing--although I'm not counting it out.
My primary goal is to get a good platform (frame/fork/wheels) that I can build on by upgrading the less expensive components.
