    Outfitting older bike that's a bit small

    I have this '82 Univega Gran Turismo which I like a lot or at least it's all I got. I would like to get myself into doing some longer tours, so I want to get the bike to fit me well enough so that it isn't going to pose any risk of injury due to positioning, etc.

    The problem is that the bike is a 54cm frame, and I'm 5' 10" with a 86.5cm inseam. That would lead me to believe I'd be better off with a 56 or 58. However, my LBS says my reach to the bars looks pretty good and so do my legs and stroke, but the stem could come up another inch, which requires me to buy a new stem, and while I'm at it I'll probably buy some other things like wider bars.

    So do you think the bike has the ability to be a good fit for me if I bought some new parts? I'm not sure what sort of differences the geometry of a taller bike would have versus a smaller bike with a taller/ maybe longer/shorter stem and a seat post with generous setback. Are there any in the way as far as fit goes?

    I also want to change out the 27s for 700cs at some point, too, which will of course lower the bike 4mm? Will there be any other notable effects from that change?

    I like the fact that the bike is a lugged steel frame, and if I could find another decently priced one my size , I would hop for it. I'm asking you guys if you think it could work, because the guy at the LBS told me not to put too much money into the bike, and that the newer tech is far better. Which is likely true, but I'm fine with what works and have a thing for the old style.

    Thanks for your input.

    I was in the same situation. I'm 5'10" with a 34" (~86mm) inseam. I had a 21" (54mm) Univega Viva Sport, and I could tell it was too small. If I were you, I'd find a store that stocks some kind of touring bike, and test ride a 56, 58, and/or 60. I did just that, and ended up buying a 58, though I think a 60 would have worked too.
