I am getting looking for a vintage (1980s) steel frame to put together a city bike. I have a size 58cm Trek road bike now, but I need one I can lock up outside.
I am putting straight handlebars on it.
Do I get the same size or, because the bars are straight and therefore I won't be stretched out to the hoods, do I get a longer top tube so the bars are farther away?
I'm not sure I'm being clear here, but the issue is with the straight bars is the frame sizing the same?
thanks
