Hey everyone this is my first post on the forum, and I come pleading for some guidance! I've recently started the habit of cycling to work on an old rusted bike and I now want to upgrade to a better bike. I've been browsing craigslist and I've come upon two possible options http://miami.craigslist.org/mdc/bik/3722305291.html (i talked to the guy down to 250) and http://miami.craigslist.org/mdc/bik/3715938516.html which the seller is willing to haggle on. Could you guys give me some advice as to what to look for when purchasing a road bike, especially a vintage one? Also I believe the frame size im looking for is somewhere between 55-58cm.
