I've been cycling for about 3 years to get around but on a mountain bike. I'm still gonna use it for school and such but I wanted a road bike for the longer journeys. Because they run for much more than mountain bikes, is this a decent deal? http://miami.craigslist.org/mdc/bik/1083791143.html I know a steel frame is heavy but I'm not looking to race; I'm just looking for the something that would be better for going higher speeds and longer distance than a mountain bike. Also, I am only 5'3" so I am not sure if the measurements would suit me, please inform me! I currently own a Scwinn Ranger that I bought at Target about a year ago. Thank you for your time.
