Hello gentelman,

So Ive been communting on an old MTB 13 miles everyday and Ive done it for about a year now and Im just now starting to think that a road bike would make my commute a bit easier. I see alot more road bikes on craigslist in my area than MTB. If the frame on my rock hopper is a 23" then I should look for a 58cm road bike? I intended to test ride before I buy but I dont want to waste my time on bikes that are too far off. I appreciate if anyone can shed some light on this..
