Hi guys, this is a long, selfish question but any help is appreciated. Who knows, maybe some of the info will help someone else out here. Also, I know this has been asked before, but I have searched and can't find any definitive answer.
I am 5' 10" with about a 31" inseam. I like to ride a 56cm road bike, because I can keep the seat real low and stretch my body out. I also like to be level(ish) with the handlebars.
So now I want a cyclocross bike. Someone one town over is selling a 2005 Kona Jake for $400, which I think is a pretty good deal. He has no clue about bikes as it was not his originally, but he was told by someone that gave it to him that it is 57cm "from center to center." In 2005, Kona's frame sizes did not include a 57cm, just a 56 and 58. So it could be either of those.
But I don't know whether it is worth it to even drive an hour and a half out there to take a test ride. I have heard/read that cyclocross bikes run larger for their size but I don't know why. Is it because of the extra clearance on the ground? If I ride a 56cm road bike, is there any chance that I will fit on this bike with the seat all the way down?
I know that I won't know until I try it, but does anyone out there with any experience know that this is just a mismatch? Also, can someone tell me why cyclocross bikes run so much larger?
Thanks for any help to solve the mystery of buying a used bike.
