I need a little help. I am looking to buy or build, haven't decided yet, a cyclocross bike but haven't figured out exactly what size frame I will need. I ride a 06' Trek 2100 road bike in a 56cm and don't know what that translates to in a cyclocross bike. I am about a 32" inseam if that can help me chose a frame size. I have looked at a Trek that was a 56cm and it fit pretty good, but I was wondering if anyone could help me decide on a sizes for Fuji, Cannondale, and Kona. I found good deal on a Fuji, but need to find out what size I would need because I won't be able to get on it before I buy it. Thanks for any help in advance!
