I am looking to race the local cross circuit in oklahoma this fall when i move there, courtesy of the us army once again! However right now i'm running my road bike with full ultegra drive train and componets, ritchey prologic pedals, and mavic open pro wheels. Any suggested componetry changes for going cross other than the tires!? I'm particularly concerned about the pedals and perhaps the gear ratio..what should i be running on a cross bike?
how are you gonna get the CX tires to fit? nmdustin73

Not too hard, except for the tirescory

Years ago, before I had a mountain bike, I set up an old Trek tourer as a substitute. I didn't even know it at the time, but it was very similar to a cyclocross bike.
The thing that made the most difference was the tire swap, of course--but the Trek had canti brakes and a LOT of room between the stays. It fit 700x35 knobbies easily (I'm still using it as a singlespeed with 700x40s, and I could go bigger).
You don't mention what kind of road bike you have, but most modern frames have trouble with anything bigger than a (labeled) 28 or 32mm tire. Usual problem is clearance under the short-reach brakes--my Allez will JUST fit a 700x32 Pasela (25mm true width), but nothing bigger than that, and Ritchey 700x30 cyclocross tires won't go. I'd see if a shop will let you mount a cyclocross tire to be sure it fits before you spend money anywhere else. check front and rear; they may not be the same.
