How do you go about fitting a cyclecross frame?

Beats me.........

Why not the same as your road bike?

I know you've been to American Cyclery , right? they have a real good slection of cross frames that they make.

same as a road bike, or a little bit smaller.

Anyways,this is what I had in mind http://stores.yahoo.com/cyclocrosswo...onslframw.html I have enough parts to put it together so i just need the frame unfortunally they don't have the size i need .i migh have to get a Colnago

You should run a smaller frame then your RB.

the best way to size a bike is (contrary to popular belief) by the top tube. by finding the actual tt length (stem plus tt) and comparing it to what you're most comfortable with, you can get a good idea of what frame sizes to start trying out. bikes have adjustable seat posts for a reason. basically you'll be happiest with a bike that has a front-center length that fits, not just a frame to fit your inseam. i had my 'cross frame custom built by salsa and ended up going with a front-center that was almost an inch longer than 'normal'. i ride a 51 cm with a front-center length the same as a 53/55 cm. now here's where it gets tricky, the salsa cross frames had a sloping top tube, so a 53 cm is really the same as a 51cm road frame with a non-sloping top tube. so, my cross frame is actually close to 4 cm smaller than my road bike. my 'cross bike actually measures closer to my mountain frame than my road frame. one more thing to consider, you're rarely gonna be in the drops for very long on a 'cross bike and most 'cross riders tend to rotate the handlebars upward so the flats are either perfectly horizontal or even higher. this means you'll want to run a little bit shorter stem than normal to still reach the drops, which means you'l either want to have the frame's toptube length make up for that, or move you're seat forward or back on the rails. can you tell i used to work at a bike shop? frame sizing is a mysterious art! hope this helps...
