Ooh, you should check out a 44cm Redline Conquest, too! That's what I'm on for cyclocross and I LOVE this bike--it's even sweet on the road with slick tires! I have the basic Conquest, but my LBS swapped-out SRAM Apex for the low-end Shimano group that was on it.

I think pretty much any shop can order Redline, even if they don't stock the brand. Nice bikes. My LBS is just getting in Ridley for 2012, but I scored a '11 Redline for such a deal, since my LBS actually had one in my size and wanted to make room for new models.

Cannondale really makes some nice cyclocross bikes, too, as does Gunnar. I've got 3 friends on Gunnars that they use both on and off-road.

I'm only about a half-inch taller than you and my crotch-to-ground inseam is 30".
