I'm racing again this season. This will be my 4th season racing cross (although my 1st season consisted of one race where I skinned my shin down to the bone tripping on a barrier -- season over!).

My race rig is a Ritchey Titanium Break-Away. I had raced Shimano Dura Ace in past seasons, but my road bikes are Campy so I just made the switch on my cross bike too (allows me to get rid of a lot of duplicates, like wheels, etc). I'm also running a PowerTap on my cross rig this season to collect some real data (haven't done that in past seasons).

Kitsune06, you don't need multiple bikes. A cross bike does it all -- throw road wheels on it and it's a road bike, if you've got generous gearing it's a rigid mtn bike, get a frame with eyelets for racks and it's a commuter! Or, just try some cross races on your mtn bike. Beginners are allowed to race on mtn bikes.
