I really don't understand cross cycling myself. They just seem like hybrids with drops and I really can't stand hybrids since they're slower than road bikes and not as tough as mountain bikes. But oh well, the races look like more fun than mountain biking or road races so I can dig it.
My Ridley, with road tires, is faster than any of the road racers I have owner, I'll be riding a full road race season on it next year, then a full cross season. No reason to have 2 bikes when one will do it all.
