My cyclocross bike, an older Orbea terra, was built to race and not much else. It comes with one bottle cage mount, a tall bottom bracket, a steep head tube, the original brakes were pretty mediocre, and the gearing range was short. I used it as a road bike for a summer, and found the ride to be pretty harsh even with 28mm tires due to a lack of frame compliance (my road bike, with the same wheels/tires/pressures, rides much better). The plus side, of course, is it's light and fast and handles well on a race course. But over the years I've made some changes that have improved both comfort and performance.
