The fork mount bike rack will be fine for your carbon bike (just make sure you buy locks for the rack mounts (4) and the fork clamp (1). the roof mounted racks also come in a version in which you do not need to remove the front wheel. If you can't lift the bike up onto the roof rack (e.g. SUV), then I would suggest a hitch mounted rack that is similar to the ones you see on city buses. both Yakima and Thule offers this version and you don't have to worry about your frame rubbing up againt another bike.
