Dh recently bought a 2007 Roubaix with a mostly carbon frame. It came with several decals (swooshes and chevrons) and they are, to put it kindly, not very impressive; the bigger ones look like they are about to peel up and almost all of them have a "crackled" look to them that I don't think is intentional. This leads me to believe that either they don't stick very well, or that they are very difficult to apply (even for the pros).
