For all you CAAD lovers... I know this is a "cyclocross" bike, but do any of you use this as a pure road bike? Looking at a CAADX for roughly $500, which is enough to make me look at it. I was considering a Specialized Allex or a Trek Alpha - which are more pure road bikes, but I like the disc and other options the CAADX has. I probably wouldn't use it for off-roading too much, so probably mostly road/blacktop and long trips use. Any input is appreciated, thank you!
