I have the 2011 model, it's tiagra shod, and I've used it for racing so it's been upgraded a bit. The FSA cranks & BB were swapped out for Shimano (FSA are rubbish and it fell apart very quickly under harsh conditions), the brakes have been upgraded (the originals were like blocks of cheese) and the saddle (the rails broke on the original after about 1yr). Top bike for the cash. When it dies I'll swap it out for another CAADX, but with disc brakes...
