I'm coming up on 2 years with my '12 CAAD 10 4 in a couple of weeks, this was the best bicycle purchase decision I have made in a long time. No problems at all, swapped the stock 23 Lugano tires for 25 Gatorskins, put on a K-Edge chain catcher, added a wedge seat bag for the tube, CO2 and a multi-tool and keep the bearings cleaned and greased properly. Made a 4000 + mile year, 230+ hours riding time. If you are thinking about buying a CAAD 10 of any level, do it.
