I just upgraded to a CAAD10 in April. It's my do-all bike. Just did a hilly century last weekend and then a few days of commuting during the week.

My CAAD10 was a warranty frame replacement. I put tons of both commuting and recreation miles on my CAAD9 during the four years I had her. Frame died of metal fatigue at the bottom bracket. Best I can figure out is there wasn't such a great match between the crankset and frame, which caused the failure. It wasn't my weight. C'Dale came through and replaced it.
