True about the bike size but I did a lot of research/self measurements before I bought my CAAD10--52 CM--I think its good for me---I have just been trying to dial in the seat height, fore and aft positon and then dropped down 3 spacers on the stem---so far my legs feel good, hand numbness gone, working on smooth higher cadence---I ride mostly on the hoods-not comfortable in the drops yet--will probably actually get fitted when I have more time on the saddle
