If you are 5'10 you should probably be on a 54 at the smallest. Have you gone to the shop and test rode them yet? I'm about 5'11 and I used to have a caad size 54. It worked for me with a long 120 mm stem but it still felt a little cramped especially if I was riding over 20 miles. I would bet you would be between a 54 and 56 depending on your proportions.
