All three of these gave me a different frame size ranging from 57-61. I ride a 61 Roubaix comfortably and can't imagine being on anything smaller. The .67 inseam length puts me squarely at the low side of 57, but I'm 6' 2" tall. I'm glad I have a bike shop where I can walk in and the owner can more/less look at me and know what I need in all directions. More kudos for my LBS for taking the guesswork out of it for me.
