Good info. Thanks guys. When I was shopping for my Defy, the LBS initially put me on a M frame. I'm 5'7.5 with a 31" inseam, but I've also got short arms for a guy my size. I felt a bit stretched out on the M, so tried a S and felt more comfortable on that frame. However, my seat is slammed back as far as it can go. Now that my body has gained more flexibility from riding, I sometimes wonder if I should've just gone with the M frame instead. Then again, I suppose I could also try flipping my stem and removing some spacers to effectively lengthen my reach.
