Well, I got my Look 566 in S (53cm TT) and it was too big! Took it to my LBS and after tinkering a bit we all agreed I need a smaller size. So I packed it up and sent it back to the place I ordered from (hopefully it gets there unscathed).

They have an XS that has a 51cm TT and my LBS said that's what I should have ordered in the first place given my short inseam. Guess I need to wait another 2 weeks to get my bike, and just praying that this time it fits right!
