(One place INSISTED I was a small, another INSISTED I was an M.) It's all down to Giant's bizarre sizing schema, and their ideas of what someone our height should fit, never mind the length of our inseam or length of our arms.
Anyway, I ended up, happily, with an M/L Defy--"effective" top tube, 54cm-- and that's the size Anyroad you need to be trying. In any other brand, you'll probably need a 54, as I do.
Good luck, and keep us posted!
only resurrecting this thread as I found this to be wrong information and wouldn't want people to read it wrong if they had a similar fit question. The M defy is more the equivalent to a 54, while the M/L the equivalent to a 56. The M/L does NOT have an ETT of 54.
