It's too bad that they lost your order!! I have also heard from my LBS that Trek was backed up with orders. Maybe you could look into another bike. I know that Specialized has a WSD road bike, the Dolce. I think they have one similar to the Trek you wanted.

I'm 5'2 as well and I seem to fit well on the smaller men's frames. I have a Cannondale in a size 49, I also seem to fit on a men's Trek 2200 I believe it was a 52, but it may have been a 51.

Good luck!!
