I just got this bike. I love it. I came from MTB and find it to be just fine. I run the tires with a little lower pressure and have a nice comfy seat. DO NOT get rid of this bike. It makes me want to ride again and again.
I think it will be one of the best selling entry levels of '09.

By all means DO get yourself fit as that would make any bike uncomfortable.

For all that talk of stiffness and rigidity. They are pretty subtle differences. It doesn't feel like you're riding an iron block down the street or anything but there is a nice road feel.
Can't recommend it any more!

Good luck with the recovery.
