Two additions to my previous posts:

1) I was surprised to find the Bontrager saddle that came with the 7.2 just fine. It's still on.

2) I have seen many people with the Sirrus and it seems to me like it's pretty much the "same bike" as the 7.2/3 fx. Also looks like a great bike. My testimony in favour of the Trek does not mean anything about the Specialized.
