I like my Trek 750. Sturdy, versatile. Not fast, but works well for the 50 to 60 mile rides I do on weekends.
On a typical ride, like this past weekend, I'll be riding roads, mup's, gravel trails, single track and rough city streets. Wouldn't want to try it on most road bike.

That said, I have started eyeing some of the road bikes at my LBS.
Soon be time for a new toy.
