The 7000 sits you pretty upright, as does my old Schwinn Woodlands MTB. Fine for putting around the town, but I dont like the handling one bit. My Sirrus handles like my mountain bike, quick and nimble! Bikes that are pretty upright are not designed for much speed. Of course, I am more comfortable doing high speeds on my mountain bike over any other bike. I have had it up to 50mph and felt fine, The road bike I had (specialized allez) I got up to about 40 and was very uncomfortable.

Each person is comfortable with handling on different bikes. Maybe your more comfortable on a mountain geometry bike rather than a comfort/hybrid?
