I have a 7.5 (just of bit of an upgrade, but very similar) It really stirred my passion for biking. I do believe the wonderfully friendly and not at all pushy people at the bike store put me in a size too big. I feel a bit stretched out from seat to handlebars.
So, my recommendation: yes, its a great bike. Lots of fun and fast. But try to figure out what size you should have before taking home whatever is on the showroom floor. I know, that's the hard part. Good luck and happy shopping and then, happy biking.
