I'm not too worried about the quality of the stock wheels on whatever I get, since they are so easy to replace if and when they fail. REI is local, and I have a membership there so I've actually had the oportunity to test ride that exact bike, and it seems quite alright to me. The saddle is quite silly though. I change when I get to work so sweat and wet are not that much of an issue.
I assume, then, that you have the capacity to store this high-dollar bicycle indoors at all ends of your regular commutes?
I live at ground level so rolling the bike in and out of my apartment is a breeze. I also happen to work at a secured facility, i'd leave my bike outside with no lock and i'd not worry one bit. There is a fence, guards, cameras and everyone has an ID with full background checks and fingerprints and all! So at work the bike is more safe than it is at my apartment. There are also many other people that ride bikes so if someone were so silly as to steel a bike it might not be mine. In fact this past summer I saw someone park their supersix outside an adjacent building.
When i'm riding to and from the metro I use my ancient mountain bike that i'm not at all afraid to loose. Although I might try and sell it.
