All the people who talk about all the great shops in Colorado are neglecting one point...if you happen to live on the Southeast side of Aurora there's not much. There's the Treads mentioned in the OP. On the northern end of Parker there's a new shop (Creekside) that opened recently that's pretty small (specialized dealer but also seems to deal in the vintage stuff...and campy). I don't know much about them yet. Then there's Bicycle Village and Adventure cycling. I rarely buy stuff at the bike shop unless it's something I need quickly or on a crazy good sale. But I've been to Adventure a few times for their service and I've been pretty impressed. Bike Village boasts that it's the biggest bike shop in the US or something like that, sometimes you can find good deals there during their sales events. I still buy most things online. Bike shop is nice when I'm stumped on a problem and can't fix it myself like I usually can.
