I don't think it's very fair to bash on the very expensive road bikes. These guys buy those bikes so that they can ride 100+ miles on an average day. They don't use these bikes to commute either. It's simply that their hobby is to ride and they find a great joy in it. Many compete too. The burning sensation, heart ripping out of your chest and gasping for breath as you pump your body's 2 pistons up 2000 feet of mountain. I know it sounds terrible but it's what some love. It's very different from what we use our bikes for.
Anyway. In my area, I've gotten all sorts of comments on it regarding at as "that's cool!" It's never been seen around here. This is primarily a college crowd so things like this are typically well recieved. So far my bike has been very reliable too, so that helps
I would say it's dependent on your area.
