It takes all kinds.
I do see an attitude change depending on what I am riding. If I'm on my $5 1970's super sport I get all sorts of lies. Like his 180 psi clinchers. They were marked 130 just like I knew they were (I have 6). Or the guy who hates Litespeeds because they are a waste of money. But then If I'm on one it's a different story. These kind of people are everywhere not just in cycling. There certainly seems to be a lot of them on high end road bikes. Maybe it's because it's easier to afford a super high end road bike than a super high end car? So there's more of them in relation to the total population???
