Frame material: You mean that there's a material other than steel that actually works for commuting. Say it isn't so! Steel is reel.

Rivendell: I can hardly afford to drool over their website.

Brakes: The kind that fit on the bike.

Bling: Real cyclist=somebody riding a bike. Hello, we don't say that somebody isn't a "real" driver if they don't have a helmet, race chassis and a number on their car... they qualify if they have a steering wheel in front of them. If you have a saddle under your butt and pedals under your shoes, you're a cyclist.

Brooks: I have one. I like it. Nuff said.

There are others, of course. Like lights vs reflectors vs stupidity.

Conduct: A bit of the driver, and a LOT of how you respond.
I respond like there's a 6000lb beast of burden bearing down on me and it does whatever the idiot behind the steering wheel (see "driver" above) tells it to.

I have now successfully typed away several minutes while I really should be working. . Of course, as strong as my opinion is in this post is, it's not terribly off the mark... I know that for a fact.
