I'm just wondering if anyone has any general advice, mostly related to the style of your bike and whatnot. A list of guidelines, basically. I've been lurking a bit and people seem to criticize others for things I don't really understand. General style tips on what not to do with: saddle angle, bar angle, drop, etc. would be nice, but any little hints would be appreciated.

I realize that most of the stuff is common sense, but I'm just asking for clarification. What makes you cringe when you look at a bike? Or what are some behaviours on group rides that are generally frowned upon?

Thanks for tolerating my lack of knowledge on what seems like second nature to most of you
