When you become a cyclist, you become part of a special culture. This culture has its own slang and there are multiple subcultures. It is possible to belong to several cycling tribes. What you are wearing and riding will identify you. By day, I am a commuter cyclist with a sensible hybrid bike. I wear hi-vis clothing and use helpful panniers. At the weekend, I like to get on my road bike and put on my lycra. Occasionally, I put on other clothing and ride my cyclocross bike.
I love this blog post by Michelle Arthurs: 36 odd things only cyclists would say. (On the now-defunct Evans Cycles blog).
If you can’t identify the different groups of cyclists, then this blog post will help you out: Cycling Tribes: what sort of cyclist are you?
