It's a subculture and it has gazillion of subcultures that often contradict one another to a great degree. You don't need to look far: road cyclists and mountain bikers. Each completely different and each divided into further subcultures. And cycling isn't really special in this regard: any sport or social activity is a complex subculture. Try RC helicopters forum or computer overclockers forum to see what I mean

I take an issue with trying to identify with "subcultures". A single individual may identify themselves with several subcultures or even have their own that is a mix of others. I don't know what I am I believe that people who identify themselves strictly with a single subculture, are either limited or wrong and confused about their identity. I'm a utility cyclist, a commuter, a touring cyclist, I was a XC mountain biker a road cyclist for a while, I even rode singlespeed for a year or two. I'm also a computer geek, hiker, camper, amateur photographer, amateur musician, I like Star Wars and anime, I have eclectic taste in music from techno, trance, electronic, eurodance to metal, reggae and southern rock. I like Chinese and Japanese food an pizza as well as burgers and fries I was an avid computer gamer, tweaker and overclocker and many other things. My attire lacks any style, it's a mix of casual, urban, cycling, outdoor, work clothing regardless of what I do. I stopped trying to categorize myself and others. We're all complex individuals, way too complex top put in a single drawer.
