There is a cyclig culture, but there are also subcultures within it.

I'm very fortunate in my area in that there is a lot of overlap between the various groups within the cycling community- utility cycling, SSFG hipsters, commuters, roadies, alt bikes- you'll see all these at our Critical Mass ride tonight, enjoying each other's company and hopefully drawing a few smiles from the "cagers."

I've gotten sucked in to an extent into the local cycling community. They are the reason I joined Facebook- for some rides, that is the ony way to find out about them. Having joined FB, I've become friends (both on FB and IRL) with several people who like to ride. Even if you take the cycling aspect away, these are people I would enjoy the company of. Cycling, then, just becomes a rallying point and an ice breaker.
