Some hipsters are dicks, some roadies are dicks. It's a sausage fest out there. I'm from OC so I've definitely seen my fair share. It's mostly the teenagers that talk ****. But you can't expect much from them. Kids are kids. I wouldn't worry too much about "get some gears". At least you don't get called a "fixie ***" by bros in their raised 5mpg monster trucks every time you roll into the street.

I ride a fixie... with mountain clipless shoes and a helmet. Sometimes I can even be seen with a bookbag on my back... Rarely even with a T-SHIRT on!!!

I met one of these hipsters(he looks lie one of the more grungy ones) on my commute. He was ridding real fast and blew past me. I started to hammer and keep pace with him. He told me he never sees guys with loaded panniers and racks keep up. And then I died because I never hammered like that with so much extra weight. Maybe I'll see him Wednesday as I have only seen him on Mondays and Wednesdays
