What's with fixies. Seriously, those are pretty much the only bikes I see people riding now. There are no advantages of riding a fixie!! Sure, you look like a PBR-guzzling hipster, but I'll be the one laughing when you fools are going 30mph downhill and I can actually brake.
The only possible reason one could justify their fixed-gear riding for is that the frames are ridiculously light. That's it.
Hi, I have gears. And brakes. And I can go just as fast as you.
