What a crap article. Haha. I just ended up replacing 'fixie' with 'trucker hat' when I was reading that article and it makes just about as much sense.
I guess fixies have finally jumped the shark. I mean, first came capris, then everybody started wearing them, now fixies are new (within the past century), so I guess every starbucks sipping hipster is going to start charging around on brakeless track bikes when they're not fit enough to walk to the store for their menthols. I really doubt we have to worry about the brakeless track bike scene becoming super saturated.
