when I was BMXing I used to wear through heavy duty BMX/skate shoes a lot. You have to pivot on the pedals a lot to get in positon/balance, and the pedals have essentially metal spikes/pegs on them. you see the connection.
i think its similar with fixies, but less so. pussies
just landed a new job that was a 20% raise over my last one, and an apartment that is $700 a month less than my old one. gonna use the extra $$$ for food and travel, and maintain current koppage levels. After I buy this henrik vibskov cardigan of course..
