In freestyle sports like skateboarding, snowboarding, and biking, you draw alot of blood. But thats what makes these sports fun. Maybe a friend asks you how you got a scab or your arm, and you say you were trying to land some insane trick and a conversation is started. I dont know if band aids are part of the freestyle biking culture, but scabs and blood definately are.
as a side note, my buddy runs a website that you can purchase bike parts off of and it is coincidentally called http://www.shopcultur.com, and they ship locally out of Richmond! check it out!
