Been a while since I rode and even in my riding days I was no mechanical genius. I've broken maybe 6 or 7 bmx chains in my entire life. Now I have broken two in a week. My question(s), before I go off in the BS, is what rider error could cause my chain to break? I have done no tricks other than hops onto/off of low curbs, it seems to happen when I stand and pedal. Is there something about my bike? No alterations yet, fresh out of the box. http://www.stolenbmx.com/zeke26 What mechanic error could cause a chain to break?
