I like to rotate all the pins in my chain by 90 degrees when the wear on the chain starts to reach the replacement point. I am trying to find a source of just pins so that I can use new pins after the old pins have worn too much. Maybe I will be able to find some pins that are 1/10000" larger in diameter so that they would compensate for some of the wear in the chain plates and rollers.
By the way is that bridge tall enough for bungy jumping.
