Can I use this for my sig?
Actually, I think elTwitcho is probably right. My guess was a slack chain, but I fail to see how that will affect the OP's speed. To make matters worse, the OP has utterly failed at communicating what his issue is. A crank can turn forward and backward, and wobble side to side. "Left to right" is pretty damn vague.
