I was having a blast cruising around on the new cruiser, UNTIL - my bbr tuning one inch sprocket adapter has slipped enough that it broke a spoke and bent 2 others. Made it home safe but noticed wobble in wheel. I'm not going to ride until I fix the wheel. I've heard talk of shims, old bike tubes, spark plug feelers, coke can shims, washers, etc. to make your own spacer... Can anyone recommend what they may feel is best for this situation to shim up? Seems like this is the weak and critical point in my build. Would like to make it safe and secure without question.
