I thought I had seen this idea before but couldnt remember where.. should make a sweet and fairly uniqur ride. as far as the hanger goes,I was worried about that,in case I ever wanted to switch back,but I think its buggered up when they installed the shimano derailleur. dont they have different threads? although it could probably be repaired.
