Sorry for the confusion. YES - it has dropped the chain twice to the outside. I'm concerned about that and addressing it (hopefully) with some adjustments. But yeah, I'm more concerned about the potential for damage when the chain drops to the inside and passes the spider. That happened to me last year and to a buddy last week. Fortunately we were 2 miles from the end of the ride. He was on his second ride of a new bike. He waited, while I went for the sag wagon (my car).
