Wind jacket came loose and wound in the rear wheel, trashing the RD (40'skid!).
Was able to shorten the chain, and single-speed the remaining 40 miles of the ride.
Another time got a stick in the RD 5 miles from pavement. Single speed again, but did not get the chain line right,
so the chain came loose under load- had to walk up the hills. Could have limped the hilly 10 paved miles but would have been late for a date, so made the call.
Third time stick in RD, bent hanger, but only lost a few gears, so completed the ride.
Even have pics:
