Took my D7 for first time in over 2 months and when I was shifting down (after getting on a MUP with walkers and roller bladers), chain slipped and got stuck between highest gear and drop out. This occured without my tool bag with me. I would have needed screwdriver to pry the chain or adjustable wrench to loosen the wheel. The walk home would have been an easy 6 miles. I walked the bike for a mile heading home and then gave it one last attempt to remove the jammed chain. I tried pulling the chain up, down and sideways with brute force until it finally snapped out. I would still be walking home now if it did not work. Anyone have the chain jumped out of gear and stuck between cassette and dropout? Does anybody bring a tool bag equipped with basic tools when you ride? I usually do when my ride is beyond 10 miles and I didn't expect to be riding more than that but it happened after I had 21 miles.
