Nope, not yet. Busted the seat tube clean off of the BB shell. Found a hardware store with 1/2" fiberglass backed packing tape. Strong stuff. Worked well for the last 10 miles home. Busted a rear der. cable. Just put a small stick in the derailleur to get it to stay in a middle cog. 3x1 for the rest of the commute. Busted ego once. Got blown off the bike( well blown over and then off the bike) over a snow bank, not a good time. Had to do some duck n cover once. Black wall clouds and tornados, nothing to fool with. Once saw me soaking wet and shivering. Under some garbage cans they will sometimes leave a clean one. Stripped off my base layer and wrung it out. Cut out neck and arm holes from the bag and put it on. Tucked it in as well. Put my wet windbreaker on over it, pedaled home. HTFU and YRMV.
