Man that sucks but you saved yourself a long walk with that clamp trick. I keep a couple of those tiny hose clamps in my bag too along with the usual zipties and a few chain links. Had a guy in our group snap a rear derailleur cable last year and we got him home with a short piece of cable and a cable crimp we scrounged up. Being the guy with a heavy bag beats standing on the side of the road waiting for a ride. I'd rather carry the extra weight than get stranded out there.
