Anyone carry a chain? A friend and I will be touring Europe for 3 months and he insists on bringing a Kryptonite chain and U-lock. I advised against it due to the weight but am I wrong? A 3ft. New York model weighs about 8 lbs plus the additional U lock. Is this too much weight for a lock to take touring? I was considering the 7" OnGuard Bulldog mini U-lock but then I wasn't sure what to do with the front wheel. Any advice?
