I live in Brooklyn and usually do not leave bikes outside "too" long . Right now I have a four sided krypto chain and one of their defective locks. Heres what im thinking of doing, should I get an American 707 lock (2-1/2" Wide, 1-1/8" Thick, 6 Pin, hardened steel) for the chain, and the krypto New York U-lock. Or just get the New York Fahgettaboudit chain and lock, and use nothing else. The reason Im leaning towards the american lock and New York U-lock is because id like to start doing some touring, and I feel like the u-lock is light and small enough to take with me and fairly secure for quick lock ups. (while in the city id be using both chain and u lock) However do u guys feel the New York Fahgettaboudit chain and lock is that much more secure the then other option, cause if so I might just go with that (I cant afford to buy both the new york chain and the u lock). Thanks guys, any other opinions u guys have on locks would also be greatly appreciated.
