The KryptoLok Combo U-lock is like a tough nut: you just can't crack it. Thanks to the 13mm hardened Performance steel shackle that resists cutting and leverage attacks, you get peace of mind while you run into the grocery store or lock up outside the coffee shop. A built-in four-digit resettable combination gives you easy unlocking and locking capabilities--no keys necessary! You can also take advantage of the Transit Flex Frame bracket for plenty of convenient mounting options. The KryptoLok Combo is 4 x 8-inches and has an anti-theft protection offer of $1,250.
Never forget or bother with keys again. Fast to deploy and lock and includes a very varsatile mount to carry this on most any bike. Plus it is a bar type U-Lock that is resistant to cutting albeit not a ultra strong model. Never lost a bike using this for over 10 years in Vancouver Can.
Bottom LineYes, I would recommend this to a friend
