Locks that work

they are better i give you that, but you wont see me using them.
They are much easier to crop, even the 16mm ones, which are inconceivably heavy metal monsters to carry around.

Yes Dylan, but the fact that YOU won't use them, means nothing really.

16mm chains easier cropped than maybe 13mm U-locks for example? Oh yeah? Link please.

Also, didn't you read this, post 43, of this thread? It categorically states that these chains are so heavy, that they are best left in the place where someone means to lock up their bike. Carrying such a chain around is positively NOT recommended.
