Locks that work

I don't recommend the Squire Urban Paramount and here is why:

heh, I wonder if it could be repaired with gaffer tape ._.

There's a review of sorts of the Knog Strongman here:- http://cars-supercars.blogspot.co.uk/2012/05/bike-lock-comparison-by-men-journal.html 1:45 to cut through with a battery powered angle grinder

Nice how they don't bother to mention how long it took to break through the Fahg Mini or Abus 54 so we can compare it...

A Bikeradar review of it is online, only a few days old... "The Strongman stood up to the first of our usual lock tests, a five-minute attack with standard tools, and in the subsequent power tool test the shackle took just over 30 seconds to cut through, and that was after a minute or so of cutting away the silicone cover. It all adds up to an impressive little lock." Doesn't seem too bad to me. I'm guessing it could be cut with 1000mm bolt cutters just about? Seems like it should at least make it onto the secondary locks thread.

someone here states that a Kryptonite new york only lasted just over a minute against a grinder and that's a thicker lock.

While they failed to crop it, they were only using 2' bolt cutters, so that was not much of a test at-all - in fact only 1 lock they tested cropped, and that was a TiGr.

But a round shackle has a smaller cross sectional area than a square one. So 13mm square Abus is like 16mm Kryptonite. I don't see TiGr in either of the links you posted :S
