View Full Version : Cut Resistance: Kryptonite Chain vs. U Lock?

~ Hello ~

Although I realize that all locks can be eventually defeated given enough time and the proper tools, I was wondering if anyone actually knows which is more resistant to attacks - A Kryptonite NY chain or U lock?

The chain and U shackle both appear to be about the same thickness, so I imaging they would be about the same in cut resistance.

I've read about leverage attacks, and I would imagine also that a chain might be better suited against such an attempt - on the other hand, a well placed short U lock like the Mini Evo does not allow for the insertion of such devices.

Yes, I am paranoid, thanks for your concern. :rolleyes:

I have the NY Chain lock or similar, it wasn't made by the Kryptonite bunch, and my padlock that goes with it is incased and hides the loop so it can't be cut with bolt cutters. I swear by my chain, and wear it around my waist while riding. I like the chain better because sometimes a U Lock won't work, and the chain is more versatile, and you can tighten it up and wrap it around several times, so the person attempting to steal the bike can't get the leverage they want.

I have had several bikes stolen over the years, but none in the past three sinse i got the NY Chain. Don't leave home without it.

ya good point - a chain does allow locking to a wider variety of objects...

Well I feel much better about the Krypto chain - I have an older, 4 sided one and today a friend and I shortened it by a few links because it really did not need to be so long. It took us a good 20+ minutes with a heavy duty angle grinder plugged into the wall.

That said, I'm actually considering using it as a secondary lock and adding a Krypto New York Faghettaboudit U lock just because the shackle is like 4mm thicker.

Here's a shot of it next to a mini Evo (pic taken from another forum)- the thing is monstrous, and probably weighs about as much as my bike.

Of course, I may end up having to tow the lock(s) around in my bike trailer...

The way I see it, you spend big $$$ getting a really nice lightweight bicycle then you have spend more money buying a expensive/heavy lock to keep it yours.

If you had a secure place to store the lock when you were off the bike, that would be a improvement, but lugging it around on your lightweight bicycle defeats the purpose.

Harkens back to the old (tongue in cheek) adage:

All Bikes Weigh 50 Pounds

30 pound bikes require a 20 pound lock.
40 pound bikes require a 10 pound lock.
50 pound bikes don't need a lock!

One more thing I've recently learned here - The Krypto Fahgettaboudit can get around my seat tube, rear wheel, and a bike rack pole ONLY if I'm using it with my road bike. It is too small to do this with my mountain bike (Kona Blast). In order to lock up both the rear wheel and frame to a standard bike rack I can only get it through ONE chain stay. Kinda don't like that.

You don't need to lock the frame if you're locking the rear wheel. Just lock the rear wheel through the rear triangle and both wheel and frame are secure. There's no way of taking the bike unless the thief actually cuts through the wheel and tire where the lock is. Otherwise, you would have to either pass the wheel or the rack through the rear triangle, which is not going to happen.
