Wow. You're sure about this Retem?

when it was first introduced in the hardware world it was called campbell security chain you need a diamond cutoff wheel to cut the stuff and it is expensive other companies by from campbell manufacturing and brand it their own

You really sure?

so far it's U lock with key (not the barrel kind) or a small lock so less room for theifs to steal it and the forgetaboutit chain

and the winning company so far is kryptonite

one question - what kind of lock do u guys use for those humongous chains? master?

well what I saw althought impressive was that quite a few of those chains didn't have a hexagonal link cross section besides I use a peice of grade 85 to chain for my bike it broke a pair of 36" bolt cutters and damaged a hydrolic cutter before It broke

I also use a u-lock as well

and yes campbell security chain comes in precut lengths because it is very dificult to cut

****, that video really shouldn't be on the net, for God's sake. Damn.

Yes, barrel-type keyways have a tendency to stick after a while. Lube them. Like oiling your chain.

It's possible that you live in a place where a cable suffices. However, based on your apparent experience with breaking locks, I'm surprised that you would make such a comment in an international arena with the majority of its users living in urban areas.

In most urban areas, a cable lock is only acceptable as a supplementary lock, not as your only lock. If you U-lock or chain to a secure location, then you have a much better chance of most of your bike still being there when you get back.

The bike with only a cable lock will be the first targeted by a potential theif.

Where you park is important to how well you lock your bike. When I park in my house, or in my office, I won't use a lock. When I park outside the coffee shop where I can still see my bike, I'll just use the cable. Anything where I won't be in sight of the bike and it gets a chain or a U-lock.

You must either be really naive, or you just ride to the coffee shop...

no he's just from gainesville and it's a small town that you don't have to worry about much as far as bike theft goes.

I was working at a shop when that thing happened and we tried very hard to open one up with a pen but never were able to so I think that myth is "busted" (or maybe we weren't good as thieves)

Kryptonite always has the the best lock IMHO

you really think kryptonite would've done a recall on all of those locks if it was just a myth?!

dude I have done it I think I bailed about five people at college out last semester lost keys campus police trying at it with an 18" bolt cutter you knpw the scenario

IIRC, not all the tubular lock ones were vulnerable, but they recalled all of them anyways. I can't open up my old New York U-Lock with a pen, but I won't chance it in NYC. I do in Boston or Hartford though.

just carry your bike with you

this video makes it look easy but there's a couple of things to think about: attitude and risk. If you look like you know what you are doing, people won't question it. i'm not saying that people always will, but a confident attitude and posturing means a lot. if you are a sketchy looking crackhead filing away at a bike chain and constantly looking over your shoulder, you are gonna arouse a lot more suspicion then someone who very well could be a city or building employee or something.

basically they've done a proof of concept, but unless bike theives all start getting balls of steel, you won't see any theif hacksawing a lock away for 8 minutes in broad daylight. well, you probably wont see many. a real thief has to worry about a few things that these guys dont: a) cops, security guards, and the like b) that the owner is gonna come back anytime now, and c) the off chance some bystander *might* intervene, or even if they dont, they might still be around when the owner comes back and starts yelling about his stolen bike. by nature theives are gonna go for the low hanging fruit most of the time.

Don't lube bike barrel locks with WD40! Eventually your lock will jam because WD attracts dirt. Powdered graphite is what you want. A good locksmith will have it.
