Which security chain?

Well I just locked up the bike. What a mission. It took ages this time but no doubt I’ll get faster with some practice. So some things to note.

If you fancy this chain and you measure the length you think you need add about 1/3 more because the chain doesn’t flex very much at all.

If you lock the front wheel you need to do some key hole surgery because the links are so thick they barely fit between the disc and the rim.

It doesn’t fit through the locking loops on an Oxford Stormex cover. It’s too large.

So still a great chain but there is a learning curve. And I really miss that link I destroyed in the name of research now.

This was the result of the Oxford Boss 12mm test. I wouldn’t use it to lock a fancy bicycle.

It’s not entirely surprising that an angle grinder can cut a 12mm chain in couple of minutes is it?

I wouldn’t lock a fancy bicycle up outside in london at all but I would be even less likely to cycle around with 20kg of chain in my rucksack - that’s about 3 times the weight of my fancy bicycle.

As Joby states in his video, it takes him only two minutes to cut the chain in ideal conditions, that being a vice secured to a work bench. I reckon it would take double the time if it was dangling from a bike touching the kerb.

I remember a documentary years ago on television, where a police officer that specialised in vehicle crime said, and I’m paraphrasing here, “If it’s a professional thief, and he wants a particular car/bike, then he will steal it”. So if I can get the thief to recognise that my bike has an Almax chain, and the other similar bike near mine has only a silly little Oxford or Datatool chain, then he’s less likely to invest the extra time and effort to steal my toy.

Tell us more TimR

I know nothing more am not a user only know of others who have purchased but not had to test them

There’s another 22mm chain on the market and it ain’t cheap to buy!!!
But I was more shocked by the stat of an average 500 motorcycles stolen a week in 2018!!

The latest Allmax series 6 is 25mm. It costs £500 with a Squire lock. The series 5 I have is hard enough to lift with each link weighing 1kg. The series 6 must be like a ground anchor.

Problem with that is that it gets to the point where they can’t cut the chain to steal the bike so they break in to your house to steal the keys instead!
Same thing happens with high end cars now.

It’s a pretty sad state of affairs and I’m sure we’ll soon have people having to keep their car and bike keys locked in a safe in the house if they want to buy nice things and not have them stolen.

The problem I see is carry a chain of that size and weight. Pretty much means you can’t carry anything else.

Any ideas how this was done?

When we cut it, it took ages and was a right mission. He cuts through in less than 2 minutes. I can’t seen any details on the cutting disc. Maybe it’s not an Almax series 5 and is a knockoff. The sleeve looks genuine though and the links look the right size. I can’t explain it otherwise.

Also if it’s this easy we are all screwed as even big chains are easily defeated.

Damn that was impressive.

Do the comments in this give you any idea?

Its what I’ve said all along about the Simpsons, misleading jokers from their earlier days of comparing 16 mm and 19 mm chains with 10 mm chains and now this. No chain is any match for the correct tool.

From the comments it looks like a 3mm disc is better than a 6mm for going through harden material.

Well I guess that using a 6 mm grinding disc means you’re having to remove twice as much metal than with a 3 mm cutting disc, which is going to require more time & energy for no gain.

It was a cutting disk. I just made a mistake and I didn’t want to reload upload the video. I should have re uploaded it really. Link to the disk is in the video description.

Loads of internet people have messaged me telling me how easy it is but no one wanted to actually prove it.

Still least we had a go. There was no research before we did it.

I should have a garage soon so then we can have a grind off and sensatonalose it for YouTube. Invite 5 challengers and see who is fastest. Do it for the views.

If I wanted through any chain quickly I’d use a gas axe. Do you need to know how to use one without killing yourself, yes, but it’s not difficult to learn. it’s probably beyond the reach of our aspiring footballers though.

If you fancy giving it a go I’ll sacrifice another series V link. I’ve a series VI link too. Could be a fun exercise.
