Almax advise against anti-pinch pins
Discussion
Bear in mind that the infamous Almax video is there to make a marketing point about a product they sell.
Although the video shows the design of their chain to be far superior to other similar products, it does in no way guarantee any suitability for defense against other forms of attack. Therefore every case is different as are all garages, out-houses and houses.
You can only minimise the risk by performing an accurate security assessment on each aspect of the risk and not trying to adopt a "this product is the best on the market" approach, as a pro-thief will already have a method to circumnavigate it.
I might have mentioned it before but.. it's all about layers

I might have mentioned it before but.. it's all about layers
Questions you should ask yourself are:
- Is the bike visible from the outside world
- Are the public likely to know I keep my bike here
- Is the building able to withstand attack? i.e. a shed offer zero defence
- Is the bike just secured with a chain? = waste of time unless its actually chained through something,
- Does the bike have any kind of alarm and do you use it?
- What kind of anchor do you use? Can you fit the anchor to a wall where the fixings are not visible from outside?
- If a garage, do you have GOOD halogen security lights fitted at all access points? Villains hate being lit up!
- If using a "Henderson" style up and over door, are the frames and door reinforced and can you bolt it shut from the inside allowing side door access only?
- Side door is wood? Forget it, buy a fully steeled security door with 15 point locking - less that £200 with frame and can be fitted yourself in a few hours.
- Building alarm fitted? Does it actually let you know its gone off or do you come home to an empty garage with a lot of noise? No point having an alarm if it doesn't call or text your mobile.
- Budget problem? Buy dummy bell boxes from a local alarm company. They cost trade around £9 each so figure with their company sticker which adds authenticity and free advertising a cost of around £20 each supplied and fitted. Great deterrent and the boxes are real ones just not loaded. Look for cheap ADT yellow boxes on ebay, less that a tenner for the UK's biggest alarm co.
- When 'they' get past the door what other deterrents can you use? Smoke is relatively inexpensive if you do it yourself. Try stealing anything if you cannot see anything and can't breath.
- Got a dog? Best deterrent ever! "I live here" and "Beware of the dog" signs DO make a difference.
- Above all, every time you leave your bike think, "What's the easiest way to get that stolen?" This is exactly what a thief does when he clocks your pj.

As well as watching YouTube I also have two degrees in engineering and I'm currently doing my phd in computational aeroelasticity, which involves simulating shocks. I didn't want to jump straight on the "I'm more qualified so believe me" bandwagon, but since you've brought it up....Who will win?

My original point was simply based on the fact that on the forum you can only take things at face value; you have no idea of the experience or background of each poster (unless it is MTB), so if somebody can provide some sort of basis for their point, then clearly it lends credence to what they are saying. Clearly there's a point at which it becomes academic willy waving, but if it is a relevant factor in arriving at what you say, then surely it's worth mentioning. Now I simply don't know who to believe!

OK since everyone is banging on about their degrees, I've got a honours engineering degree, a master of engineering degree a physics degree so 3 x degrees all up and I'm chartered engineer. I design oil platforms (made of steel) for a living. I also have a great sex life, can fly, scuba dive and am taking 6 months off on holiday next year Who will win?
Anyway, there are many types of steel. The explaination that Almax have provided makes sense to me. They say the outside of the chain has been hardened as are most chains. The properties of steel This increases the yield strength of the chain, however it means it may also be subject to brittle failure more easily than unworked steel.
The inside remains softer but ductile, that is it will bend before it will break.

Almax state that their chains are case hardened. Explanation here.

Cheap thin chains are not case hardened, they are through hardened.

Yeah, fair one. I thought you were having mcuh more of a dig than you actually were. Sorry I bit your head off a bit. Now I simply don't know who to believe!

The video's really interesting btw, well worth a watch.

So is there any shockwaves or sound of some sort they could contribute to the chain breaking, on any chain?Anyway, there are many types of steel.

I think it unlikely shock waves would come into it, however the precise mechanism of brittle failure at a microscopic level is a highly obtuse subject. So obtuse that even somebody with 3 x degrees who does steel design, it is outside the scope of my immediate knowledge. However, the mechanics of a slowly applied stress are different to a rapidly applied stress. I think if cutting a chain, the point at which the jaws close would be a rapidly applied stress, although still not related to a shock wave. (You were rubbish at sex by the way but now I know you've got degrees coming out of your arse it explains everything!)
Sorry about the duff sex, I'm sure they sold me fake Viagra last time.

No problem. I was genuinely just interested as to the reasoning behind each viewpoint. With my engineering background extending to Maths and Phyics GCSEs (
) I didn't have a clue as to the reasoning behind each answer. I have seen that video before, interesting stuff.
