Well it may not actually be indestructible but unless you are carrying a small workshop with you and have plenty of time, I suspect this is as good as. I have a 2m length coupled with a Squires 50CS padlock and a ground anchor and use it to secure a number of bikes in the garage. Service was great and they matched the keys to an existing Squire lock I had to make life easier. Recommended.

Really pleased. Using this to lock my 2 eBikes to our Motor home. It is also just about manageable to takeout shopping etc (they are e-bikes after all:-) It is quite heavy but you can't have it all ways.

I purchased the 2m 13mm chain with noose ending. The noose ending is very convenient, and greatly increases the versatility of the chain. I am using it to secure two bicycles, attached at one end to a wall mounted anchor, and using the Squire SS50CS lock at the other end.

The chain seems VERY robust. To be honest, the weakest link by far is my anchor, so I don't think any thief would bother with this chain. They would almost definitely damage the bicycles beyond sale-ability if they did. I also loop the chain around the wheel + main triangles so that, even if they remove the anchor they would still have great inconvenience moving the bikes.

Obviously I cannot accurately attest to the full security of this device, because no one has tried breaking it yet!

I would emphasize an obvious piece of advice - make sure all the various links in your security system are well-matched, otherwise you may be wasting your money on the top chain. e.g. consider the 11mm chain for added portability.

Overall very happy.

Bought this lock in 2-metre flavour with a noose end to slow down any scum who take a fancy to my mountain bikes.

I have it through am Oxford ground anchor on the wall, then through 3 bikes.

Seems very well made and the red cover is really nice quality.

Can't comment on how easy it is to break and hopefully I never will, but it's certainly a deterrent I'd say.

I ordered this chain on Tuesday, and it arrived on Thursday at my address in Belgium.

I don't think I've ever ordered anything in the UK that shipped faster than that.

The chain itself is nice and heavy, and the welds are really nice! Even though the site states that the noose is handmade and may look a bit different, I couldn't tell the difference and it's all top notch.

This chain is sure to scare the buggers away!

Just purchased the 13mm chain.
Very good quality craftsmanship, nice welding and protector sleeve.Easy to use Squire lock.
Was amazed at the weight, had to spend some time to find "holes" in the motorcycle frame to be able to fit. Ended up fitting trough swing arm on one of the motorcycles and around the rear shock on the other, than routed town to ground anchor. I cannot imagine how people can handle the 16-22mm chains? This one 13mm seems strong enough to deter any thief. Although I have alarmed garage.

Has protected my bike for years and I have confidence in it. Have bought 3 through the years, this is the only brand i trust.

Bought this chain in a package deal with the Torc ground anchor. Great bit of kit. The kind of stuff you can imagine a thief looks at and just walks away. 5 stars and worth every penny.

The 13mm noose chain is probably the best bike lock in the market. Better than any German bike lock from Abus. A bit to heavy for transport but perfect for stationary purposes.

Today I received the 13mm chain together with the double doofer. The quality is very impressive and convincing. The ABUS stuff looks like toys compared to these products.
Additionally excellent customer service. They informed me about a slight delay of my order which was not really worth to mention. Quick delivery, anyway. Perfect!

Having recently had a bike stolen whilst chained up with a chain marketed as a motorbike chain which was cropped like a hot knife through butter I decided to do some research into my options. As a day to day chain for my mountain bike this is brilliant it is a huge bit of kit which i can very easily imagine bike theives would contemplate taking a hack saw to the bike shelter rather than try to crop this.

It is a very heavy chain to carry around every day but to keep your pride a joy safe it is worth it.

Amazing customer service too which made me convinced i had gone for the right option. I will be recommending these chains and this company to my MTB friends.

I have 5 bicycles whose value amounts to around £6k, I've been totally worrying about their security for ages until I came across these products. So, I've just installed the Torc II ground anchor into my garage along with the Protector 13mm noose chain & Squire padlock. Really impressive,well made, solid kit!!
Highly recommend

This is a very tough chain which seems of high quality. The covering protects the frame and is of adequate length to wrap around my three most valuable bikes.
It was bought in conjunction with the Torc ground anchor and a Squire SS50CS Stronghold Padlock, and has been installed in my garage which has a flimsy door. Total cost was £175 and should deter almost all potential burglars. Compare it with £500/annum for bike insurance and it's a no brainer.

Excellent service and very good communication via email.
The chain is very solid and quite a lot lighter of the 16 mm one. A good compromise to be brought around on your bike

A well made chain and lock, very reassuring knowing I have this fitted. Top service from Security For Bikes too.

This is the second time I've ordered a 13mm chain and SS50CS padlock. I've had the same set up protecting my mountain bikes for the last couple of years, with a lot of reassurance provided by them. A new bike meant some additional security was required.

The service from Pragmasis has been exceptional. I asked for a 'keyed alike' lock to save confusion. David kept me up to date throughout the ordering process, explaining timescales, etc. The chain and lock arrived quicker than expected but an early email notification meant I could ensure someone was home to accept the delivery.

Absolutely spot on service and a product that I feel I can trust to do its job. So much so that I recommend Pragmasis whenever anyone asks me about bike security.

I ordered 1,2 meter 13mm chain with a noose chain at the end for my bicycle. 1.2 meter is enough for most uses and the noose adds a lot of versatility. Very well made, I'm a happy customer.

Ordered the 13mm 1.5m chain to carry in my motorcycle tail pack. Fantastic chain, received the next morning. Excellent thanks.

Having just retired we decided to purchase 2 new Electric Bikes. These will be kept in an outbuilding on our property. We purchased a 13mm protector chain which is fastened with an anchor to a brick wall, the other end connected to a good quality Abus D lock. The chain is top quality with a sturdy sleeve. It would probably be too heavy to carry on a bike but as it is a permanent fixture weight doesn't matter. Although the chain is fairly expensive (as are the Abus D locks)in security you only get what you pay for. Cheap products are a false economy. Very satisfied customer.

I was after a chain and padlock to secure my motorcycle to an Oxford Rota Force ground anchor. Unfortunately the loop in that anchor won't accept a 16mm chain so I opted for the 13mm chain. The added advantage of this is that is fits through the hole in the rear axle,of my R1200GS. I feel this is a better option than threading through the frame as well. I bought a package with the Squire padlock as well - and a great padlock it is. I wish I had checked this company out beforehand then Inwoikd also have bought their Torc ground anchor - bugger! I purchased a 2m chain and would definitely recommend getting a slightly longer chain than you think you need to give more flexibility. The service from Pragmasis was fantastic - personal emails to advise of despatch and ordering. I didn't call them, but I am sure they would offer the right advice to ensure you choose the right solution for your needs.

Just finished securing my two bicycles with the 13mm protector chain. Its massive. A 1,5m chain was enough to lock the bikes to a ground anchor. I thought of the 16mm version, but that might have been to heavy for the bicycles (something to consider - spokes and carbon fibre parts).
Excellent customer service, fast shipping.

I bought 2 meters of this and use an Abloy 626 padlock, although a bit heavy to carry around I find it only a slight inconvenience compared to losing my pride and joy, this setup will stop all but the most well equipped determined theif. Excellent, speedy service too!

Its just as described in the video and supplied by a very helpful company which delivered it very promptly. I just hope it never has to be tested but expect it to stand up to most assaults. All round good value.

I purchased the 13mm chain and Roundlock package deal to protect my bicycles in the garage. I received excellent advice on the appropriate size to go for, and once i'd placed the order I had it in my hands well within 24hrs so the service was absolutely spot on. The chain itself is a beast, looks and feels incredibly secure when used in conjunction with a wall anchor, and i'm sleeping much better since installing it. I'd say someone is going to have to make an almighty effort to defeat this. Recommended!!

This is an excellent heavy duty chain and lock. I feel confident that it will protect my bike. At the very worst, it will slow down any thief.
David gave me excellent advice, changed the chain after I'd ordered the wrong one and provided a number of security tips.

Now got 4 metres of this bad boy holding onto the ever growing cycle fleet as a secondary level of security. If the scumbags manage to get through this after level 1 security, I will give them the bikes myself!

After being so impressed with the 1st chain I ordered I purchased this one as extra security. Super fast delivery and excellent quality

Great value for money and excellent service

I am really impressed with the quality of the product and the efficiency of the company. Fantastic!

I opted for the (still quite hefty!) 13mm chain to carry it on my motorcycle. All my research indicated that Pragmasis was the best supplier for effective protection and good value. Delivery was next working day. Excellent service & highly recommended.
