I have no worries about the security of my high value bikes with this chain coupled with the Torc ground anchor and Squire lock. Brilliant!

Beautifully made, with a high quality sleeve. I am using it with the round lock from the package deal. Great website to help guide you to the right choice. Actually the various tips are helpful in getting maximum security. Who knew this topic could be so interesting!

Speed and helpfulness of Pragmasis service can't be faulted.

Okay, the above setup is heavy to cart around, but there seems no avoiding that. By using an Anti-pinch Pin and a 13mm chain with a noose ring at one end, you can at least get away with a shorter chain. Two tips, though:

1. 13mm chain MAY not quite slip over the pin. Either order 2x links of 16mm chain (one slips through the first 13mm link and over the pin, the other stops the first link pulling right through), OR use a small sharpening stone in a drill to shave just a whisker off the inside of the first 13mm link in a small area.

2. Maybe order a long enough chain to go up and over the seat, so it's held off the ground (1.2m noose chain doesn't allow this, although it may still prove a good choice - not used it much yet).

Hope that helps.

I ordered the longer 2.5m chain to replace a shorter one due to acquiring more bicycles and the new chain is of the same high quality as the previous one. It works very well with the Torc ground anchor and Squire lock.

This is a great chain for bicycles. More practical than the 16mm as this will fit throw the wheel spokes a bit easier. This is the second one I have bought and the quality and service has been great from David. The keyed alike facility is excellent too and David was very helpful. Fully recommended.

The chain arrived promptly, looks exactly as advertised, and David was very helpful in giving a heads up about when to expect delivery, etc. Would highly recommend.

I'm impressed with both the chain and the service.

Got the 1.5m 13mm and it feels solid and secure, especially in combination with the round lock. Reasonable compromise between weight and portability. Feels much more secure than similar priced items from competitors.

David is the best! He offered a lot of advice on the different security options and was super helpful answering my (maybe a bit too many) questions.

Ordered on the Monday, delivered on the Tuesday. Great communication too. Chain looks solid. Recommended.

I have a pair of these.
I use them for additional security at home and as a carry chain for portability.
A good balance between protection and weight.

I have searched the web (eBay, utube, Google, etc.) and I could not find anything better (or equivalent) for cheaper!!
OTHER 16mm chains profess to be “uncroppable” but there are posts and videos that prove otherwise.
I only ever want to buy this kit once, and I hope it is never actually needed. The cost is cheap when compared to a loss of a valuable item, the damage caused, the trauma of the violation and the peace of mind of a purchase that will offset this risk.
I am really looking forward to your kit arriving (in a very nerdy way!)
Thank you so much for your help, technical advice and enthusiastic attitude.

Delivered on time, and perfect for protection of my 3 expensive bikes

Parcel arrived in The Netherlands in two days.
The 13mm chain 1,2m length is light enough to be carried in a pannier.
Except for the 13mm chain I also got the 16mm and two keyed alike D-locks. Various ways to use the D-locks, I think they provide more flexibility than padlocks.
Note that 16mm is quite heavy - to be used only for home parking.
All products seem very high quality.

Thanks to David, Steve and all there for helping me when I changed my mind with my order once I went to collect it.
Such helpful guidance in person and on the website means my bike is now firmly anchored to the floor with keyed alike padlocks for convenience.
Perfect all round - just wish all purchases could be this easy!

I purchased this lock together with an Abloy PL350 to function as a very solid secondary bicycle lock for my bike, which is kept in a Cyclehoop bike hangar in inner London. My primary lock is a Kryptonite NY M18 DLock, around the seat tube, rear wheel and crank and the protector chain complements this perfectly around the front wheel and down tube, so both locks can fit to a secure object. I think a d-lock and chain work well as a set up to mix up the two lock styles.

I do not think of this as a ‘portable security’ option, it is still very heavy so is part of a heavy duty ‘home security’ up. In the very rare occasions where I would lock up my bike whilst out and about I would choose to take my Dib series d-lock.

The manufacturing quality on the chain is clearly very high and Pragmasis’ customer service is always excellent. I sense that they take a good deal of pride in their products
[Pragmasis Comment: Yes, we do have a pride in our work. We care, a lot. We want to make good quality products in an environmentally and ethically sound way. It's the only way to behave if you want to build a sustainable business, in our opinion.]

Extremely fast delivery and a very good chain, Perfect!

I ordered a 16mm chain which proved to be way too big. After my wife chatted with David we've exchanged for a smaller chain on his advice. Nice to deal with a person rather than just be a number.

Ordered the 13mm chain with noose end to take a decent chain that I could transport around with me and upon receiving the chain I am well pleased with the product and service I received.

I asked myself "Which chain should I buy so I can sleep at night?"After reading reviews for chains from different companies on various sites, I knew I had to buy the Pragmasis Protector. I bought the 13mm chain for my very, very expensive Time Trial triathlon bike. The chain is incredibly solid and a very well-manufactured. It is obvious Pragmasis take security very seriously. I firstly read most of the information pages on their website to ensure I was buying the right sized chain for my bike. The information and videos were incredibly helpful. I did several test runs using rope around my frame and wheels to ensure I would choose the right chain length. I highly recommend this to everyone. To all the team at Pragmasis, a HUGE thank you. Amazing products can only come from amazing people. Peter :)

I was pretty sure after reading all the reviews before purchasing this chain I wouldn't be disappointed and I wasn't.
The chain is of excellent quality and service first class. I was kept informed every step of the way by David about my order and it arrived within 3 days.
Can't fault this company, would highly recommend

I have purchased 3 of these 13mm chains over the last few years and they have proven to be very durable, resistant to rust and corrosion (I keep them in situ outdoors year round). The size and weight of the chains act as a very effective deterrent to cycle thieves. Whilst many other bicycles have been stolen in both locations used, my Pragmasis chains have ensured that my bike is not an easy target. Great products at reasonable prices (not cheap - but a bike costs alot more to replace!)

Bought this following Bennetts reviews and the advice of Pragmasis' David, who is clearly very knowledgeable. He just asked "what bike is this for," and immediately knew what would work and what wouldn't. He advised on chain length, and lock and how to secure the bike with them. I am very pleased with the results. I am glad I followed his advice, the chain is big and heavy and a larger one wouldn't have fitted the application. I ended up buying also the RoundLock and the Torc, which are also excellent. I will review them separately.

Well priced, fast delivery and great quality chain. Good customer service too. Highly recommended.

Great product for securing bikes at home. Feels very secure Noose loop a really good option for one end

Great service

Great chain, feels heavy duty and like it will do the job. Even better customer service that gave good helpful advice and really quick delivery.

I have an expensive E-Bike which I use for couriering, so I have to constantly be locking it up. I found that a D-Lock isn't ideal, because somewhat often a place I'm delivering to or picking up from doesn't have a bike rack or suitable pole to lock to nearby.
Rather than either the very risky prospect of just immobilising the wheels, or having to waste time searching the nearby area, the 1.2m noose chain I bought opens up a much wider choice of things to lock to that a D lock either can't reach to or fit around.
I'm sure when I go on recreational trips with family and friends, the chain will also be used to secure multiple bikes at once.

The only downside I can see of this chain is the weight. (whilst I don't mind carrying it given I'm on an E-bike, I would were I not, and you have to be mindful when locking up to not bash anything), but, that's simply how physical security works, so I can't really take any points off for that. The longer link design would seem to save weight compared to the shorter links of mainstream competitors as well.

I have purchased several of Pragmasis' products in the last few years. I have a 19mm chain and ground anchor in my Garage & wanted a slightly lighter chain to use with my Motorhome in conjunction with D Lock. All their products are first class as is the service from David Briggs.I can't recommend them highly enough.

Superb quality engineering, well worth the money :-)

I ordered this chain by itself initially but later realised I'd need a padlock too. Got in contact with Pragmasis via email and David got back to me. He added a SS50CS padlock to my order and honoured the price they would charge for the Package deal!

Chain itself is great quality and the welding is fantastic, it's well protected by durable sleeving and just right as a carry chain for my motorcycle. 5 stars all round!

First class service from David fast post arrived on time Recommend this company.

Fast delivery and well packed
