For years had relied on 13mm chain through front wheel and around exhaust downpipe!
Finally got my act together and concreted in a ground anchor which combined with this very beefy chain and lock gives much greater peace of mind.
Also has a nice quality cover which works well when feeding the chain through a smallish gap around the back of the engine.

High quality chain and the round lock inspires confidence. David @Pragmasis went above and beyond to ensure I purchased the right kit. Excellent customer experience and very happy with the product. Wouldn't hesitate to recommend to others.

Was impressed with the quality off chain and round lock. Bennett’s review help a lot on choice..Round lock was really good…added benefitted can be used as disc lock...so purchased another for the best chain..wish I had found this deal package before …I would off saved pounds…communication with Pragmasis …bang on..thank you.

This package deal arrived the following day mightily impressed straight away. All keys cut the same as requested and work on both locks. Female locking body for use on the chain works as described in video. Standard female locking body works as disc lock if required on second lock but take note of sizes as it may not go through or if the aperture is too big it will simply fall out. 2 metre chain nicely protected for threading through where required. And at this length and this section of chain you will need that as it is heavy, it is not unwieldy but you need to be mindful when locking up your pride and joy. A Very satisfied customer.

A great product and very secure. The matched keys is a nice touch.
Great service from order to delivery, They queried my mistake on the order to make sure I got exactly what I needed.

Went back n forth on chain size and lenghts, bought two, this 19 mm and round lock and the 16 with dib lock. This is heavy, well protected quality chain and frankly glad I didn't go up to the 22 cos I don't think it would have fitted round the bike. Paired up with the torx maxic, I think it will def live up to its protector name. Next day parcel force delivery just adds to the great customer service. Thanks pragmasis very happy.

I ordered this chain to lockup my motorbike at my rented home to the removable Double Doofer Pragmasis anchor. It is very well made, heavy and extremely solid. Even the welding looks the best I've seen. I would definitely recommend. I have even ordered a 13mm Pragmasis chain for portable use.

Excellent high security chain and lock. Works great with the double doofer ground anchor. Buy with confidence.

Bought this 19mm chain and roundlock combo along with the torc maxi ground anchor,and I'm very happy with all three items.

Opted for the noose-ended chain, which gives a little more flexibility in how it is used, but this is generally the permanent, overnight fixing point for one large cargotrike stored in our front garden. The noose end allows us on occasion to lock all the familys bikes with the 19mm chain, aswell as running several smaller bike locks through the anchor point aswell.

I have no hesitation in recommending the quality of these products. They are probably slightly more 'overkill' than my needs warrant (16mm would have sufficed),but i have no doubt and potential thief even glancing at this setup will realise it would be significantly easier to just cut the bike in half than remove either the anchor or chain.

Very happy with the purhase of Pragmasis 19mm chain and Roundlock.
All their products come top of the Bennetts attack testing and this product is no exception.
Have spent a lot of money on many of their security products but consider them to be worth every penny.
Quick delivery as always
Thanks

This package offers excellent security for the price and when combined with an anchor (Oxford Anchor) provides peace of mind. 1.2m is a little tight but helps to keep the chain off the ground

Serious stuff this!!

Great product.
Great price.
Great next day delivery.
Outstanding. Thanks

Wow ,you don't get service like this in UK, everything was on time ,all parts correct,and super quality chain and locks.
Will definitely be buying a 13 mm chain
For mobile locking of bike.
Great communication from seller , buy with confidence.
Well happy .
Tanks
[Pragmasis Comment: Err, we _are_ in the UK :-) Glad you're pleased and thanks for the feedback.]

Fantastic security and fantastic customer service. The 19mm is easier to handle than the 22mm and works fantastically well with the roundlock. I have it secured through a Double Doofer ground anchor and it fits like a glove. Top motorcycle security and very good value for money.

Highly recommended.

Couldn't be happier with the products and service. If I need anything else this company will be my first call. Thank you.

I'm impressed with the quality of the product (19mm chain & roundlock) and impressed with the service. This is how business should be done. Thanks Pragmasis

Fantastic product could moor a ship.

My last bike got stolen due to myself cutting corners.
This one will be going nowhere,do it right first time and sleep at night.
5 star service from start to finish.
Many thanks one happy customer

Excellent product as I have come to expect from Pragmasis. Service and support also prompt and friendly. I highly recommend. Bike now has 19mm chain with pinch pin and ground anchor :-) Thanks Pragmasis, you emptied my bank but you get what you pay for :-)

Top quality chain an absolute beast wrapped in a good quality sleeve with a round lock and a torc ground anchor brilliant communication with the staff came well packaged tracked with parcel force and a day earlier thank you very much.

Forget your chains you can pick in up in certain retail stores. This is a really big and heavy chain and having researched through online videos, both this and the Roundlock are a perfect deterrent for locking your bike at home.

Obviously it goes without saying, but this is a heavy duty chain, with emphasis on the heavy, so not one to be taking out on the bike. In situ in the garage it's an excellent deterrent, but one that'll likely only fit through your wheel and not the swing-arm for instance, simply due to the size. The canvas sheath does a great job of protecting the wheels etc, although very quickly picks up any oil/muck from the chain if it comes into contact with it.

The Roundlock is the real surprise star of the show though, as it's able to pull double duty as a disk lock when not being used to secure the chain. The package also includes the 'smaller' original locking piece as well as the larger optional part required for the 19mm chain.

After researching options offered on the web to secure my motorcycle in the garage, bought a 19mm chain, 2 roundlocks and a Double Doofer ground anchor . All were dispatched immediately. Service second to none as is quality of the products. The roundlocks are exceptional also acting as disc locks. So impressed I later ordered the 13mm chain as portable security. Definitely recommend.

I've owned this item a few weeks and being for a new bike I've used it everyday. It fits snugly through the front wheel of my F800R, it also fits through my bike's gap behind the cylinders without issue.
Delivery was great, communication from the supplier was on another level! It's strange how a personal email from an online company makes you feel a valued customer but it does and will influence my decision next time I need to buy a chain. Would recommend without hesitation.

Just purchased a high value motorbike which is kept inside a secure garage and wanted to upgrade my existing lock and chain which I use with an underground anchor (a “U” shaped tube that I concreted under the garage floor), as it’s a few years old and nowhere near todays standards. After numerous YouTube videos and forum reviews comparing various security options, I opted for the 1.5m 19mm version, and I’m actually really glad I didn’t go bigger! I wanted something oversize to the point that a potential thief would see it and just not bother, so was originally looking at either a 22mm or 25mm chain combination (I don’t care about the weight as it won’t be moved), but after measuring the diameter of the ground anchor (70mm) the 19mm was the biggest diameter I go for, and even then, it’s an extremely tight fit! There’s no way I could have used a bigger chain. That aside, the measurement that actually caught me out, was the distance between the front brake rotor and the wheel rim! The chain must be wiggled to fit through the front wheel due to the gap being very tight and I had completely overlooked it! Had the chain been any bigger, not only would it not have fitted through the floor, but also not through my bike wheel! I could have turned the bike around so the rear wheel was secured by the ground anchor, but I reverse my bike in when parking, so it’s easier to get out, and this would have been a pain. The quality of the chain is superb and the canvas protector does a great job at protecting my wheel from any accidental scratches. For anyone considering this for a motorbike, make sure you get the measurements of all gaps the chain needs to go through to make sure you don’t get caught out! But it’s a really chunky bit of kit, well priced and well worth the money and peace of mind!

Very good service and best price on the net. Very impressed with both the delivery speed and quality for the lock and chain, definitely will last my lifetime and a big deterrent for onstreet parking/long term parking. Key is a bit of a fiddle to get into he lock but evidently as a counter to lock picking.

I've had this a while now and felt that it is long enough to give a proper rating of this combo as some locks and chains can end up being fidgety and unreliable. Not these beauties. The round locks themselves are fantastic and handy that they make a good disc lock to take out and about with you. They'd be a nightmare to try and overcome. These, coupled with the 19mm chain give me peace of mind when the bike is locked away. The 19mm is a good size that it is still manageable with certain anchors and being able to fit it through sections of the bike for a more secure fitment.
Brilliant kit that I have reccomended to all.

The 19mm chain and roundlock are perfect. Much bigger and heavier than I thought, which will definitely put off any theives. I had to watch the YouTube video to understand how to put the lock on, but once I got the hang of it, it's very simple to use and so secure.
I had initially ordered the 16mm, but I was informed that it was out of stock. As my motorbike was being delivered the same week, David helped me choose an alternative and ensured it would arrive quickly. Extremely happy with the support received. Would recommend !

Heavy thick quality chain & lock. Kept up to date with delivery which was really quick. Recommended & would purchase from again.

Bought this after watching Youtube videos of how quickly inferior chains and locks can be broken into. When it arrived I actually laughed out loud at how heavy the chain is. It's not messing around, the lock seems smart and sits very flush to the chain making leverage attacks harder.
