Went with 1.5meter long chain and noose end. No complaints. No regrets. Padlock is a little bit smaller than I expected (not a bad thing, just an observation). Happy I went with 11mm chain, the little bit of clearance near the padlock lets me wrap the chain around the frame of the bicycle in a way that it doesn't obstruct my legs and still keep it tight. Few zipties here and there to keep the noose loop horizontal under the frame, chain wrapped forwards then back around the frame, and again through the noose, with padlock hanging at the last link. Easy to unwind just as much chain as needed, and at least two frame "pipes" are always wrapped - there's no cutting the frame and riding off. Unless they literally cut the bike frame into pieces. Enough of the chain to reach even the thickest of poles, and can secure more than one bicycle for when I'm riding with my wife. Perfect! I don't quite feel the extra weight when riding (not after 2+ years of 12kilometers a day in all conditions), only when I have to pick up the bike or handle it when stationary. Even the protective chain sleeve was putting up fierce resistance when I needed to cut it to make space for interlocking chain link :-)

I bought the 2m chain for my 25yr old bicycle and the delivery only took 2 days to Germany. The chain has nice sleeve and the padlock is the lock with the smoothest operation I ever used.

The city this will get used in does not have many bicycle stands and often only a tree is left free, so I chose the 2m long 11mm chain. I can easily get one link through the frame of my brooks saddle (with springs, probably the most valuable part on the bicycle) while securing the bikes frame and back tire to something quite sturdy. The front tire just gets locked to the frame with the previously used D lock.

We needed a new lock to fit the Beefy Wall anchor to secure a second bike.
Measured the distance and bought the standard chain of 2m.
Ordered it on Wednesday evening and it was here 2 days later. It's heavy and the lock is very positive to use and lock. The cover for the chain is well made and secured, which makes it look very smart.

It works well into the beefy bridge as advised.
Using the two together - the U and chain, they fit into the bridge and do the job well - we hope!!

Great advice service and products from a brilliant company.
if we need more locks we will return to purchase from you

Having previously bought this chain and padlock for a mountain bike I needed something to secure a field gate. Bought it with the 1m chain and because the links go into each other I got it nice and snug between the gate and the post before securing the padlock. I had about 4 links to spare So that is perfect. Great service will use again.

2.5m chain does a fantastic job securing 1 or 2 bicycles in a South London front garden and has even seen off bolt croppers in its time. Used in combination with Abus U lock for added deterence.The SS50CS also works really well but likes some WD40 once in a while or can get sticky. Keyed alike service is brilliant and Pragmasis are very helpful. I prefer this to the 13mm chain which is heavy/care is required to thread thru wheels.

Impressed with the quality of this combination. At work I am supplied with some good quality locks and chains, but this is the first time I have used Pragmasis and I think I have the better option.

My second order to complement a 16 mm chain and ground anchor for bike security. Great product, matched keys across all locks and what amounts to personal service. Great experience and highly recommended.
