"First stage attacks didn't touch the chain or the lock. Our mechanical attacks did get through eventually but had to make a lot of noise for some time in order to do so."
"The Protector range from Pragmasis is perhaps the ultimate bicycle chain lock. The 16 mm links are formed from hardened boron steel and are impossible to bolt crop."
"The shackle on this (the DIB D-Lock) is nice and beefy, with a 16mm diameter, made of a very well hardened S2 tool steel. This is a product that I would consider using."
"The RoundLock is outstanding, offering excellent security in a small, light package, as well as adding even more value by doubling as a disc lock."
"The 16mm hardened steel shackle of the DIB D lock is impossible to crop by hand with standard manual croppers and can even withstand the largest 42-inch Irwin Record bolt croppers."

Great products
Thanks for some great products. Your kit protected my bikes perfectly during a burglary a few years ago and it’s still going (extremely) strong.

Still going strong
I bought from you once and only needed to buy once in 2016, but suffice to say that the 19mm bespoke length chain, and ground anchor installed according to Pragmasis instructions are still going strong, keeping my bike safe just off the street in Brixton, London.
Mr B
Wholly impressed
I would like to say I am wholly impressed with the ground anchors, chains and padlocks that I have purchased over the past few years and will always recommend you when the opportunity arises.

Torc Ground Anchor
Excellent quality piece of kit. Our second anchor to date. Exceptional service. Nice to see a British company up there supplying quality goods and customer service
Steve
Top class service
This is a serious chain! I certainly feel more comfortable that my bikes are well secured. Very pleased with the service too. I phoned then placed an online order and my chain arrived the next day. Excellent product and 1st class service. Thank you!
