James T

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.

Ben R

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.

C Rowe

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!

What couriers do you use?

For UK shipments, we use DHL and Parcelforce. Both of these couriers have proven to be excellent; with superb first-attempt delivery rates and a simple system for the customer to re-schedule deliveries or select a safe place. For international orders we use DHL, Fedex and UPS.
