This chain cannot be cut by conventional bolt cutters. No more bikes stolen quietly while you’re asleep. This chain is widely considered to be one of the toughest, hardest security chains in the world. I guarantee you, this will be the best investment you have ever made for your bike.
Bolt cutters proof chain.
Case Hardened to 62 Rockwell (HRC)
This chain is considered to be one of the toughest security chains in the industry. Developed by company with centuries of experience in chain manufacturing for all industries including military.
This chain is extremely resistant against handheld cutting tools and bolt cutters. It features square profile additionally strengthening it, available in 10mm and 12mm cross section. Case hardened to 62 Rockwell (HRC) and core to 46 HRC. Thanks to softer core and much harder casing chain is not brittle making it also very resistant to sledge hammer attack.
Solid Hardened Steel Lock
Solid Hardened Steel lock. Designed with security in mind to be bolt cutters proof, featuring hard to pick brass lock core. Designed specifically for 10mm and 12mm chains for perfect tight fit to fully enclose shackle pin ensuring it can not be accessed with bolt cutters or other tools. Hardened just enough to be very difficult to cut but at the same time not to be brittle and be able to withstand sledge hammer attacks.
Weight vs Strength
One of the main aspects taken into account when we were developing this chain was it’s weight and portability. There are many very secure chains on the market right now but a lot of them are designed for safety and not portability. They are very thick, very heavy and mainly sit in your shed or driveway where you park your bike. They are simply way too heavy and bulky to take with you. Our chain is no bigger than any other standard chain lock, yet staying bolt cutters proof and providing excellent levels of security.
Every chain’s quality in the areas of bending and breaking is tested using a diamond stylus. Many samples were discarded ensuring only the best quality materials are used for each part of the chain lock. From chain itself, lock, to chain sleeve, making sure it does not fade or degrade when exposed to the elements.
