The Motorcycle Gold test on the Protector 13mm chain (July 2009) resulted in a brand new set of Irwin Record 42" bolt croppers having their straps being bent such that the jaws no longer line up and the jaws themselves were also wrecked. This was a very determined attack but the chain did fail in the end. We are unable to crop the 13mm chain as it needs someone with a lot more weight to do it. However, even the very best sub-16mm chains are marginal at the new Motorcycle Gold standard as that test is performed by big guys. Whether thieves are all big enough, regularly so determined and frequently wrecking 'their' croppers is another matter, but we still recommend that you use a minimum of a 16mm chain if you are protecting any item where that type of attack is common. Much better to have security that gives you confidence rather than something where the thief may well get lucky.

Magazine Awards

What Mountain Bike "Beat the Thieves": Protector 13mm and Squire SS50CS: WINNER! 5/5 "Massively strong against any tools, but its weight means it's for home use only. After five minutes almost every tool we threw at it was well worn but the 2m chain withstood them all. The chain also beat our 5 minute power tool attack." What Mountain Bike September 2011, p69

Cycling Plus Magazine "Toughest Security Test Ever": Our Protector chains and Torc ground anchor are awarded Best Buys and Editor's Choice. "After five minutes almost every tool we threw at the Protector was well worn but the chain withstood them all. Massively strong. 10 out of 10 Best Buy" [Protector 13mm]; "At less than £100 this stands head and shoulders above its competitors; at under £50 it's simply astonishingly good value. Hands down the best chain you can buy for less than £50. 10 out of 10 Best Buy" [Protector 11mm, 1.2m, M50D lock] Cycling Plus, October 2010, p74

The Protector 11mm chain with M50D lock was described as "Made of the same tough stuff, this is the best chain you can buy for under £50." (WhatMTB November 2009, p92)
