The new Squire SS100 padlock weighs in at a massive 4.3kg, and is claimed to be the strongest production padlock around...

NEED THE best protection for your bike at home or work? Then this total animal of a padlock has to be on your xmas list. Made in the UK by lock legends Squire, the new SS100 is 100mm wide – DOUBLE the size of the old SS50 - already a heroic lock in terms of protection. It's even bigger than the firm's SS65 and SS80 65mm and 80mm models, and a hugely serious bit of kit. Stainless Steel Cut Off Disc

The new padlock is a closed shackle design, with a boron steel shackle that's nearly-impossible to cut. Even scrotes with angle grinders will be looking elsewhere - this padlock will take a load of batteries and discs to cut through. Size matters here - the more metal in a lock, the longer it takes to cut through, and even modern high-powered cordless angle grinders start to give up. And if it starts to take 20-30 minutes to cut a lock, even the cheekiest baddy will start to get a bit twitchy.

The SS100 is the top lock in the new Squire Motolok range, and is paired with a 1.5m long, 22mm link hardened alloy chain, to make a seriously tough security package. It's too heavy to carry about on the bike, so will be a home or work job, but looks like just the job for keeping all but the most determined hoodlums at bay.

See the new lock at the NEC show - Squire is on Stand 3B44 in Hall 3, where they'll also be showing off a new prototype disc lock design, which aims to be 'Diamond' Sold Secure approved. That test includes an angle grinder resistance test, so will be tough for them to meet.
