ONGUARD Mastiff 8019 Bike Chain Lock & Shackle U-Lock (Sold Secure Gold)

Product Information

Instead of taking the maximum profit route, they provide high-quality, durable products that last longer than other brands whilst offering a great user experience. A step up would be the Kryptonite New York chains. They can be cropped too but with much more difficulty. The Superbright version also has the added benefit of keeping you visible at night, so is a great option for commuters. As I briefly covered earlier in this ABUS CityChain 1060 review, the keyhole of this chain is guarded by an automatic keyhole cover. If you only use it to secure your frame (tightly wrapped around your top tube), you can keep the chain shorter (and lighter). And even more significantly: it will be further from the ground so it will be much harder for a thief to crop it.

They both come in a variety of lengths. But I recommend you go for the shorter chains and wrap them tightly around your top tube rather than using longer chains to secure your wheels as well. Firstly, because they're relatively long and flexible, you can secure your bike to a wider range of objects. But these chains certainly can be cut by bolt cutters if the thief knows what they’re doing and can get the chain in a favorable position.So if you're high risk, which should it be: Gold or Diamond? Well the truth is: it's a bit complicated at the moment!

Links with diameters less than 10 mm can be cut relatively easily with medium sized bolt cutters if the thief can get the chain in a good position. The 8020 weighs 6.28 lb (2.85 kg). That’s the equivalent of 7.5 cans of coke. So while it’s perfectly possible to carry this chain around every day, it is very heavy. And you’re really going to notice that weight whether you sling it over your shoulders or wrap it round your frame! Is the OnGuard 8020 Mastiff easy to use? Even though the Fahgettaboudit uses high-quality corrosion-resistant metals, I’d recommend cleaning & lubricating it every month. Secondly, because you can wrap them around your seat post or top bar, they can be easier to transport. This way even a 7 mm chain might be strong enough to protect your bike as it would be so far from the ground it would very difficult to crop.The ABUS Granit CityChain X-Plus 1060 has once again reminded me of the quality that ABUS provide for their customers.

The Mastiff comes with a lifetime warranty which covers you from manufacturing & workmanship defects.This sheath absorbs water if left exposed to the elements, so if you’re transporting the chain in your bag, you may want to carry a plastic bag in bad weather. ABUS offer their customers a 24-month warranty on all of their products, including the ABUS Granit CityChain X-Plus 1060. A 99% waste diversion rate within their factories is one accolade I was impressed by, alongside a 50% share of renewable energy in their energy mix. You'll have to come with a different way to protect your wheels, but there's load of options and at least your bike will be safe!
