    Great stuff, together with Burg-Wachter 100D it’s by a very wide margin the cheapest way to have a combination that achieves the bicycle diamond rating, anything else costs more than double.
    The chain is made of manganese steel, probably the best material when anything besides an angle grinder wouldn’t work, because it works harden like nothing else, of course it can still be cut, but it adds time. Also chains are harder to cut with an angle grinder because they flop around, unlike an u-lock.

    5.0 out of 5 stars This is rated bicycle diamond rated even though it doesn't say in the details

    If you love it, protect it…. !

    My only gripe is the massive 33% price drop just after i bought it… that’s not your concern though,, if you want a good chain and don’t mind the heavy weight… this one is the one you want. worth every penny !

    Don’t forget you need and equal standard padlock and an alarm I have a brake disc lock also, and an Airtag is a good idea also…. the chain alone will not stop pro theives!

    They are super chunky. Chain looks like it would be a nightmare for bike thieves to break. On the downside, very heavy th carry in a backpack. You can wrap them around the handlebars or frame.

    I checked many reviews for this type of chain, and came to the conclusion that this was an ideal choice. Good quality, weatherproof and looks good.
    Used together with a good quality security padlock.

    This looks really solid. It is really heavy. If you buy this good padlock is a must.

    Extremely heavy and thick chain made from a hardened material that is highly resistant to most attacks.

    Great for chaining up your bike as long as you’re ok with the added weight of having it in a backpack.

    Just keep in mind that at this durability it could be very dangerous to attempt to grind through.

    Remember that any chain is only going to be as strong as what you attach it to. Don’t bother buying this if you aren’t also prepared to buy a strong lock that is difficult to pick to go with it.

    Strength is a necessary and a good quality is expected
    Not Cheap but worth it for the Quality Square section chai

    A SUPERB VALUE PRODUCT, BUT THE DIAMETER OF THE LOCK’S HASP, YOU USE TO “JOIN” THE CHAIN, IS CRUCIAL. WON’T ALLOW ANY OF MY U-LOCKS, TO GO-THROUGH, BEYOND THE SLIGHTLY THINNER “U” ENDS, AND THAT DOES NOT AFFORD SPACE, TO ENGAGE THE CROSSBAR.
