Chain

Magnum Chain
The Magnum Chain and 37/60 Granit Lock offer the greatest theft deterrent of any chain and lock combination we have ever found.  We went to experts in chain design and to criminals, found how they defeat chains and designed our chain to withstand the abuse thieves make on chains. 

To our knowledge, no one has managed to cut this chain, even with hydraulic bolt cutters. Yet we have been able to cut every competitive chain we have tested.
Each Magnum comes with a nylon sleeve, to protect your bikes finish.  You can purchase less expensive chains, but you can't buy anything this good.

Super Magnum Chain
The Super Magnum Chain and 37/80 Granit Lock now up the ante in security.  We took the regular Magnum Chain and lock and beefed up everything.  Germany has went and done the impossible and actually made the strongest chain and padlock combination even stronger.  The link diameter has been increased from 11mm to 12mm.  This increased the cross section surface area by 20% and the cutting resistance by 50%.  The lock has been improved as well.

Extreme Chain 59/12
This is what happens when ABUS Germany combines their very best products.
The 59/12 is constructed from the Super Magnum chain and the 59 Extreme U-lock.
This eliminates the use of a separate padlock allows absolutely no access into the device.
To make things worse, they added the new ABUS PLUS-X key system with 1 million key differs.

The Magnum Chains have three visible features not found elsewhere:
1) We use a longer end link through which the other end of the chain is inserted. Our lock holds only one chain-link resulting in absolutely no access anywhere.
2) there is no space between the links and
3) the cross section is hexagonal instead of round or square.
There are other important features built into the chain that are not obvious but do contribute to repelling attacks.  These design features add to the cost but dramatically increase the security of the chain.  
The Magnums come with a durable Nylon sleeve, to protect your bikes finish.  
You can purchase less expensive chains. It all comes down to how much your bike is worth to you.

Granit Lock 37/60 and 37/80

Other features include the patented  ABUS Plus^® 7 disc cylinder with 250.000 combinations and anti-drill plate and dust cover, shackle guard, and a tough plastic coating to protect your hands when used in extreme cold.

The Granit start with a special Molybdenum Chrome Nickel alloy.  The bodies are then milled to stringent specifications.  Then they are uniquely heat treated that makes them extremely hard yet not brittle.  This heat treating process has constantly improved over the last 20 years.  After that they are triple chrome plated to ensure excellent rust protection.
The shackles are made a similar way ensuring maximum protection against bolt cutters, while also supplying excellent resistance against freeze attacks.  These are the padlocks which every other padlock is compared to.

1. What material is the chain made of?
   We have seen 1" diameter chain cut like butter and we have seen 5/16" (8mm) shackles resist cutting like it was core hardened 10mm chain.  Why?  Because of the material it is made from and the hardening process.  The Magnum chain and lock are constructed of a special chrome molly tool steel which when properly hardened becomes virtually impervious to cutting while remaining ductile.  All of our locks are put through a freeze test at -40 degrees Celsius.  Freon and CO2 only get down to about -20 C.
2. What is the diameter of the chain?  The Magnum Chain is 11mm (7/16") and Super Magnum 12mm (15/32") in diameter.
   Usually, if the link is under 9.5mm, it won't matter what the link is made of or how hard it is, a good 3 foot bolt cutter will cut through it.
3. How is the chain hardened?  Case or Core, what's the difference?  How is hardness measured? Case hardening is very inexpensive and provides virtually no protection against bolt cutters.  The case hardening process is usually only a few thousandths of an inch deep.  An analogy would be a hard boiled egg.  Hard on the outside, but very soft on the inside.  Core hardening means it's the same hardness throughout the metal.   Core hardening is the only way to truly defeat bolt cutters assuming the link is thick enough.  Hardness is measured in Rockwell.  Example! The Magnum Lock and Chain is a minimum 65 Rockwell.  The higher the number the harder the material.  Files and hack saws are only about 58-61 Rockwell.  Ball bearings are about 63 Rockwell.   As you can see, the Magnum Lock and Chain is harder than a hack saw blade which means you will only dull the blade if it is used on the chain.  Bolt cutters are about the same hardness as the Magnum Chain.

If you are looking for the ultimate in protection, then the Magnum Chain and Padlock is the only choice.  Are there any drawbacks to this lock?   If you can handle lugging 11 to 15 pounds around, then no.  This lock is the one to be used at home or for long term storage. Is it possible to defeat this lock?  The straight forward answer is of course "Yes".   The Magnum Lock and Chain will defeat most conventional forms of attack, but there are some tools out there that will even cut through concrete walls.   Nothing will stop these, well, maybe a Smith and Wesson. Further, almost all of the motorcycle locks can be keyed to the same key!   Availability and lead time may vary depending on the exact set-up you select.

Shown here is the Magnum chain in combination with the 37 Quick Disc Lock. This combinations allows you to use the Disc Lock separate if needed. Add $20.00 (difference between 37/60 Padlock and 37 Quick) when ordering your chain.
