Best Security Chain - Buyers’ Guide

What are some factors to think about when purchasing a security chain?

Here are some factors that you should keep in mind before purchasing a security chain:

  • The Area Where You’ll be Parking your Bike

It’s important for you to assess the area where you’ll be riding your bike as well as the places where the bike will be parked. If you live in a relatively low to moderate-risk area then you could get away with having a lightweight security chain for your bike. However, if you live in a high-risk area, then you may want to invest in a heavy-duty security chain. It's important for it to be able to withstand attacks from stronger tools and techniques.

  • Size, Weight and Dimensions

You definitely want to buy a security chain that’s durable but at the same time, you have to strike a balance with its level of portability as well. It’s very likely that you will stop using your security chain if you find it inconvenient to carry around with you every time you go out riding on your bike.

You also have to think about the length of the security chain and determine how long of a chain you need. You can help determine this by thinking about how you normally lock your bike. Do you lock it to a solid structure or do you immobilize the wheel by tying it to the bike frame? All of these questions will help you decide how long of a security chain you need. 

  • Brand

If you’re the kind of person that likes to try out new brands, we urge you to go against your instincts when it comes to security chains. You should definitely go for dependable brands that have been developing security chains for years. These are companies that have a good reputation and produce chains that can withstand all sorts of attacks. A security chain is a product that should definitely be bought from a trusted brand. This is because if you opt for one from a lesser-known brand and it turns out to be sub-par, you could end up getting your bike stolen.

  • Product Reviews

Product reviews when it comes to security chains are a gold mine of information that can really help you gauge the quality of certain products. They often have insight into the weaknesses of certain locks and whether they can be broken into using certain techniques or not.

Reading them before you decide on a product can definitely help you find out whether that product is secure enough for you or not. 

How secure are security chains?

Security chains are one of the most secure types of bike locks. They are flexible and easy to use. If you pair them up with a U-lock or a padlock, this is the safest form of a lock that you can have for your bike. High-end security chains are thick and often made from dense material such as hardened manganese steel. This makes them extremely difficult to cut through even with strong tools such as angle grinders.

How can I judge how secure a particular security chain is?

You can inspect it yourself and determine whether thickness, sturdiness and material of the product seem secure enough to you or not.

You can also look online towards different companies that test security chains and locks. These come out and give them a rating based on how secure they are such as Sold Secure. 

What materials are security chains normally made of?

Different manufacturers experiment with different types of material to make their security chains. As we mentioned earlier, a lot of companies opt for a manganese steel compound. This gives their security chains a strong, durable exterior that is very resistant to cutting as well as leverage attacks.

Many bike chains and protector lock chains are also constructed from CRMO (Chromium and Molybdenum).

Boron Manganese Steel is another alloy that is impenetrable to regular cutting attacks. It does need to be hardened properly, however.

Best Security Chain - FAQs

Can bolt cutters cut through a security chain?

No. Most high-end security chains feature links that are shaped in the form of either a hexagon, trapezoid or square. These unique shapes of the links make it nearly impossible for bolt cutters to get a grip on to them. Even if a thief is somehow able to get a grip onto such a chain, they are thick enough to not be cut. It’s virtually impossible for any human to have enough strength to cut through them using just bolt cutters.

Is it possible to find a security chain that is impossible to cut?

You can’t really say a security chain is impossible to cut as, given enough time and resources, any security chain can be cut no matter how durable it is.

However, you can definitely strive to get a security chain that takes a lot of time and resources in order to be cut. A thief does not usually have a lot of time and they can only carry tools that are portable. Due to these two facts, you can definitely find a security chain that would be strong enough for any thief to get through. 

What are people referring to when they say “through hardened”?

Through-hardening is a process that involves a rapid quench of an alloy. This increases its overall hardness throughout its entire thickness.

What are some reliable brands when it comes to security chains?

Some reliable brands that have been manufacturing security chains for decades are: 
  • Kryptonite 
  • Schlage
  • Abus
  • AKM

Can hardened steel be cut with bolt cutters?

It is very difficult to get through a hardened-steel chain with bolt cutters. This is because a hardened steel chain is hardened throughout its thickness. The flat shape of their links distributes the force of the bolt cutter’s jaw throughout the chain, thereby diffusing its pressure.

Which is better for security: cable or chain?

A security chain is definitely a lot better for security than a standard cable lock. A regular petty thief can get through a cable lock using standard tools such as bolt cutters or a hacksaw. On the other hand, a security chain demands extremely strong tools as well as a lot of time in order to be cut through.

How can I judge how thick my chain should be?

You can determine this by thinking about how secure you want it to be and balance it with how portable you want it to be. It’s also important to think about where you’ll be using it to secure your bike. Ensure that the security chain is thin enough to pass through your bike’s frame or through whatever structure you intend to chain your bike to, etc. 

Final Verdict

Security chains are an important type of bike lock that provide great security and peace of mind to bike owners everywhere. It’s important to do your research and find a high-quality security chain so it won’t be easily defeated by common techniques and tools that thieves use.

After months of testing and research, we have to crown the Kryptonite New York FAHGETTABOUDIT as the winner. It’s astoundingly sturdy, corrosion-resistant and it comes with a convenient LED key too.
