What to Look For When Buying a Chain Breaker Tool

best bicycle chain breaker tool

Before you buy the chain breaker tool for your bike, you will need to know different factors to consider before choosing one. These factors are clear indicators that you have chosen a high-quality product that is the right one for your bicycle. Please check on the list below:

The Right Fit

This factor is the most important to consider when choosing a chain breaker tool. Bike chains vary according to types, sizes, width, brands, etc. Meaning, you will need to find a chain breaker that can fit your bike’s chain style. For example, if you have a Shimano bike chain, a Shimano chain breaker can be an excellent option for you or chain breaker brands to fit a Shimano bike chain.

In relation to the fittings, every brand will let you know what type of bike chain will fit into their product. So, you must make sure that you know the type of chain in your bike so that it will be easy for you to find the brand that works on your bike chain. You must also remember that a chain breaker tool is universally designed, meaning it can also work not only on bicycle chains but others as well, such as motorcycles, ATVs, among others.

Quality

The quality of a chain breaker tool refers to its durability and toughness. And it covers everything, from its handle to the presser pin and the other parts of the bike tool. The chain breaker tool should be durable enough to withstand the pressure of removing the link’s pin. The handle should also provide comfort, especially in supporting the hand when applying pressure during the removal process. Some low-quality presser pins will just bend after only one usage. That is a clear indicator of a low-quality pin and a low-quality chain breaker tool.

You can also determine the quality of a chain breaker tool by the quality of its construction. It should use materials known to provide maximum strength and durability when used in the manufacturing process. My advice is for you to look for a chain breaker tool made with carbon steel, cast steel, and aluminum. Otherwise, you can research these materials to find their toughness and durability.

Ease of Usage

Not all chain breaker tools are easy to use. Some require additional tools to do it, while some require a learning curve to familiarize the process. However, some brands are easy to use and will not need additional tools to break a chain, just like some of the products shown in this review. I was more into those chain breaker tools that do not need any other tools to break a chain. Based on experience, these tools are well-made and durable enough to last longer compared to the other brands.

Additional Accessories

The more, the merrier is a quote that can also be applied in buying s chain breaker tool. If the product package comes with other accessories, then it should be worth the consideration. I mean, we have reviewed products that offer add-ons in the product package, such as an extra presser pin, a chain puller, and an extra hook. All of these accessories provide additional value to the product and should be an excellent addition to your bike toolbox.

Frequently Asked Questions

bike chain link removal tool

How to Use a Bicycle Chain Breaker Tool?

A chain breaker tool is used to resize a bike chain which means removing or adding a link into the chain. Different brands come with different processes but in general, here is how to use them:

First Step:

The first thing to do is unscrew the punch of the chain breaker tool and put the link you want to open in the slot dedicated for links.

Second Step:

This time, you will need to screw the punch in until it touches the head of the rivet, ensuring the punch rests in the center of the rivet head and that the other end of the rivet is not trapped by the body of the chain breaker tool. Screw the punch into the device to drive the rivet out of the front plate and through the rear plate.

Third Step:

When the rivet is almost through the rear plate, retract the punch and break the chain by flexing the links with your thumbs on the flat side. Check it immediately to avoid forcing the rivet right through the backplate. It is better to leave the rivet slightly protruding on the inside of the rear plate to help locate the hole when reconnecting the link.

How to Break a Bike Chain Without a Chain Breaker?

Yes, breaking a bike chain can be done without the use of a chain breaker tool. But, you will need to be careful as it requires tools that might bend or damage the chain. For example, you can use a hammer and a nail to remove the rivet and eventually remove the links, but you want to do it carefully since the hammer might damage the link. Some bikers use a grinder and a punch to grind the pin on the link and eventually remove the pin.

Conclusion

Having the best chain breaker tool in your bike box can be beneficial, especially in doing long rides. There will be moments that you will encounter a broken chain on the road, and the chain breaker tool will be an essential tool to help in repairing the bike chain. Many bikers underestimated the importance of this bike tool, but it is necessary and should have a space for your bike toolbox.
