Having a set of tools is very important if you own a bike. You can never know when you’ll get a flat tire or need to change a broken or old chain. Therefore, your tool kit should include a bike chain tool to help you in maintaining your chain. The chain is part of the bike components that keep on moving and thus subject to wear and tear. 

To get the most out of it, you’ll need to lubricate it regularly and replace it periodically. While some bikes come with quick-release chains that don’t require any tools, others will require that you have the right tools to fix them on your bike. 

This review provides a guide to helping you select the best bike chain that you can use to break the chain and put it back together.

Why is a Bike Chain Tool Important?

Bike chain tools are quite easy to operate. They feature a punch that one has to advance to reach the pin that holds two links of the chain together. To break the chain links, one has to push the punch out. Although you can also use the same tool to connect broken chain links, the process is quite complicated.

Many new users consider bike chains only useful when replacing worn-out chains, but there are many instances that one can use this tool. You can use the tool to shorten a very long chain or use it to lengthen a shorter chain by joining two links together.

While other tools such as Allen keys and screwdrivers can come in handy when replacing chains, it’s advisable to use the right tool for the job. Chains are delicate and are easily damaged if one uses the wrong tool. Besides, bike chain tools are quite easy to use.

What to Look Out for When Getting the Best Bike Chain Tool

Bike chain tools are an essential part of your tool kit. However, there are many tools available on the market that can lead to confusion. Considering the following factors will help you in selecting the best bike chain tool that meets your needs.

Ease of Use

The design of tools ensures that work is easier and bike chain tools are no exception to this rule. It’ll be less frustrating to use a bike chain tool that’s easy to use, particularly if you’re a novice. Conversely, tools that aren’t easy to use can cause injuries when fixing or building your bike.

Type of Bike Chain Tool

Bike chain tools come in different designs that allow the user to easily break or fix a chain. The most common style featuring on many bike chain tools is the twist and screw style. However, some tools resemble pliers while others come as part of a set of tools. Choosing the right type of bike chain tool that meets your needs is vital.

Bike Chain Size

Select a bike chain tool that’s compatible with the drive train and chain. Most chains measure 3/32-inches while others are thicker at 1/8-inches. Ensuring that the bike tool fits the chain is an essential part of the selection process.

Bike Chain Speed 

Bike chain tools also come with specifications designed to match the chain speed. Many bikes today have chains with speeds ranging from 5 to 10. For maximum performance, the chain speed should match the bike chain tool.

The functionality of the Bike Chain Tool

The two main functions of these tools are to break chains and connect broken links. Many of the tools break chains hence known as bike chain breakers and bike chain splitters. You should match the functionality of the bike chain tool with your intended use.
