What is a BMX Chain

Firstly we need to learn why BMX bikes have chains that are wider than other bicycle chains. These BMX chain sizes are specifically designed for BMX Bikes. These chains are typically wider, more solid, and more robust than the general type of bicycles. They are built to resist the high pressures and impacts expected in BMX riding, as these bikes are used for jumps and stunts. 

What Size BMX Chain Do I Need 

BMX chains are available in a variety of sizes. The most common standard BMX chain sizes are 1/8″ and 3/32″. The width of the chain’s links refers to its size, the chain with 1/8″ size being wider than 3/32″ chains. The wider chain size is preferred for freestyle BMX riding, whereas the narrower size is preferred for BMX racing.

1/8 “Chains for BMX

A 1/8″ chain is the most common type of chain used in freestyle BMX riding. What is the best BMX chain? These chains are broader and more potent than 3/32 “chains, making them a better option to withstand the stresses and effects of freestyle riding. Aside from being more comprehensive, 1/8 ” chains are made from solid materials, such as heat-treated steel or Chromoly, to bear strains. That’s why they are considered the strongest BMX chains. 

3/32″ BMX Chains

3/32″ BMX chains are narrower than 1/8″ chains, making them lighter and more efficient. The thin chain will make them a popular choice for BMX racing, where riders focus on speed and efficiency. However, As they are narrower, 3/32″ chains are not as strong as 1/8″ chains, making them less suitable for freestyle BMX riding.

Heavy-Duty Chain

Heavy-duty chains are designed for aggressive BMX riding and are typically more substantial and durable than standard BMX chains. These chains are designed to handle the strains of jumps and stunts. Commonly they are available in lengths ranging from 96 to 112 links.

Half-Link Chain

Half-link chains are designed for more precise chain adjustments. These chains have links half the width of a standard chain, allowing for finer adjustments for BMX riders. Half-link chains are generally available in lengths of 100 or 102 links.

Race Chain

Race chains are made specifically for BMX racing and are typically narrower and lighter than standard. These chains are designed for riders who want the most efficient power transfer. They are available in lengths ranging from 98 to 106 links.

Single-Speed Chain

Single-speed chains are designed for bikes with a single gear. They are also broader and more potent than standard BMX chains. These chains are available in lengths ranging from 98 to 112 links and are designed to handle the stresses of single-speed riding. 

Master Link Chain

Master link chains are designed for riders who need to frequently remove their chain, such as cleaning or replacing a worn-out chain. You must know how to install BMX chain with a specially designed BMX tool. These chains have a master link that allows for easy removal and installation of the chain. Master link chains are available in various widths, lengths, and strengths.

After getting the basic idea of chain sizes, you can determine the right size of BMX chain for your bike by measuring the length of your existing chain or chainstay.

How to Measure the Chain Width

The easiest way to find the correct size for your bike chain is to consult the manufacturer’s specifications. Furthermore, this information is also available on the website of the BMX bikes or in the owner’s manual. 

If you need access to the manufacturer’s specifications, you can measure the width of your bike’s chainstay. The chainstay is the frame section that runs from the bottom bracket to the rear dropouts, where the rear wheel is connected to the frame. Measure the distance between the inside of the two dropouts with a ruler or measurement tape to determine the chainstay width.

Once you know the width of your chainstay, you can use it to calculate the correct chain size. If your chainstay is 1/8″ or wide, you should use a 1/8″ chain. If your chainstay is narrower than 1/8″, a 3/32″ chain will be more suitable. 

How Do I Determine the Right Length

In addition to width, chain length is another critical consideration when choosing a BMX chain. A chain that is too short can cause excessive tension on the drivetrain and potentially damage the chain or other components, while a chain that is too long can increase the risk of chain slippage or get caught on obstacles. 

To determine the correct BMX chain length for your bike, you’ll need to measure the distance between the center of the front chainring and the center of the rear cog to know how many links does a BMX chain have? Most BMX chains are sold in lengths ranging from 90 to 120 links. 

Manufacturing-Specific Factors to Consider:

These are manufacturing-specific factors to consider when selecting a BMX chain: 

Chain Strength

BMX riding puts a lot of strain on the chain, and choosing a chain that can withstand the demands of your riding style is critical. Look for chains made of high-quality materials, such as heat-treated steel, designed explicitly for BMX riding.

Chain Durability

Along with the chain’s strength, you also need to consider the chain’s durability. Look for chains resistant to wear and tear and have been tested to withstand the impacts and stresses of BMX riding. Chains treated with anti-corrosion coatings or using high-quality lubricants along with the BMX chain guard cover can also help extend your chain’s life.

Chain Weight

BMX riders must also be mindful of their BMX chain weight. A heavier chain will slow you down and make it more difficult to perform tricks or jumps. Look for lightweight chains that are strong and durable.

Chain Compatibility

Finally, ensure that the chain you choose is compatible with the rest of the components on your BMX bike. The chainring, cassette, and rear derailleur are all the parts to be considered. Ensure the chain you choose is compatible with your specific drivetrain and is the correct length for your bike.
