Do you have a BMX bike and are wondering what size chain you need? Well, you’ve come to the right place! In this complete guide, we will cover everything you need to know about chain sizes for BMX bikes.
What size chain do i need for my BMX bike?
BMX chains come in two different widths, 1/8” and 3/32”:
1/8” chains are typically used on freestyle BMX bikes. They’re thicker and stronger than 3/32” chains, making them better suited for riding on ramps, grinds, and other tricks where there’s a lot of stress on the chain.
3/32” chains are most often used on race BMX bikes. They’re thinner and lighter than 1/8” chains, making them better suited for pedaling quickly.
One of the most essential parts of a BMX bike is the chain. The chain is responsible for transferring the power from the pedals to the wheels, which propels the bike forward. Without a properly functioning chain, a BMX bike is effectively useless.
Things to consider when selecting a chain for BMX bike
1. The Drivetrain
First, you need to know the size of your bike’s drivetrain. The drivetrain is the part of the bike that includes the chain, sprockets, and cranks. The drivetrain size will determine the width of the chain you need.
2. Width of the chain
BMX chains are available in two different widths, 1/8″ and 3/32″. The vast majority of BMX bikes use a 3/32″ chain. If you have a BMX bike with a 1/8″ drivetrain, you will need to use a 1/8″ chain. If you have a BMX bike with a 3/32″ drivetrain, you can use 3/32″ chain.
3. Size of the wheel
You need to know the size of your wheels. This will determine the length of the chain you need. BMX chains are available in two different lengths, 25″ and 27″. If you have a BMX bike with 20″ wheels, you will need a 25″ chain. If you have a BMX bike with 24″ wheels, you will need a 27″ chain.
4. Pay attention to Master Link
You should also keep in mind that when installing a new chain on your BMX bike, it is important to pay attention to the master link. The master link is the link that allows you to take the chain on and off the bike.
Most BMX chains come with a master link that is not compatible with all drivetrains. If you have a 1/8″ drivetrain, you will need to use a master link that is specifically designed for 1/8″ chains. If you have a 3/32″ drivetrain, you can use either a 1/8″ or 3/32″ master link.
5. Type of Riding
The final thing to consider is the type of riding you’ll be doing. If you’re planning on doing a lot of jumps and tricks, you’ll need a heavier-duty chain. Conversely, if you’re just going to be cruising around, you can get away with a lighter-duty chain.
How to install a new chain on your bike?
Now that you know what type of chain you need for your BMX bike you can go ahead with installing it. Fitting a new chain on your BMX bike is a relatively simple process.
First, remove the old chain from the bike. Next, thread the new chain through the drivetrain, starting at the rear sprocket and ending at the front sprocket.
Then, connect the two ends of the chain together using the master link. Once the chain is installed, you can adjust the tension as needed.
How to Measure aBike Chain Size?
You can measure the inner and outer widths of your bicycle with a ruler or caliper to determine the chain size of your bike.
Number of Links That Are ina Bike Chain?
Here’s a quick rundown of BMX bike chain sizes and the corresponding number of links:
- -14″ bike: 41-43 links
- -16″ bike: 44-46 links
- -18″ bike: 47-49 links
- -20″ bike: 50-52 links
As you can see the larger the chain size the more links you will need.
How to Know Which Bike Chain to Buy?
If you are considering buying a bike chain the most important factors you need to consider are the size of the chain, the type of chain, and the length of the chain.
How Long Should My Chain Be?
If you’re not sure how long your bike chain should be, then a good rule of thumb is to start with a 21″ chain and then shorten it as needed. You can always add links to a chain, but it’s much more difficult to remove them.
So, which chain size is right for you? It really depends on the factors mentioned above. To err on the side of caution, we recommend going with a longer chain. That way, you can always shorten it if needed.
