Can I Use 10 Speed Chain on 9 Speed Cassette?

Are you looking to increase your bike gear ratio without purchasing a new cassette? Well, you can use a 10-speed chain on a 9-speed cassette. Chainring sizes vary depending on the gear ratio of your bike. So, if you have a 9-speed cassette and want to use a 10-speed chain, you’ll need to get a new chainring. But can I use 10 speed chain on 9 speed cassette? Let’s see the details.

If you try to use a 9-speed rear derailleur with a 10-speed chain and chainring, it will damage the chain or derailleur. It all depends on whether the bike’s components are 10-speed or 9-speed. In this article, I’ll explore the benefits of the 9-speed and 10-speed chains in detail. So, Let’s move!

What is a 10-speed chain and what does it do?

It is a bicycle chain with 10 links instead of the usual 6. Compared to the standard size, a 10-speed chain requires more link movement with each rotation and offers more torque due to increased chain length. Despite its higher maintenance requirements, it is lighter and easier to use than a standard bike chain. Some riders may prefer this kind of chain due to its size, which allows them to carry larger items like panniers or cargo boxes.

A 10-speed bicycle chain is called a double or a ten-speed chain because it has ten fewer cogs in its link. The size of the chain depends on the number of cogs, but on average, it is about one and a half times longer than that of the typical six-speed bicycle chain. Usually, 10- speed chains are made from steel or aluminum, with only a few models made from titanium or carbon fiber. Many modern bikes use a 10-speed chain, but older and mountain bikes use a six-speed chain.

Another advantage is carrying more weight in the cargo space because it has ten more links. There are also fewer derailleurs and chains problems than in a 6-speed chain. On the other hand, there are some drawbacks. The higher maintenance requirements include lubrication and cleaning to avoid rusting or damage from dirt accumulation. Moreover, it is not favored by experienced cyclists or those who ride long distances because of its increased tendency to break compared with the six-speed bicycle chains.

What are the benefits of using a 10-speed chain on a 9-speed cassette?

Your bike is a machine that should last a lifetime, and proper maintenance ensures that it will run smoothly and reliably. A chain can stretch, but it’s a task that should be done by a professional. It offers replacement parts and services that will keep your bike running at peak performance for many years. The most important part of any drivetrain is the chain and your local bike shop will be able to help you evaluate the best option for your riding style and type of bike.

When changing a chain, make sure you purchase one that will also work with your cassette. You’re better off buying a completely new drivetrain than replacing parts that won’t fit the bike. The benefit of 10-speed chains is that they will fit on a 9-speed cassette. Hanging onto your rear derailleur and shifters will also decrease costs when you buy a new cassette. Another benefit is that they are a bit more expensive than cassettes and chains that will fit on 8-speed systems.

A 10-speed cassette offers a wider range of gears for climbing and descending. The two largest sprockets are larger than on 9-speed so you can climb steeper hills with less effort. The two smallest sprockets are also smaller, so you’ll have to back peddle a little slower when going downhill with your bike’s brakes on. If you’re planning a ride that involves riding uphill or downhill, then the 10-speed drivetrain will be more beneficial to your needs.

Can I use a 10-speed chain on my 9-speed cassette?

If you own a nine-speed cassette and a ten-speed chain, it’s possible to fit the two together. However, the result is not as smooth as you’d get from a dedicated nine-speed or ten-speed setup. The 10-speed chain can cause wear on the 9-speed cassette and create a grinding noise. Here’s how to adapt the chain, use it successfully and keep it quiet.

The right type of chain 

10 speed chain is made with 10 different-sized links. Some of the chains used in this project have links of 3 mm and 5 mm in size. It is large enough to get some friction rolling but small enough that the chain does not interfere with the cassette teeth.

The right parts

It would help if you had a chain, cassette and a sprocket tool to complete this exercise. The sprocket tool has a special disc that fits over the drive sprocket on the rear wheel. It is used to remove the chain and set it up for reinstallation in three easy steps. There are two types of cassettes: one with one chain and one with two chains.

Get out your tools

The instructions show you how to install a single-chain cassette. A two-chain cassette has extra links on the second side that sit just behind the first chain, allowing you to use all 10 drive sprockets on both sides of the bike.

Get the chain installed

After you have the sprocket tool in place, it’s time to fit the chain around the cassette and over the rear wheel. The 10-speed chain is long, so you must spread it out a bit as you rotate it around the back wheel. You’ll also need to hold it as you install each link.

Adjust for length

Once you have all the links on, it’s time to adjust the length of the chain. The 10-speed chain is longer than a typical 9-speed chain, so it’s quite possible to exceed the limit on your derailleur with this step. The best way to adjust it shorter is to use a chain tool. If you don’t have one, you can use an Allen wrench or screwdriver instead of a chain tool. If you are short on tools, it’s best to replace the whole thing.

How to use a 10-speed chain on a 9-speed cassette?

If you’re old enough to remember Dynohub, you might remember that the original freewheels were pinned together. To use the Dynohub, you needed to take a special tool and bend the chain. This same principle is at play when using a 10-speed chain on a 9-speed cassette.

This principle is the same for any road bike with a double or triple crankset, and the front and rear derailleurs are generally the same sizes. For example, the 9-speed cassette would be between 8 and 11 teeth on a mountain bike. On a road bike, that would be around 30 or so teeth. So while you might have a 9-speed chain on your mountain bike with the first couple of links removed, you should never use an older 10-speed chain.

The main advantage of 10-speed chains for older bikes is that they can be used on new bikes with 9-speed cassettes already installed. Many new bikes come with a 9-speed cassette already installed in the shift cogs and 10-speed chains. It would help if you never used a 10-speed chain with a 9-speed cassette. You should use an old 8 or 9-speed chain on the cassette. If you are using a newer 10-speed chain, it will have to be used with a 9-speed cassette. You can convert the cassette to work with a 10-speed chain by removing one of the shift sprockets.

The Pros and Cons of using a 10-speed chain on a 9-speed cassette:

The Pros and Cons of using a 10-speed chain on a 9-speed cassette is an article about what might happen if you attempt this fix without professional help. The main pros of using a 10-speed chain on your 9-speed cassette are that it is cheap and will immediately get you back on the road. Also, if you have a bike shop nearby, they will be able to install it for you in no time, leaving you with your new bike.

  • You can increase your level of fitness by working harder to maintain power.
  • The additional strength from the larger gear allows you to stay in high gears for longer, reducing stress on the drivetrain components and improving overall bike performance.
  • You can reduce muscle strain by not having to shift so much.
  • It will help you push harder on climbs, improving your overall fitness by making you stronger and helping you ride better in high gear.

The main cons of using a 10-speed chain on a 9-speed cassette are that it will restrict your riding options. Also, you’ll be limited in your gear ratio choices because there will not be a middle sprocket and the last one will not be used.

  • It will be heavier, thus making it more difficult to climb hills.
  • The extra strength required to use the larger chainring will also increase the stress on your arm, impacting overall performance and fitness.
  • You will not be able to carry as much gear because of the heavier chainring.


Chain size is a personal preference and will affect the speed of your bicycle. Changing chain size will affect the gear ratio, meaning some gears may be unusable. Those who think they can use a 10 speed chain on a 9 speed cassette might be able to, but you could risk breaking the chain. The main reason is that the gear ratios would be off, and you would likely experience decreased efficiency and performance. So, if you need a new chain, go with a 10 speed option. Additionally, replace your cassette and sprocket if your bike is over ten years old.
