The answer to this query is a bit complex, but fear not, we’re here to shed some light on the topic.

The short answer is, yes, it is possible to fit an 11-speed cassette on a 10-speed hub, but there are a few considerations to keep in mind. Understanding the compatibility issues and limitations can help you make an informed decision on whether it’s worth pursuing this upgrade. So, let’s dive into the details and explore this fascinating topic further. Can you fit 11-speed cassette on a 10-speed hub? Let’s find out!

Can 11 Speed Cassette Fit On 10 Speed Hub?

Can You Fit an 11-Speed Cassette on a 10-Speed Hub

Upgrading your bike’s drivetrain can greatly enhance its performance, and knowing the compatibility between different components is crucial.

Understanding Cassette and Hub Compatibility

Before we delve deeper, let’s make sure we’re on the same page regarding cassettes and hubs. The cassette refers to the cluster of gears that sits on the rear wheel of your bike, while the hub is the central part of the wheel that the cassette attaches to.

In order for the cassette to function properly, there needs to be smooth engagement between the cassette’s freehub body and the hub.

Cassettes and hubs are designed to be compatible with specific numbers of speeds, referring to the number of gear combinations available. The cassette size and spacing between the gears differ between different speeds.

For example, a 10-speed cassette has narrower spacing compared to an 11-speed cassette. This difference in spacing is crucial to ensure smooth shifting and optimal performance.

Factors to Consider When Fitting an 11-Speed Cassette on a 10-Speed Hub

If you’re thinking about fitting an 11-speed cassette on a 10-speed hub, there are a few factors to consider to determine whether it’s possible:

Freehub Compatibility

The first and most important factor is the compatibility of the freehub body. The freehub body is the part of the hub that the cassette slides onto and is secured by a locknut. Different brands and models of hubs may have different freehub bodies with varying widths.

Most modern 10-speed hubs have a freehub body that can accommodate an 11-speed cassette, but it’s always important to check the manufacturer’s specifications to be certain.


One common method used to fit an 11-speed cassette on a 10-speed hub is by using spacers. Spacers are small metal or plastic rings that fit between the cassette and the freehub body, adjusting the spacing to match the narrower cassette.

By adding spacers, you can effectively convert your 10-speed hub into an 11-speed-compatible hub. However, keep in mind that this method may affect the shifting performance and durability of your drivetrain.


Dishing refers to the alignment of the rear wheel in relation to the centerline of the bike. When fitting an 11-speed cassette on a 10-speed hub, you may need to re-dish the wheel.

Re-dishing involves adjusting the spoke tension to align the wheel properly, ensuring that the cassette sits perfectly on the freehub body. This step is crucial to prevent misalignment and potential shifting issues.

Potential Issues and Considerations

While it may be possible to fit an 11-speed cassette on a 10-speed hub, there are some potential issues and considerations to keep in mind:

Shifting Performance

One of the main concerns when mixing different speed components is the shifting performance. The narrower spacing of an 11-speed cassette requires precise alignment of the derailleur and chain to ensure smooth and accurate shifts.

When using an 11-speed cassette on a 10-speed hub, you may experience suboptimal shifting, especially under load or during quick gear changes. Be prepared to make adjustments and fine-tuning to optimize the shifting performance.

Chain Compatibility

Another consideration is chain compatibility. The chain width for 10-speed and 11-speed drivetrains is different. While it’s possible to run an 11-speed chain on a 10-speed drivetrain, using a narrower 10-speed chain on an 11-speed cassette may cause chain slipping and potentially even damage the cassette. It’s crucial to ensure that your chain is compatible before attempting this mix.

Compatibility with Other Components

When upgrading or altering any part of your bike’s drivetrain, it’s essential to ensure compatibility with other components. The derailleur, shifters, and chainrings need to be compatible with the number of speeds on your cassette. If you decide to fit an 11-speed cassette on a 10-speed hub, make sure to check all the components’ compatibility before proceeding.

Seek Professional Advice

Modifying your bike’s drivetrain can be a complex task, especially when mixing different speed components. If you’re not confident in your mechanical skills or unsure about compatibility, it’s highly recommended to consult a professional bike mechanic. They have the expertise to assess compatibility, make necessary adjustments, and ensure your bike performs optimally.

Frequently Asked Questions

1. Can I put an 11-speed cassette on a 10-speed hub?

Yes, it is not recommended. 11-speed cassettes require a wider freehub body, which 10-speed hubs lack. Installing an 11-speed cassette on a 10-speed hub can lead to poor shifting and potential damage to the hub.

2. Will an 11-speed chain work with a 10-speed cassette?

No, it is not compatible. 11-speed chains are narrower than 10-speed chains and may not fit properly between the teeth of a 10-speed cassette. It is important to match the chain and cassette to ensure optimal performance and shifting.

3. Can I use a spacer to fit an 11-speed cassette on a 10-speed hub?

No, using a spacer will not make a 10-speed hub compatible with an 11-speed cassette. The spacer may cause misalignment and lead to shifting issues. It is best to use the appropriate hub and cassette combination for optimal performance.

4. Can I upgrade my 10-speed hub to accommodate an 11-speed cassette?

In most cases, no. Upgrading a 10-speed hub to fit an 11-speed cassette requires replacing the entire hub or wheel. The width and design of the hub are not compatible with the wider 11-speed cassette. It is more cost-effective to purchase a compatible hub or wheelset.

5. What are the alternatives if I want to use an 11-speed cassette?

If you want to use an 11-speed cassette, you will need to invest in a compatible hub, wheelset, or complete drivetrain upgrade. This ensures proper alignment, shifting, and overall performance. Consult a professional bike mechanic or local bike shop for the best options available for your specific bike model.

Final Thoughts

In conclusion, the question of whether one can fit an 11-speed cassette on a 10-speed hub arises when considering upgrading a bike’s drivetrain. After research and analysis, it is evident that this conversion is not directly compatible due to differences in spacing and cog width.

Attempting to force an 11-speed cassette onto a 10-speed hub can lead to poor shifting performance and potential damage to the components. Therefore, it is recommended to use a compatible 11-speed hub if you wish to upgrade to an 11-speed cassette.
