If you’re an avid mountain biker, chances are you’ve encountered situations where you need to adjust or replace your MTB fork steerer tube. Whether it’s to achieve a more comfortable riding position or to fit a new fork, knowing how to cut the steerer tube is a valuable skill that every rider should have.
Before we dive into the process, it’s important to note that cutting a MTB fork steerer tube should be done with caution, as an incorrect cut can lead to a compromised structural integrity and safety of your bike. Therefore, it’s essential to follow the proper steps and take necessary precautions to ensure a precise and accurate cut.
Step 1: Measure and Mark
Begin by determining the desired length of your steerer tube. This will depend on your riding style, bike fit, and personal preference. Once you have decided on the length, use a ruler or tape measure to mark the cutting point on the steerer tube. Make sure the mark is clear and easily visible.
Disclaimer: If you are unsure about how much to cut, or if you don’t have the necessary tools or expertise, it is recommended to seek professional help or guidance from a knowledgeable bike mechanic.
What is MTB Fork Steerer Tube?
The MTB fork steerer tube is a key component of a mountain bike’s suspension system. It is the tube that connects the fork to the bike’s frame and allows the rider to steer the bike. The steerer tube is typically made of metal, such as aluminum or steel, and is threaded at one end to allow the stem and handlebars to be securely attached.
The length of the steerer tube can vary depending on the bike frame size and the desired ride height of the rider. It is important to have the correct length of steerer tube to ensure proper handling and control of the bike. If the steerer tube is too short, it may not fit properly in the frame or may limit the adjustability of the handlebar height. On the other hand, if the steerer tube is too long, it can lead to an uncomfortable riding position or interfere with the bike’s suspension travel.
When cutting an MTB fork steerer tube, it is crucial to use the correct tools and techniques to avoid damaging the tube or the bike frame. It is recommended to seek professional assistance or guidance if you are not confident in performing this task yourself. Improper cutting of the steerer tube can result in a compromised structural integrity of the bike and may lead to accidents or injuries while riding.
Why Would You Want to Cut MTB Fork Steerer Tube?
The fork steerer tube is an integral part of a mountain bike fork, connecting the upper and lower parts of the fork and allowing it to steer. However, there are several reasons why you might want to cut the MTB fork steerer tube:
-
Custom Fit:
By cutting the steerer tube, you can customize the height of your handlebars and the overall fit of your bike. This can be particularly useful if you have a new frame or want to change the bike’s geometry to match your riding style and preferences.
-
Weight Reduction:
The steerer tube is usually made of aluminum or carbon fiber, both of which can add significant weight to your bike. By cutting the tube, you can remove excess material and reduce the weight of your fork, improving the bike’s overall performance.
-
Aesthetics:
Some mountain bikers may choose to cut the steerer tube for purely aesthetic reasons. By reducing the height of the tube, you can achieve a sleeker and more streamlined look for your bike.
Before deciding to cut your MTB fork steerer tube, it is important to consider the potential implications and make sure you have the right tools and knowledge to do it properly. If you are unsure or uncomfortable with this process, it is recommended to seek advice from a professional bike mechanic.

Step-by-Step Guide to Cutting MTB Fork Steerer Tube
When setting up or making adjustments to your mountain bike (MTB), you may find that the steerer tube of the fork needs to be cut to the correct length. This can be intimidating if you have never done it before, but with the right tools and some careful steps, you can easily cut your MTB fork steerer tube. Here is a step-by-step guide to help you through the process:
Required Tools:
- MTB fork with an uncut steerer tube
- Hacksaw or pipe cutter
- Carbon fiber cutting guide (if you have a carbon steerer tube)
- Masking tape
- Measuring tape or ruler
- Marker or pen
Step 1: Measure and Mark
Start by deciding how long you want your steerer tube to be. Ideally, you should consult the manufacturer’s guidelines or seek professional advice to determine the correct length for your bike and riding style. Once you have the desired length, measure and mark it on the steerer tube using a marker or pen. It’s important to make a clear and visible mark so that you can cut accurately.
Step 2: Secure the fork
Before cutting, it’s crucial to secure the fork in a vice or a suitable clamp to prevent it from moving while you’re cutting. Make sure the fork is firmly held in place and won’t slip or rotate during the process. This will ensure a precise and straight cut.
Step 3: Wrap with masking tape
To protect the surface of your steerer tube and minimize the chance of accidental scratching, wrap masking tape around the part of the tube that will be cut. This will act as a protective layer and preserve the aesthetics of your fork.
Step 4: Cut the steerer tube
If you’re using a hacksaw, make sure you have a fresh blade that is suitable for cutting metal or carbon. Place the blade on the marked line and start cutting through the steerer tube with smooth and steady strokes. Take your time and be cautious not to rush. If you have a pipe cutter, follow the manufacturer’s instructions for cutting through the tube.
Step 5: Remove burrs and smooth edges
After the cutting is complete, use a file or sandpaper to remove any sharp burrs and smooth the edges of the cut. This will prevent any potential injuries and ensure a clean finish.
Step 6: Clean and reassemble
After you have finished cutting and smoothing the steerer tube, clean off any debris or metal shavings. Then, reassemble the fork onto your bike with the appropriate spacers and stem. Make sure the headset is properly adjusted before you go for a ride.
With these step-by-step instructions, you can confidently cut your MTB fork steerer tube to the correct length. Remember to measure carefully, take your time, and prioritize safety throughout the process. If you feel unsure or uncomfortable with any of the steps, it’s always a good idea to seek professional help or advice.
Step 1: Measure and Mark
Before you can begin cutting your MTB fork steerer tube, it’s important to first measure and mark the desired length. This will ensure that you end up with the perfect fit for your bike.
Start by removing the fork from the bike and securing it in a stable position. Use a ruler or a tape measure to measure the current length of the steerer tube.
Things you will need:
- Ruler or tape measure
- Marker or pencil
- Fork cutting guide (optional)
Once you have the measurement, make sure to subtract the length of any spacers or headset components that will be installed on top of the steerer tube. This will ensure that the final length is perfect.
Once you have the final measurement, mark the point on the steerer tube where you will be cutting. You can use a marker or a pencil to make a clear and visible mark. If you have a fork cutting guide, you can use it to help make a straight and accurate cut.
It’s important to double-check the measurement and mark before proceeding to ensure accuracy. Cutting too much of the steerer tube can lead to a poor fit and potential safety issues.
