What is a threadless headset?
A threadless headset is a type of bicycle headset that does not use threaded components to attach the fork to the frame. Instead of a threaded steering column, a threadless headset uses a stem and a series of spacers to secure the fork in place. This design provides several advantages over traditional threaded headsets, including increased stiffness and easier adjustment.
Components of a threadless headset:
A threadless headset consists of several key components:
- Steering column: The steering column is the tube that extends from the frame and connects to the fork. It provides the interface for the stem.
- Stem: The stem is the component that holds the handlebars and connects to the steering column. It typically clamps onto the steering column using bolts.
- Spacers: Spacers are used to adjust the height of the stem, allowing for a customized riding position. They can be added or removed as needed.
Advantages of a threadless headset:
There are several advantages to using a threadless headset:
- Stiffness: The threadless design provides increased stiffness and rigidity compared to threaded headsets. This results in more precise steering and improved handling.
- Easier adjustment: Adjusting the height and angle of the handlebars is easier with a threadless headset. The stem can be easily loosened, repositioned, and tightened without the need for special tools.
- Compatibility: Threadless headsets are compatible with a wide range of fork and frame sizes, making it easier to find replacement parts or upgrade components.
Overall, a threadless headset is a versatile and durable option for cyclists looking to improve their bike’s performance and make adjustments to their riding position.

Preparations
Before replacing the forks on a threadless headset, it’s important to gather all the necessary tools and materials. Here’s what you’ll need:
Tools:
- Allen wrench set
- Adjustable wrench
- Threadless headset press or crown race setter
- Bearing grease
Materials:
- New forks
- New headset bearings
- New headset spacers
Make sure you have all the tools and materials readily available before starting the replacement process. It’s also a good idea to have a clean and well-lit workspace to work in. Once you have everything prepared, you’ll be ready to proceed with replacing the forks on your threadless headset.
Gather the necessary tools
Before you begin replacing the forks on your threadless headset, it is important to gather all the necessary tools to ensure a smooth and successful installation. Having the right tools on hand will make the process easier and prevent any potential damage or complications.
Here are the tools you will need:
- Allen wrench set (usually 5mm and 6mm)
- Adjustable wrench
- Headset press or a rubber mallet and a piece of wood
- Grease
- New forks and headset bearings
The Allen wrench set will be used to remove the bolts and screws that hold the old forks in place. The adjustable wrench will be needed to loosen and tighten the headset top cap and stem bolts.
If you have a headset press, this will make the installation process easier and more precise. However, if you don’t have a press, you can use a rubber mallet and a piece of wood as an alternative. This will allow you to gently tap the new forks into place without causing any damage.
Grease is essential for lubricating the headset bearings, ensuring smooth rotation and preventing premature wear. Make sure you have enough grease on hand for the installation.
Lastly, you will need the new forks and headset bearings themselves. Ensure that you have the correct size and style of forks that are compatible with your frame and other components.
By gathering all of these tools beforehand, you will be well-prepared to replace the forks on your threadless headset and complete the installation with ease.
Remove the front wheel
To begin replacing the forks on a threadless headset, the first step is to remove the front wheel. This will provide easier access to the rest of the headset components. Follow these simple steps:
- Start by loosening the quick release lever or unfastening the axle nuts, depending on the type of wheel attachment.
- Gently pull the wheel out of the fork dropouts, ensuring not to damage the brake pads if you have disc brakes.
- If you have rim brakes, remember to disengage the brake caliper from the rim by releasing the brake cable tension or unhooking the brake arms.
- Set the front wheel aside in a safe place to prevent any damage or tripping hazards.
Now that the front wheel is removed, you can proceed with the next steps to replace the forks on your threadless headset.
Steps to replace the forks threadless headset
Replacing the forks threadless headset on your bike can be a straightforward process if you follow the right steps. Here are the steps you should take:
Step 1: Gather the necessary tools
Before getting started, ensure you have the right tools. You will need a wrench or a hex key, a hammer, and a pipe cutter or a hacksaw.
Step 2: Remove the old headset
Start by removing the stem, the spacers, and the top cap. Use the wrench or hex key to loosen the bolts holding them in place. Once these components are removed, you can unscrew the forks from the frame.
Step 3: Install the new headset
Place the new headset onto the frame, ensuring it is properly aligned. Attach the forks to the frame, making sure they are securely fastened. Use the wrench or hex key to tighten the bolts.
Step 4: Cut the steerer tube, if necessary
If the steerer tube on the new forks is too long, you may need to cut it to the desired length. Measure the tube, mark the desired cutting point, and use the pipe cutter or hacksaw to trim it down. Be careful to make a clean and straight cut.
Step 5: Reassemble the headset
Once the steerer tube is cut, reattach the stem, spacers, and top cap. Make sure they are tightened securely. Double-check that the forks move smoothly when turning the handlebars.
By following these steps, you should be able to successfully replace the forks threadless headset on your bike. Remember to exercise caution and consult a professional if you are unsure about any part of the process.
Step 1: Loosen the stem bolts
Before you can replace the fork on a threadless headset, you’ll need to loosen the stem bolts. This will allow you to remove the stem from the steerer tube and access the fork.
Start by locating the stem bolts, which are typically located on the top of the stem. Using an appropriate Allen key or wrench, loosen the bolts by turning them counterclockwise. Be sure to loosen all the bolts evenly to prevent any uneven pressure or damage to the stem.
Once the stem bolts are loose enough, you can then gently tap on the top of the stem with a rubber mallet or a block of wood to help break any remaining tension. This will allow the stem to easily slide off the steerer tube.
With the stem removed, you now have access to the fork and can proceed with replacing it. Remember to keep track of any spacers or washers that may be present, and make note of their positioning before removing them.
Step 2: Remove the stem and handlebars
Before you can replace the fork’s threadless headset, you need to remove the stem and handlebars. Follow these steps to do so:
- Loosen the stem bolts using an Allen wrench or a suitable tool. There are usually two bolts that hold the stem in place.
- Once the bolts are loosened, lift the stem off the fork steerer tube.
- Next, remove the handlebars from the stem. This may involve loosening additional bolts or screws depending on the type of handlebars you have.
- Gently slide the handlebars out of the stem, being careful not to damage any cables or housing that may be attached.
- With the stem and handlebars removed, set them aside in a safe place.
Now that the stem and handlebars are out of the way, you can move on to the next step of replacing the fork’s threadless headset.
