If you’re an avid cyclist, you know how important it is to have a properly functioning fork on your mountain bike. The Suntour XCM fork is a popular choice for many riders due to its durability and performance. However, over time, the fork lockout mechanism may become worn or damaged, preventing you from effectively locking or unlocking the fork.
Fortunately, replacing the Suntour XCM fork lockout is a relatively straightforward process that you can do yourself with just a few tools and a bit of know-how. In this article, we’ll walk you through the steps necessary to successfully replace the lockout, ensuring that your fork operates smoothly and efficiently.
Step 1: Prepare Your Workspace
Before diving into the replacement process, it’s essential to create a clean and organized workspace. Clear a table or workbench and gather the necessary tools, including a set of Allen wrenches, a cable cutter, and a replacement lockout mechanism specific to your Suntour XCM fork model.
Tip: Check the user manual or Suntour’s website to ensure you have the correct replacement part for your fork model.
What is a Suntour XCM fork lockout?
The Suntour XCM fork lockout is a feature found on certain mountain bike forks that allows the rider to lock out the fork’s suspension for more efficient climbing or smooth road riding. It is a mechanism that controls the movement of the fork’s suspension, preventing it from compressing and rebounding when engaged.
When the fork lockout is engaged, the suspension is essentially “locked” in place, providing a rigid front end and eliminating the bobbing and bouncing typically associated with suspension forks. This can be particularly useful on smooth or uphill surfaces where a locked-out fork can improve pedaling efficiency and reduce energy loss.
How does it work?
The Suntour XCM fork lockout is typically controlled by a lever or switch located on the fork itself. When the lever or switch is flipped or pushed, it activates the lockout mechanism, which disables the fork’s suspension. This is usually achieved by blocking the flow of oil within the fork, preventing the suspension from moving and compressing.
When the lockout is engaged, the fork becomes rigid, allowing for more controlled handling and improved power transfer. However, it is important to note that using the lockout on rough or uneven terrain can greatly reduce the fork’s ability to absorb impacts and may result in a harsh and uncomfortable ride.
How to replace a Suntour XCM fork lockout?
To replace a Suntour XCM fork lockout, you will need to follow these steps:
- Start by removing the old fork lockout lever or switch. This may require using a wrench or Allen key to loosen and remove any bolts or screws holding it in place.
- Once the old lockout mechanism has been removed, carefully inspect the fork for any damage or wear that may require additional repairs or replacements.
- Next, install the new Suntour XCM fork lockout by following the manufacturer’s instructions. This may involve attaching the lever or switch to the fork using the provided hardware.
- Once the new lockout mechanism is securely in place, test its functionality by engaging and disengaging the lockout several times. Make sure it moves smoothly and locks the fork as intended.
- Finally, take your bike for a test ride to ensure that the new Suntour XCM fork lockout is working properly and providing the desired suspension control.
It is recommended to consult a professional bike mechanic or refer to the manufacturer’s documentation for specific instructions on replacing the Suntour XCM fork lockout, as the process may vary depending on the model and year of your fork.
Why would you want to replace it?
There could be several reasons why you would want to replace your Suntour XCM fork lockout. Here are a few possible scenarios:
1. Malfunctioning lockout: Over time, the lockout mechanism of your fork may become worn out or damaged, causing it to not function properly. This can be frustrating, especially if you frequently ride on rough terrains that require a locked fork for better control.
2. Upgrade: The Suntour XCM fork lockout may not meet your specific needs or preferences. If you are looking for better performance, adjustability, or compatibility with other components, you may consider replacing it with a different lockout system that better suits your requirements.

Wrench
In order to replace the Suntour XCM fork lockout, you will need a few tools, including a wrench. The wrench will be used to loosen and tighten the bolts that hold the fork lockout in place.
When choosing a wrench, it is important to select one that is the correct size for the bolts on your fork lockout. Using the wrong size wrench can cause damage to the bolts or strip them, making it difficult to remove or tighten them properly.
It is recommended to use a metric wrench set, as most bike components use metric measurements. A set with a variety of sizes will ensure you have the right wrench for the job. Additionally, it can be helpful to have a wrench with a long handle for more leverage when loosening tight bolts.
When using the wrench, make sure to position it securely on the bolt, applying steady pressure in the direction you need to turn. Avoid using excessive force, as this can cause the wrench to slip and potentially injure yourself or damage the bike.
After loosening the bolts with the wrench, you can remove the old Suntour XCM fork lockout and replace it with the new one. Once the new lockout is in place, use the wrench to tighten the bolts securely, ensuring that there is no play or movement in the lockout when it is engaged.
Remember to always use the wrench properly and safely. If you are unsure about using the wrench or replacing the fork lockout, it is recommended to seek assistance from a professional bike mechanic.
Phillips screwdriver
A Phillips screwdriver is a must-have tool for replacing a Suntour XCM fork lockout. This type of screwdriver features a cross-shaped tip that fits into the corresponding cross-shaped slots on Phillips screws. The screwdriver’s tip is tapered to fit snugly into the screw head, allowing for maximum torque and preventing slippage during use.
To replace a Suntour XCM fork lockout, you will need to use a Phillips screwdriver to remove the screws holding the lockout mechanism in place. The screwdriver’s tip should fit securely into the screw heads, allowing you to turn and remove the screws easily.
When using a Phillips screwdriver, it is important to apply even pressure and keep the screwdriver straight. This will prevent the screws from getting stripped or damaged during removal. Additionally, make sure to choose a screwdriver that is the correct size for the screws you are working with to ensure a proper fit.
Having a quality Phillips screwdriver as part of your tool kit will make replacing a Suntour XCM fork lockout a breeze. Whether you are an experienced DIYer or a beginner, investing in a reliable Phillips screwdriver will save you time and frustration during the replacement process.
