How to Change a Rear Hub on a Mountain Bike
Changing a rear hub on a mountain bike can be a daunting task for many cyclists, but with the right tools and a bit of patience, it can be done relatively easily. Whether you’re dealing with a worn-out hub or a mechanical issue, knowing how to change a rear hub is a valuable skill for any mountain biker. In this article, we’ll guide you through the process step by step.
Step 1: Gather Your Tools
Before you begin, make sure you have the necessary tools for the job. You’ll need a hex wrench, a socket set, a chain whip, a screwdriver, and a pair of pliers. If you’re dealing with a quick-release hub, you’ll also need a quick-release lever.
Step 2: Remove the Wheel
Start by removing the wheel from the bike. If you have a quick-release hub, simply unscrew the lever and pull the wheel out. If you have a thru-axle hub, you’ll need to remove the nuts holding the axle in place. Once the wheel is off, set it aside.
Step 3: Remove the Rear Derailleur
If you have a rear derailleur, remove it from the bike. This will give you better access to the hub. Depending on your bike’s design, you may need to remove the derailleur hanger or simply release the derailleur from the frame.
Step 4: Remove the Freehub Body
Locate the freehub body on the rear hub. This is the part that holds the cassette and is usually held in place by a couple of bolts. Use the appropriate socket to remove these bolts and carefully pull the freehub body off the hub.
Step 5: Remove the Cassette
With the freehub body removed, you should be able to slide the cassette off the hub. If it’s stuck, use a chain whip to help loosen it. Once the cassette is off, set it aside.
Step 6: Remove the Hub
Now it’s time to remove the actual hub. This can vary depending on the type of hub you have. Some hubs are held in place by a single bolt, while others may require you to remove the hub shell. Use the appropriate tools to remove the hub from the frame.
Step 7: Install the New Hub
Take your new hub and install it in the frame. If it’s a quick-release hub, simply push it into place and secure the lever. If it’s a thru-axle hub, thread the axle through the hub and secure it with the nuts.
Step 8: Reinstall the Cassette and Freehub Body
Slide the cassette back onto the hub and replace the freehub body. Secure the bolts with the appropriate socket.
Step 9: Reinstall the Rear Derailleur
If you removed the rear derailleur earlier, now is the time to reinstall it. Make sure it’s properly aligned and secured.
Step 10: Reinstall the Wheel
Finally, reinstall the wheel onto the bike. If you have a quick-release hub, simply push it into place and secure the lever. If you have a thru-axle hub, make sure the axle is properly threaded and secure the nuts.
Now you’ve successfully changed the rear hub on your mountain bike. With a bit of practice, you’ll be able to do this task with ease.
