Mountain bikes are designed for rough terrain and challenging trails, so it’s not uncommon for riders to encounter problems with their bikes. Rear wheel problems are especially common, which means knowing how to put the rear wheel back on a mountain bike is a crucial skill for any rider. Whether you’re out on the trail or in your garage, being able to quickly and efficiently fix your bike will keep you safe and prevent any delays in your ride.
Fortunately, putting the rear wheel back on a mountain bike is a relatively simple process. With a few tools and a little bit of know-how, you can have your bike up and running again in no time. In this article, we’ll guide you through the steps you need to follow to put the rear wheel back on your mountain bike, so you can get back to riding with confidence.
Removing the Rear Wheel
Removing the rear wheel from a mountain bike is an essential task that every cyclist should learn. It is usually required when replacing the tire, repairing the rim, or maintaining the bike’s drivetrain. To remove the rear wheel, the first step is to flip the bike over or put it on a bike stand to allow access to the rear axle.
Next, shift the bike into the smallest rear cog before releasing the brakes. Most mountain bikes come with disc brakes that usually require you to unscrew the brake caliper before releasing the wheel. Once the brake is loose, you can proceed to detach the rear derailleur from the chain by shifting it to the smallest cog and unscrewing it. With the derailleur removed, release the nut securing the wheel, gently slide it out, and voila! The rear wheel is out, and you can get on with your maintenance tasks.

Inspecting the Rear Wheel and Axle
Before you put the rear wheel back on your mountain bike, it is important to inspect the wheel and axle for any signs of damage or wear. Start by checking the axle to make sure that it is straight and free from any bends or twists. If you notice any damage, it is best to replace the axle before reinstalling the wheel. Next, inspect the wheel itself to ensure there are no broken spokes or bends in the rim. If any damage is present, it may be necessary to replace the wheel altogether.
It is also important to check the condition of the bearings and the hub. You can do this by spinning the wheel and listening for any unusual sounds or feeling any resistance or wobbling. If you notice any of these issues, you may need to replace the bearings or hub. By taking the time to inspect the rear wheel and axle before installing it back on your mountain bike, you can avoid potential issues and ensure that your ride is safe and smooth.
Aligning the Rear Gears and Derailleur
Aligning the Rear Gears and Derailleur is an essential step when putting the rear wheel back on a mountain bike. If the gears and derailleur are not aligned correctly, shifting becomes challenging, leading to poor performance and even damage to the bike’s chain and cogs.
To align the rear gears and derailleur, start by shifting the chain to the smallest cog on the rear wheel. Then, loosen the pinch bolt on the derailleur and manually align the jockey wheel with the smallest cog. After alignment, re-tighten the pinch bolt while ensuring the chain’s tension is correct. Finally, shift through the gears, ensuring they engage correctly and adjust the cable tension if necessary. Proper alignment of the rear gears and derailleur is crucial to enjoy a smooth and efficient ride on your mountain bike.

Reattaching the Rear Wheel to the Bike Frame
With the rear axle now in place, it’s time to reattach the wheel to the bike frame. Begin by lifting the rear wheel up and into the dropouts on the bike frame. Make sure the wheel is straight by checking for equal spacing on both sides of the bike frame. Once the wheel is in place, hand-tighten the quick release skewer, making sure the lever is on the non-drive side of the bike.
Now, you’ll need to tighten the quick release skewer. Flip the lever so it’s parallel to the ground and begin tightening the nut on the opposite side. As you tighten, check the wheel spacing again to ensure it’s straight. Don’t overtighten the skewer, as this can damage the frame or wheel hub. Close the lever and give it a gentle tug. If the wheel moves, the skewer isn’t tight enough – repeat the tightening process. Once you’re satisfied with the tightness, spin the wheel to make sure it rotates smoothly without any rubbing or grinding sounds. With that, you’re finished – you’ve successfully put the rear wheel back on your mountain bike.
Adjusting the Chain Tension
After the wheel is back in place, it’s time to adjust the chain tension. If the chain is too loose, it can slip during gear shifts and cause damage to the bike’s components. On the other hand, if it’s too tight, it can put unnecessary strain on the chain and wear it down faster.
To adjust the chain tension, start by shifting to the smallest cog on the rear wheel and the smallest chainring on the front derailleur. Loosen the rear axle nuts slightly and push the wheel forward until the chain is at the desired tension. Then, tighten the axle nuts back up while ensuring the wheel is centered in the frame. Finally, check the chain tension again in different gears to make sure it’s not too loose or too tight. It may take a few adjustments to get it just right, but it’s worth the effort to ensure the smooth functioning of the bike.
Testing the Rear Wheel
Once you have put the rear wheel back on the mountain bike, it’s crucial to test it thoroughly to ensure it’s safe to ride. Start by giving the wheel a spin to check if it’s running smoothly and not wobbling. If you notice any issues, such as a bent rim or loose spokes, address them immediately.
Next, give the bike a quick bounce up and down while holding onto the handlebars to see if the wheel stays in place. Make sure the wheel is secured tightly in place, and there is no play in the axle. Finally, take the bike for a test ride on a flat surface to see how it handles. If there are any strange noises or vibrations during the ride, stop and check the wheel again before continuing. It’s crucial to take the time to test the rear wheel thoroughly to ensure your safety and prevent any further damage to the bike.

Tips for Preventing Rear Wheel Issues
Maintaining a constant check on your rear wheel can help you prevent unwanted issues. Here are some tips that can ensure the longevity of your rear wheel:
1. Keep your bike clean: Regular cleaning can help you detect any potential issues. Dirt and grime buildup around the rear wheel can cause it to wear out faster and can also lead to a higher risk of rusting.
2. Proper tire pressure: Keep your tire inflated to the recommended pressure listed on the tire to prevent any damage to the wheel caused by an underinflated tire.
3. Check for broken or loose spokes: Loose or broken spokes can cause the wheel to go out of alignment, which can lead to issues while riding.
By following these simple tips, you can ensure that the rear wheel of your mountain bike stays in top shape and provides you with smooth and uninterrupted rides.
Final Thoughts
Putting the rear wheel back on a mountain bike can be a daunting task, especially if you are new to the sport. However, with the right tools and a bit of patience, you can easily reattach your tire and hit the trails in no time.
Remember to properly align the wheel with the derailleur and axle before tightening the nuts or quick-release lever. Make sure that the disc rotor is positioned correctly and the chain is run through the derailleur. Take the time to check the tire pressure and inspect the brakes before taking off. And if at any point you feel stuck or unsure, seek the help of a professional bike mechanic to ensure your safety and the longevity of your bike. Happy riding!
