Riding a bike is a fun and healthy activity that many people enjoy, but what happens when you hear an unexpected clicking sound every time you pedal? It can be frustrating and concerning, especially if you’re not sure what’s causing the sound.
A clicking noise while cycling can be caused by a variety of issues, from minor ones like loose bolts to more serious ones like worn-out components.
In this article, BSXInsight will explore the different reasons why your bike clicking when pedaling hard and what you can do to fix the problem.
Why is Your Bike Clicking When Pedaling Hard?
1. Hard pedaling
When you’re pedaling hard, you’re putting a lot of stress on your bike’s drivetrain, which can cause clicking sounds.
One of the most common reasons for this is a loose chain. If your chain is loose, it can create a clicking sound when it bounces against the gears or chainrings.
2. Inspect the derailleur pulleys
Another common cause of clicking sounds when pedaling hard is a problem with your derailleur pulleys.
The pulleys are the small wheels that guide your chain between the different gears on your cassette. Over time, these pulleys can become dirty or worn, which can cause clicking sounds.
3. Check the Presta valve nuts
If your bike has Presta valves, the clicking sound could be coming from loose valve nuts.
The Presta valve is the thin, elongated valve found on some bike tires, and it has a small nut on the top that holds it in place. If this nut becomes loose, it can cause clicking sounds when pedaling hard.
4. Inspect the cassette cogs
The cassette cogs are the individual gears on your bike’s rear wheel. Over time, these cogs can become worn or damaged, which can cause clicking sounds when pedaling hard.
5. Inspect the pedals and bottom bracket
The pedals and bottom bracket are two areas where clicking sounds can occur when pedaling hard.
The pedals are part of your bike that your feet rest on, and the bottom bracket is the area where the pedals connect to the bike’s frame. Over time, these components can become loose or worn, which can cause clicking sounds.
6. Unsteady brake pads
Unsteady brake pads can also cause clicking sounds when pedaling hard. This is because the pads can bounce against the rim when they’re not properly aligned.
If your bike is making clicking sounds when pedaling hard, the seatpost may be loose. The seatpost is the tube that holds your bike seat in place, and it’s connected to the frame by a bolt.
Over time, this bolt can loosen and cause the seatpost to move around, which can create clicking sounds.
8. Derailleur Hanger
Another potential culprit for clicking sounds when pedaling hard is the derailleur hanger. The derailleur hanger is part of the frame to which the rear derailleur is attached.
If the derailleur hanger is bent or damaged, it can cause the rear derailleur to shift incorrectly and create clicking sounds.
9. Pedals and Shoes
If you’re using clipless pedals, the clicking sound could be coming from your shoes. This is because the cleats on your shoes can become worn or loose over time, which can cause them to rattle against the pedal.
Finally, the clicking sound may be coming from the frame itself. Over time, the frame can develop cracks or other damage that can cause clicking sounds when pedaling hard.
Fixing Other Bike Noises
Fixing squeaky bike brakes
Squeaky brakes can be an annoying and potentially dangerous issue. The most common cause of squeaky brakes is dirty brake pads or rims.
Dirt and grime build-up can cause the brake pads to vibrate against the rim, leading to the high-pitched squeal that you hear.
The first step to fixing squeaky brakes is thoroughly cleaning the brake pads and rims. Use a clean rag and rubbing alcohol or soap and water to remove any dirt or grime build-up. Be sure to dry everything completely.
If cleaning the brake pads and rims doesn’t work, try sanding the brake pads lightly with fine-grit sandpaper to remove any glaze or build-up.
Sand the pads in a circular motion to avoid creating flat spots.
If the noise persists, you may need to adjust the brake pads. Loosen the brake pad holder bolt and move the pads slightly up, down, left, or right to realign them with the rim. Retighten the bolt and test the brakes to see if the noise is gone.
If none of these fixes work, you may need to replace the brake pads or take your bike to a professional bike mechanic.
Fixing rear suspension pivot noises
If you have a full-suspension mountain bike, you may experience rear-suspension pivot noises. These noises can be caused by dirt and debris entering the pivots or wearing bearings.
The first step to fixing rear suspension pivot noises is thoroughly cleaning the pivots. Use a clean rag, soap, and water to remove dirt and grime build-up. Be sure to dry everything completely.
After cleaning the pivots, apply a lubricant or grease to them to ensure smooth movement. If the noise persists, you may need to replace the bearings. To do this, remove the rear wheel and shock, then remove the pivot bolts.
Use a bearing puller to remove the old bearings and insert the new ones. Finally, reassemble the bike, and test the rear suspension to see if the noise is gone.
If you’re uncomfortable replacing the bearings yourself, take your bike to a professional mechanic.
Fixing a creaky seat post
A creaky seat post can be a common annoyance for many cyclists. The most common cause of this noise is the seat post rubbing against the frame.
The first step to fixing a creaky seat post is to clean and lubricate the seat post and the inside of the frame. Use a clean rag and lubricant to do this. Be sure to remove any excess lubricant to avoid attracting dirt and grime.
Next, tighten the seat post clamp to ensure that it is not loose. Be careful not to overtighten the clamp, as this can damage the frame or seat post. If the noise persists, try adding a thin layer of carbon paste to the seat post.
This paste will create a better bond between the seat post and the frame, reducing any movement and, thus, noise.
If the issue still persists, you may need to replace the seat post or take your bike to a professional bike mechanic.
Fixing a squeaky bike crank
A squeaky bike crank can be caused by several factors, including worn bearings, loose chainring bolts, or a dirty chain.
The first step to fixing a squeaky bike crank is to clean the chain and chainring thoroughly.
Use a degreaser and a clean rag to remove any dirt or grime build-up. Be sure to dry everything completely.
If cleaning the chain and chainring doesn’t work, check the bolts to ensure they are tight.
Use a torque wrench to tighten them to the manufacturer’s specifications. If the noise persists, you may need to replace the bottom bracket bearings.
To do this, remove the crank arms and the bottom bracket and the old bearings. Insert the new bearings, reassemble the bike, and test the crank to see if the noise is gone.
If you’re uncomfortable replacing the bottom bracket bearings yourself, take your bike to a professional mechanic.
