A bike in good condition is never completely silent. The sound of the chain, the tires on the road, or the hub is all part of the joy of riding.
But when a new click, crack, squeak, or rub suddenly appears, it is better not to just turn up the volume on your headphones.
Some noises indicate a simple adjustment is needed. Others may signal a worn part that risks damaging other components.
Here are 7 bike noises you are better off not ignoring.
1. A "click" with every pedal stroke
Do you hear click… click… click… always at the same point when you pedal?
The first reaction is often to blame the bottom bracket. But the noise could also come from the pedals, the crankset, a chainring, the saddle, or even the seat post.
Sounds transmit very easily through a frame, which sometimes makes their origin difficult to identify.
Tip: try pedaling while standing up for a few seconds. If the noise disappears, look toward the saddle or seat post instead.
2. The chain is noisy in certain gears
A properly adjusted drivetrain should shift gears smoothly.
If the chain starts making noise only on certain cogs, the problem could come from a poorly adjusted derailleur, a cable, a derailleur hanger, or simply wear on the drivetrain.
Don’t let the problem persist for too long.
A misaligned chain can accelerate wear on the cassette and gradually make gear shifting less precise.
3. A rubbing brake disc
Shhh… shhh… shhh…
You are probably familiar with this sound.
A slight rubbing can come from a poorly centered caliper, a slightly warped disc, or an issue with the wheel.
If the noise appears suddenly after removing and reinstalling the wheel, start by checking that it is installed correctly.
If the rubbing persists, a brake adjustment may be necessary.
4. A squeak when you brake
Disc brakes that become very noisy can signal contamination of the pads or the disc, significant wear, or a mounting issue.
And pouring any kind of product on them to make the noise disappear is a very bad idea.
Braking surfaces must remain perfectly clean.
If your brakes start to squeak and the braking power decreases, have them checked quickly.
5. A crackling sound from the handlebars
A noise when you pull on the handlebars, brake hard, or ride standing up deserves special attention.
It can come from the stem, the handlebar, the headset, or incorrect tightening.
You can also check if there is any play in the headset: lock the front brake and gently rock the bike forward and backward.
Do you feel a small movement in the steering?
It is time to take a closer look.
6. A noise coming from a wheel
A small, regular tick-tick can sometimes come from a spoke.
But a wheel can also start producing noises when a spoke loses tension, when a bearing starts to wear out, or when another element has play.
After a significant impact or a long period of gravel riding, also check that the wheel rotates correctly and does not show significant wobbling.
A small wheel issue is generally much simpler to resolve before a spoke breaks in the middle of a ride.
7. A crackling sound that only appears when you push hard
Everything is silent when you ride casually.
Then you tackle a climb, push hard on the pedals, and…
Crack. Crack. Crack.
This type of noise can have many origins: pedals, crank arms, bottom bracket, chainring, drivetrain, or various tightening points.
It is also one of the most difficult noises to diagnose yourself, because it only appears when the bike is under load.
And no, putting lubricant everywhere until the noise disappears is not a diagnostic method.
A new noise? Don’t wait to see if it goes away
A bike that suddenly starts making an unusual noise is usually trying to give you information.
Sometimes, all it takes is cleaning or a small adjustment.
Sometimes, a chain is at the end of its life, a bearing is starting to get tired, or a part needs to be tightened.
In any case, acting early is often simpler and less expensive than waiting for a breakdown.
Routes&Roads bike workshop in Paris 13
Do you have a crackling sound that is impossible to locate? A derailleur that makes noise? A disc that rubs or brakes that squeak?

We can perform diagnosis, maintenance, and repair of your bike, whether it is a gravel bike, a road bike, a city bike, or a mountain bike.
And when you come to the workshop, don’t hesitate to explain when the noise appears: when climbing, when braking, when standing up, in certain gears, or only when you push hard.
These small details can help us tremendously in finding its origin.
A bike can make a lot of noises. Our job is to find the one it shouldn't be making.
