Describing Derailleur Noise to a French Bike Mechanic
Learn French words and sentence patterns to explain derailleur noises, when they happen, and which gears are involved, so a mechanic can diagnose the problem quickly.
By SofiaGetting around · Yapr Learn
When your gears start making strange noises, the hardest part is often explaining exactly what you hear and when it happens. In French, you do not need long sentences: a few precise words plus a clear time marker are enough. This lesson gives you the vocabulary for the derailleur (le dérailleur), the most common noises, and the gear terms you need. You will learn to say what the noise sounds like, when it appears, and which gear you were in, so a mechanic can understand the problem immediately.
By the end, you can…
- name the derailleur and the main gear parts in French.
- describe a noise with a simple verb or onomatopoeia.
- say when the noise happens using a time clause.
- ask a mechanic to check the bike and explain the problem.
Listen once. Try it slowly. Then say it without looking.

Mon dérailleur fait un bruit bizarre.
My derailleur is making a strange noise.
mohn day-rye-urr fay uh brwee bee-zarr
A general opening line. Use it when you are not sure what the noise is yet.
Ça grince quand je passe sur le grand plateau.
It screeches when I shift to the big chainring.
sah granss kahn zhuh pass syr luh grahn plah-toh
Use 'grincer' for a high, scraping or squealing sound. 'Le grand plateau' is the larger front chainring.
Ça saute quand je passe sur le petit pignon.
It skips when I shift to the small sprocket.
sah soht kahn zhuh pass syr luh puh-tee pee-nyohn
Use 'sauter' when the chain jumps or the gear slips. 'Le pignon' is a rear sprocket.
On entend un clic-clic régulier.
You can hear a regular click-click.
ohn ahn-tahn uh kleek-kleek ray-gyoo-lyay
A common onomatopoeia for a rhythmic clicking sound. Use it to describe repeated noise.
Est-ce que vous pouvez regarder le dérailleur arrière ?
Can you look at the rear derailleur?
ess kuh voo poo-vay ruh-gar-day luh day-rye-urr ah-ryair
A polite request. 'Pouvez' is the polite 'vous' form, suitable with shop staff.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
The core pattern is: Ça + noise verb + quand + je + gear action. For example, 'Ça grince quand je passe sur le grand plateau' means 'It screeches when I shift to the big chainring.' You can swap the verb: 'Ça saute' (it skips), 'Ça craque' (it cracks), 'Ça cliquette' (it clicks). You can also swap the gear: 'sur le petit pignon' (on the small sprocket), 'sur le grand pignon' (on the large sprocket), 'sur le petit plateau' (on the small chainring). Keep the sentence short; the mechanic mainly needs the sound and the moment it happens.
When to use it
Use these sentences when the noise is not constant. If it only happens in one gear, say the gear: 'seulement sur le grand plateau' (only on the big chainring). If it happens when you pedal hard, add 'quand j'appuie fort' (when I push hard). If it happens after shifting, say 'juste après avoir changé de vitesse' (just after changing gear). This tells the mechanic whether the problem is in the derailleur adjustment, the chain, or the cassette. Avoid vague words like 'bruit' alone; add the sound verb and the moment.
Listen to each line, then take one part and reply out loud.
Bonjour, j'ai un problème avec mon vélo. Le dérailleur arrière fait un bruit bizarre.
Hello, I have a problem with my bike. The rear derailleur is making a strange noise.bohn-zhoor, zhay uh proh-blem ah-vek mohn vay-loh. luh day-rye-urr ah-ryair fay uh brwee bee-zarrD'accord. Ça fait quel genre de bruit ?
OK. What kind of noise does it make?dah-kor. sah fay kel zhahn-ruh duh brweeÇa grince quand je passe sur le grand plateau, et ça saute parfois sur le petit pignon.
It screeches when I shift to the big chainring, and it sometimes skips on the small sprocket.sah granss kahn zhuh pass syr luh grahn plah-toh, ay sah soht par-fwah syr luh puh-tee pee-nyohnJe vais regarder le dérailleur et la chaîne. Vous pouvez me montrer quand ça arrive ?
I will look at the derailleur and the chain. Can you show me when it happens?zhuh vay ruh-gar-day luh day-rye-urr ay lah shen. voo poo-vay muh mohn-tray kahn sah ah-reevA little context goes a long way
In French bike shops, staff often use informal 'tu' with regular customers, but 'vous' is safer when you do not know them. 'Le dérailleur' is standard in France, Belgium and Switzerland; in Quebec, people also say 'le dérailleur' but may use 'vitesses' more generally. Mechanics appreciate precise sound words and gear names more than long explanations.
One thing to watch for
Saying 'Mon dérailleur est cassé' when you only hear a noise.
Try this instead: 'Cassé' means broken. If the bike still shifts, say 'Il fait un bruit bizarre' or 'Ça grince'. Use 'cassé' only if a part is actually broken, for example: 'La chaîne est cassée.'
Your turn
Try answering out loud before checking a possible answer.
1How do you say 'It screeches when I shift to the big chainring' in French?
Show a sample answer
Ça grince quand je passe sur le grand plateau.
This uses 'grincer' for a screeching sound and 'le grand plateau' for the big front chainring. You could also say 'quand je monte sur le grand plateau' with a similar meaning.
2Which French word means 'rear sprocket' on a bike?
Show a sample answer
Le pignon.
'Le pignon' is a rear sprocket. The whole set is 'la cassette'. 'Le plateau' is the front chainring, so do not mix them up.
3How would you politely ask a mechanic to look at the rear derailleur?
Show a sample answer
Est-ce que vous pouvez regarder le dérailleur arrière ?
This uses the polite 'vous' form 'pouvez'. With a familiar mechanic, you could say 'Tu peux regarder le dérailleur arrière ?'
Name the sound, then say when it happens: 'Ça grince quand je passe sur le grand plateau.' Add the gear if the noise only appears there, and use 'vous' with shop staff.
