Quick answer: A noisy chain is almost always dry, dirty, rusty, or too loose. Fix order: clean it with a chain cleaner, treat rust with a rust remover, apply chain lube, and if it's still noisy, get the slack adjusted. 9 times out of 10, cleaning and lubing silences it.
The 4 common causes
- Dry chain — no lube means metal-on-metal grinding. Most common.
- Dirty chain — grit acts like sandpaper.
- Rust — stiff, rusted links click and grind.
- Loose/tight chain — wrong slack slaps or strains.
The fix (in order)
Clean with a chain cleaner → treat rust with a rust remover → dry → apply chain lube. Step-by-step in our chain guide. Still noisy? It's a slack or sprocket-wear issue for your mechanic.
Stop it coming back
Re-lube every 500 km and after wet rides. The 3-in-1 drivetrain kit keeps all three fixes on hand.
