How Often to Lube Your Bike Chain

The chain is the most heavily loaded and most often neglected part of your drivetrain. Well lubricated, it runs quiet, saves watts, and can cover several thousand kilometres. Neglected, it eats the cassette and chainrings, and replacing those costs many times more than a bottle of lube. Here's how often to actually lubricate a chain, and how to do it so the lube does its job instead of just collecting dust.

The short answer: how many kilometres?

There's no single number for everyone — the interval depends mainly on weather and the type of lube. The values below are a safe starting point:

This is a guideline, not a fixed rule. The chain tells you itself when it needs lube — you just have to listen and look.

Signs of a dried-out chain

Instead of counting kilometres, learn to recognise the signals. A chain is asking for lube when:

• it squeaks or rustles while pedalling — the most obvious sign,
• the links look dull and rusty instead of lightly shiny,
• running a (gloved) finger along it leaves dry, rusty dust instead of a thin film of oil,
• the derailleur starts shifting less precisely and more loudly.

If you hear squeaking while riding, you're already quite late — that's when drivetrain wear is fastest.

Dry lube or wet lube?

The choice of lube changes the maintenance interval more than anything else.

Dry lube

Light, solvent-based, which evaporates and leaves a waxy film. Collects little dust, keeps the chain clean — but washes out quickly. Ideal for dry weather and the trainer. Needs reapplying more often.

Wet lube

Thick, oily, water-resistant. Lasts a long time even in the rain, but, like a magnet, pulls in dust and grit, forming a grinding paste. In dry conditions it quickly turns the chain into black grime. Good for autumn, winter and long rainy rides.

The most important rule: don't mix lubes without cleaning first. New lube applied over an old layer of grime just seals the grit inside the links.

How to lubricate a chain correctly — step by step

1. Clean it. Wipe the chain with a dry rag, turning the crank backward. If it's heavily soiled, use a degreaser or a chain-cleaning tool and let it dry.
2. Apply lube to each link. One drop on each roller (the inner side of the chain), turning the crank backward through 2–3 full revolutions. Don't pour a whole stream over the top.
3. Let it soak in. Wait — for dry lube, even a few hours, for the solvent to evaporate. That's why it's best to lubricate in the evening before a ride, not right before you head out.
4. Wipe off the excess. Thoroughly wipe the outside of the chain with a dry rag. The lube should work inside the links — excess on the outside just collects dirt.

This last step makes the biggest difference: clean on the outside, oiled on the inside — that's the goal.

What else extends drivetrain life

• Check chain elongation with a wear checker. Replaced on time (usually at 0.5–0.75% elongation), it protects the cassette and chainrings from premature wear.
• After riding in the rain, always wipe down and reapply lube — water washes it out within hours.
• Avoid washing your drivetrain with a pressure washer — we explain why in a separate article on washing your bike with a pressure washer.

Summary

The simplest rule: lubricate before the chain starts squeaking, match the lube to the weather, and always wipe off the excess. Dry lube roughly every 200 km, wet lube every 300–400 km is a good starting point, but the final word belongs to how your drivetrain looks and sounds. Regular, two-minute maintenance is the cheapest way to keep a drivetrain running quiet for thousands of kilometres.
