The short version

  • If a step feels uncertain, stop and use a qualified bicycle mechanic.
  • Never ride with brakes, steering or wheels that you suspect are unsafe.
  • Use the component manufacturer's instructions for torque settings and model-specific procedures.
01

Before you start

Inspect the chain before cleaning: look for damaged plates, stiff links, heavy corrosion and signs that wear should be measured. Protect disc rotors or rim-braking surfaces and choose a cleaning method and lubricant that the drivetrain maker permits.

  • Use tools that fit the fastener properly
  • Keep small parts in removal order
  • Do not force a seized or cross-threaded component
  • Check the maker's manual for your exact part
02

Check whether lubrication is the remedy

A dry-sounding but otherwise sound chain may need cleaning and lubrication. A stiff link, heavy rust, damaged plates, poor shifting under load or wear beyond the drivetrain maker's limit needs inspection or replacement rather than more oil.

Choose a bicycle chain lubricant for the expected conditions and follow its application instructions. Applying heavily over old grit creates an abrasive paste and leaves lubricant available to fling onto braking surfaces.

Protect disc rotors, rim-braking tracks and pads while working. If lubricant reaches a braking surface, follow the brake or component maker's cleaning and pad-replacement guidance before riding.

Step by step

  1. 1

    Choose a bicycle chain lubricant suited to the conditions.

  2. 2

    Wipe or clean the chain and let it dry.

  3. 3

    Apply a small drop to each roller while turning the cranks backwards.

  4. 4

    Allow time for the lubricant to penetrate.

  5. 5

    Wipe the outside of the chain thoroughly with a clean rag.

Choose wet lube for persistent rain; dry-weather or wax systems need a different product.

04

Checks before riding

Turn the drivetrain slowly, allow the lubricant the stated time to reach the rollers and wipe the chain's exterior until it no longer leaves obvious excess on a clean rag. Check that links articulate freely and that no lubricant has reached a tyre or braking surface.

  • Every link articulates freely
  • Excess lubricant has been wiped from the chain
  • Tyres and braking surfaces remain uncontaminated
  • The drivetrain runs without a new skip or stiff link
05

When to use a bike shop

Lubrication cannot repair a stretched, cracked, twisted or persistently stiff chain. Ask a mechanic to measure drivetrain wear or investigate skipping under load, and follow the brake maker's advice if oil has contaminated pads or another friction surface.
