A useful drivetrain routine has four parts: remove contamination, lubricate correctly, measure chain wear, and investigate changes in shifting or sound. Cleaning without measuring wear—and lubricating without cleaning—misses half the job.
After ordinary dry rides
Wipe the chain with a clean rag while turning the cranks backward. Check for unusual noise, stiff links, or debris around derailleur pulleys. The chain exterior should not remain wet with lubricant.
After wet or muddy rides
Rinse or clean according to component and cleaner instructions. Avoid high-pressure water near bearings, seals, motors, and suspension. Brush dirt from chainrings, cassette spaces, and pulley wheels without forcing debris deeper into components.
Dry the drivetrain before applying the correct lubricant. Keep all products away from brakes.
Monthly or after heavy use
- Measure the chain using a tool compatible with your drivetrain.
- Inspect chainring and cassette teeth for damage rather than diagnosing wear by shape alone.
- Check that derailleur pulleys turn freely and are not packed with debris.
- Shift through the gears on a stand or during a cautious low-load check.
- Look for damaged cable housing, a bent hanger, or loose components.
Skipping under load, a chain that rides over teeth, or a visibly damaged link needs prompt assessment. See when to replace a chain and chain skipping under load.
