Your bicycle chain is critical for a smooth, efficient ride.
Regular bike chain maintenance reduces wear and improves shifting performance.
Follow these simple steps to keep your drivetrain running like new.
Tools & Supplies
-
Chain cleaning tool.
-
Drivetrain degreaser.
-
Stiff brush or cassette brush.
-
Clean rags or microfiber cloths.
-
Chain wear indicator tool.
-
Quality chain lubricant (wet or dry lube).
Step 1 — Remove or Use a Chain Tool
If your chain has a quick link, you can remove it for deep cleaning.
If not, use a chain cleaning tool to clean the chain in place.
Both methods work; choose based on convenience and grime level.
Step 2 — Apply Degreaser & Scrub
Spray or apply a drivetrain degreaser onto the chain, cassette, and jockey wheels.
Let the degreaser sit a few minutes to dissolve old oil and grime.
Use a rotating brush or chain-cleaning tool to scrub each link and roller thoroughly.
Step 3 — Rinse & Dry
Rinse the chain with clean water and shake off excess moisture.
Dry the chain completely with a clean rag or compressed air.
Never apply lubricant to a wet chain or you will trap moisture.
Step 4 — Lubricate Correctly
Apply drops of chain lube to each roller while slowly turning the cranks backwards.
Allow the lubricant to penetrate for a few minutes before wiping excess.
Wipe off surplus lube to prevent dirt build-up and reduce wear. NAC's All Weather Lube or High Performance Dry Lube
Chain Tension & Adjustment
Check chain tension on single-speed or hub-gear bikes and adjust if needed.
For derailleur bikes, ensure the derailleur keeps proper chain slack across gears.
Incorrect tension causes shifting problems and increases component wear.
Check Chain Wear
Use a chain wear indicator tool to check chain elongation and wear.
Replace the chain when elongation reaches about 0.5% to 0.75% to protect the cassette.
Timely replacement saves money by preventing excessive wear on chainrings and cassettes.
Regular Inspection
Inspect the chain for rust, tight or bent links, and missing rollers.
Replace damaged links or the full chain if repair is not possible.
Consult a professional mechanic for severe wear or complex drivetrain issues.
Final Tips
Clean and lube your chain every 200–300 km or after muddy rides.
Use wet lube for rainy conditions and dry lube for dusty trails.
Keep a compact chain tool and spare quick link in your Koala Frame Bag or N625 Saddlebag.
Proper chain care improves shifting, reduces drivetrain costs, and makes rides smoother.
