Lubing a bike chain means wiping off old grime, applying a drop of lube to each link while turning the pedals backwards, letting it soak in, and wiping off the extra. A clean, lightly lubed chain runs quietly and wears more slowly. Keep lube away from brake surfaces and check the bike maker’s advice.
Things You Will Use
- Chain lube suited to your riding conditions
- Clean rags
- A degreaser and old brush, for a dirty chain
- A bike stand, or someone to lift the back wheel
- Cardboard to shield the floor
Wet or Dry Lube
| Type | Suits | Trade-off |
|---|---|---|
| Dry lube | Dusty, dry weather | Needs reapplying more often |
| Wet lube | Rain and mud | Attracts more dirt, needs more wiping |
The Process
- Lift the rear wheel so the pedals turn freely and you can spin the cranks by hand.
- Hold a rag around the chain and turn the pedals backwards, letting the rag wipe away dirt.
- If the chain is black and gritty, brush on degreaser, wipe off, and let the chain dry completely.
- Place the lube nozzle over the lower run of the chain.
- Turn the pedals slowly backwards and add one small drop to each roller.
- Rotate the cranks a few more turns so lube spreads.
- Wait several minutes. Check the lube label for the recommended time.
- Wrap a clean rag around the chain and run it once more to wipe off excess.
Avoid These Mistakes
- Spraying near brake discs or rim surfaces
- Applying lube on top of thick dirt
- Using too much, which only collects grit
- Dismissing noise; a squeak or a gritty feel means a chain is due for care
Over time a chain stretches. Many riders measure it with a small checker tool and replace it on schedule, using the maker’s guide.
Listen to the chain as you ride. A smooth, quiet drivetrain is a good sign. If it begins to squeak or feel rough, it probably wants attention, and if shifting becomes sloppy even after cleaning, the chain or cassette may be worn. Record the date of each lube so you can see a pattern, and keep the bottle capped and upright so it does not leak or collect grit.
If you ride in different conditions through the year, you may keep two bottles, one for dry days and one for wet spells. Label them clearly, and clean the chain before switching types so the two do not mix and turn gummy.
FAQ
How often should I lube?
Many riders do it after wet rides or every few weeks, depending on use. Follow your bike maker’s suggestions.
Can I use household oil?
Bike-specific lube is formulated for chains. General-purpose oils may attract dirt or wash off.
The Short Version
Wipe, degrease if needed, drip lube on each roller, wait, and wipe again. Keep it off the brakes and choose a lube type that fits your weather.
