As little as possible; less is more when lubricating a bike chain. Apply a small drop to each link, then wipe off the excess.
A bike chain only needs a tiny amount of lubricant to function correctly. Over-lubricating is a common mistake that attracts dirt and grime, ultimately causing more wear and tear on your drivetrain. Here's a breakdown of the proper technique:
- Apply Sparingly: The key is precision. Aim for a single, small drop of oil on each link of the chain as you slowly pedal backwards. A needle-nose applicator is ideal for this.
- Go Around Once: Ensure you've lubricated every link by making one complete rotation of the chain.
- Penetration Time: After applying the lube, backpedal several times to allow the oil to penetrate the rollers of the chain.
- Wipe Off Excess: This is crucial. Use a clean rag to thoroughly wipe away any excess oil from the outside of the chain. Leaving excess lubricant creates a sticky surface that attracts dirt, which grinds away at your chain and other drivetrain components.
- Listen and Repeat: After a ride or two, listen to your chain. If it sounds dry or squeaky, repeat the process, remembering to use only a small amount of oil.
Why "Less is More"?
- Dirt Attraction: Excessive oil acts like a magnet for dirt, grime, and grit from the road. This abrasive mixture accelerates wear on your chain, cassette, and chainrings.
- Inefficiency: A dirty, over-lubricated chain creates more friction, making you work harder.
- Cleanliness: A properly lubed chain will be clean to the touch on the outside, helping to keep your hands and clothing clean.
What kind of oil should I use?
Use a lubricant specifically designed for bicycle chains. These are available in wet, dry, and ceramic formulations, designed for different riding conditions.
In Summary:
The goal is to lubricate the inside of the chain rollers, not to coat the outside of the chain. A little bit of oil, precisely applied and followed by thorough wiping, is the most effective way to keep your chain running smoothly and extending the life of your drivetrain.
