If you've been cycling for a while, you're probably making one of the biggest maintenance mistakes possible... and the worst part: it's a silent error.
It doesn't break the bike suddenly, but it slowly kills it.
That error is lubricating the chain over all the accumulated dirt.
Yes, it's that simple. That common. That destructive.
Cyclists usually think about degreasing the drivetrain once or twice a month when doing a more thorough cleaning of our bike, but this is a mistake because we allow dirt to accumulate for days, leading to negative effects on the drivetrain.
Why this error is so serious
1. You create a layer that destroys the drivetrain
Dust + old grease + new lubricant = an abrasive paste that prematurely wears out components.
Result:
- Premature wear
- Drivetrains that last half as long
- Shifting that is no longer smooth
2. Your bike becomes slower (literally)
A dirty chain significantly increases friction.
It's like pedaling with a brake slightly engaged.
Real studies show that a dirty chain can make you lose between 3 and 12 free watts. On flat terrain, that's speed; on climbs, it's suffering; and in short, it means falling behind your group.
3. Lubricant loses effectiveness
If you apply oil or wax to a dirty chain:
- Dirt blocks the links
- The lubricant stays on the outside
- The chain remains dry "inside" and dirty outside
Why do almost everyone do it wrong?
Because most people think that lubricating means "putting oil on the chain" and that's it.
And because no one tells you that:
- The chain is cleaned first
- Then it's dried
- And only then is it lubricated
Lubrication is the last step, not the first.
It takes less than 5 minutes and saves you hundreds of euros.
The conclusion
Avoiding the biggest maintenance mistake is as simple as cleaning before lubricating. Dedicating two minutes to this process can save you money, mechanical problems, and performance loss. A clean chain not only lasts longer: it makes you pedal faster, smoother, and with fewer headaches.
