Top Drive Train Maintenance Mistakes (and How to Avoid Them)
Your bike's drive train is its heart, but a few simple mistakes can wear it out faster and hurt performance. Let's dive into the two most common errors and how to fix them.
The WD-40 Trap
Spray lubricants like WD‑40 may seem convenient, but they're not designed for chains. They wash off easily in rain, leaving your chain dry and unprotected. Worse, the spray often coats rims or brake surfaces, reducing stopping power on rim brake bikes.
Over-Lubrication: When More is Less
Even high-quality lube can become a problem if you keep adding more and more. Excess oil turns your chain into a magnet for dirt and dust, creating gritty paste that grinds away metal—exactly like sandpaper.
Proper Chain Maintenance
- Clean: Remove old oil and debris with a chain cleaner or mild degreaser.
- Lubricate: Apply lube generously to each roller, avoiding over-spraying onto brakes or rims.
- Sit & Wipe: Let it penetrate for about 4 hours, then wipe off any excess so only the internal rollers hold lubricant.
By following these steps, you'll extend your drivetrain's life and keep your shifts smooth. Happy riding!
