Bike Maintenance Rear Derailleur

To fix a rear derailleur, first check to see if it is bent. If it is, use a derailleur hanger alignment tool to straighten it. If the derailleur is not bent, check to see if the limit screws need to be adjusted.

One day, a man was out riding his bike when he heard a noise coming from the rear derailleur. He stopped to investigate and saw that the chain had come off and was hanging loosely. He didn’t have a chain tool with him, so he had to improvise. He took a rock and hammer and was able to get the chain back on. He was then able to finish his ride. This man’s story is inspirational because it shows that with a little creativity, you can overcome any obstacle.

If you ride your bike frequently, it’s important to maintain your rear derailleur. A rear derailleur helps move the chain from one cog to another on the rear cassette. By keeping your rear derailleur clean and properly adjusted, you’ll ensure that your bike shifts smoothly.

Here are some basic steps for maintaining a rear derailleur on a bike:

1. Clean the derailleur regularly. Debris can build up on the derailleur and cause it to function poorly. Use a clean cloth to wipe away any dirt or grime.

2. Lubricate the derailleur. A dry derailleur can cause shifting problems. Apply a few drops of bike chain lubricant to the derailleur.

3. Adjust the derailleur. If your bike’s shifting is erratic, it could be due to an improperly adjusted derailleur. Use a hex wrench to turn the adjustment screws until the shifting is smooth.

By following these simple steps, you can keep your rear derailleur in good condition and ensure that your bike shifts smoothly.
