How do I adjust the rear derailleur on my bicycle?
Adjusting the rear derailleur on your bicycle can seem daunting at first, but with a bit of patience and the right guidance, you can master this essential skill. A properly adjusted rear derailleur ensures smooth gear changes and improves your overall riding experience. Let’s dive into the process step-by-step, exploring the tools youll need, the adjustments youll make, and tips for troubleshooting common issues.
Understanding the Rear Derailleur
Before you begin with adjustments, its crucial to understand the function of the rear derailleur. This component moves the chain between different gears on the rear cassette in response to your gear shifts. When you pull the gear lever, a cable connected to the derailleur is tightened or loosened, causing the derailleur to shift the chain to the desired gear. Misalignment or improper tension can lead to skipping gears, noise, and inefficient cycling.
Tools You Will Need
To adjust your rear derailleur, you will need a few basic tools:
1. Screwdriver: A small Phillips-head screwdriver will be helpful for adjusting limit screws.
2. Allen Wrench: This is necessary for tightening or loosening the derailleur and cable.
3. Bike Stand: A bike stand or a wall will help keep your bike stable while you work.

Step 1: Setting the Limit Screws
Start by locating the limit screws on the rear derailleur. There are typically two screws labeled “H” for high gear (smallest cog) and “L” for low gear (largest cog). These screws control how far the derailleur can move in either direction.
1. High Limit Screw (H): Shift to the smallest rear cog. Adjust the “H” screw until the derailleur is aligned with the cog. If the chain is rubbing against the derailleur, turn the screw clockwise to limit its movement.
2. Low Limit Screw (L): Shift to the largest rear cog. Adjust the “L” screw for alignment. Again, if the chain is making contact, turn the screw clockwise to restrict movement.

Step 2: Adjusting the Cable Tension
Once the limit screws are set, focus on the cable tension. If the cable is too loose, your derailleur won’t shift properly. Conversely, if it’s too tight, it can cause the derailleur to shift unexpectedly.
1. To Adjust Cable Tension: Locate the barrel adjuster on the derailleur or near the handlebars. Turn the barrel adjuster counterclockwise to increase tension or clockwise to decrease it. Shift through the gears to check that the chain moves smoothly across the cassette. A well-tuned derailleur will shift quickly and accurately without hesitation.
Step 3: Fine-Tuning the Derailleur
With the limit screws and cable tension adjusted, it’s time to fine-tune the derailleur. Shift through all the gears and pay attention to how the chain moves. If you notice any skipping or hesitations, make small adjustments using the barrel adjuster until the shifting feels smooth.
Troubleshooting Common Issues
Even after making these adjustments, you may encounter issues. Here are a few common problems and how to address them:
– Skipping Gears: If the chain skips over the cogs, check the cable tension. Too loose cable tension is often the culprit.
– Chain Rub: If the chain rubs against the derailleur, the limit screws may need adjusting.
– Stuck in Gear: If the derailleur won’t shift at all, the cable may be frayed or stuck. Inspect the cable for wear and replace it if necessary.
