It is responsible for moving the bicycle chain to different gears on the cassette, which allows the rider to the resistance and speed of the bike. Keeping the rear derailleur of your bike in good working condition is important to ensure that you enjoy smooth and efficient shifting. If you want to learn how to adjust the rear derailleur of your bicycle, then read on.

Step 1: Check the Alignment

The first thing that you need to check before adjusting the rear derailleur is the alignment of the derailleur hanger. The derailleur hanger is the part of the bike where the derailleur is attached. If the derailleur hanger is bent or misaligned, then the rear derailleur will not function properly. Use a derailleur alignment gauge to check the alignment of the derailleur hanger. If you find that the derailleur hanger is out of alignment, then you may need to take it to a bike shop to have it repaired.

Step 2: Shift the Gears

Shift the bike to the smallest gear on the cassette and to the largest chainring on the crankset. This will give you access to the rear derailleur adjustment barrel, which is located on the derailleur where the cable enters the derailleur body.

Step 3: Increase Cable Tension

If the chain skips or hesitates when you try to shift to a larger gear, then you need to increase the cable tension. Turn the adjustment barrel clockwise to tighten the cable. Shift the gears up and down to check if the shifting has improved. If not, then turn the adjustment barrel another quarter turn and test again. Continue until the shifting is smooth.

Step 4: Decrease Cable Tension

If the chain doesn’t shift smoothly to a smaller gear or drags when changing gears, then you should decrease the cable tension. Turn the adjustment barrel counterclockwise to loosen the cable. Shift the gears up and down to check if the shifting has improved. If not, then turn the adjustment barrel another quarter turn and test again. Continue until the shifting is smooth.

Step 5: Check the High and Low Limits

After adjusting the cable tension, it’s important to check the high and low limits of the derailleur. The high and low limits are two adjustment screws located on the rear derailleur. The high limit screw is used to adjust the derailleur to the smallest gear on the cassette, while the low limit screw is used to adjust the derailleur to the largest gear on the cassette. Use a screwdriver to adjust the screws as needed until the derailleur aligns perfectly with the gears.

Step 6: Take a Test Ride

After you have made all the necessary adjustments, take your bike for a test ride. Check if the shifting is smooth and the chain doesn’t slip or hesitate when changing gears. Make any further adjustments as necessary.

In conclusion, adjusting the rear derailleur of your bike is not very difficult, but it takes time and patience. Always make sure to check the alignment of the derailleur hanger, adjust the cable tension, and check the high and low limits before taking your bike for a test ride. With these steps, you’ll be able to enjoy smooth and efficient shifting on your bike.
