How to Install Rear Derailleur on a Mountain Bike
Installing a rear derailleur on a mountain bike is an essential task for any cyclist looking to maintain or upgrade their bike. The rear derailleur is responsible for shifting the chain between the various gears, allowing for smoother rides and better performance. Whether you’re a beginner or an experienced cyclist, installing a rear derailleur can be a challenging but rewarding process. In this article, we will guide you through the steps to install a rear derailleur on your mountain bike.
1. Gather the Necessary Tools
Before you begin, make sure you have the following tools and materials:
– Rear derailleur
– Chain
– Chain tool
– Grease
– Screwdriver
– Hex wrench
– New cables and housing (if necessary)
2. Remove the Old Rear Derailleur (if applicable)
If you’re replacing an old rear derailleur, start by removing it from the bike. Locate the derailleur hanger on the frame and use the appropriate hex wrench to loosen the bolt that holds the derailleur in place. Once the bolt is loose, carefully remove the derailleur from the bike.
3. Mount the New Rear Derailleur
Position the new rear derailleur on the derailleur hanger. Make sure the derailleur is facing the correct direction and that the pulley cage is aligned with the sprockets. Secure the derailleur to the hanger using the provided bolt and tighten it with the hex wrench.
4. Install the Cables and Housing
If you’re installing new cables and housing, begin by routing the housing through the frame. Thread the cables through the housing and attach the cables to the derailleur and shifter. Make sure the cables are tensioned properly and that there are no kinks or twists in the housing.
5. Adjust the Rear Derailleur
Adjust the rear derailleur to ensure proper shifting. Begin by adjusting the high-limit screw, which determines the highest gear the derailleur can shift to. Loosen the bolt, move the derailleur to the desired position, and then tighten the bolt. Repeat this process for the low-limit screw, which determines the lowest gear the derailleur can shift to.
6. Install the Chain
Attach the chain to the derailleur by threading it through the sprockets. Use the chain tool to remove any excess links, if necessary. Once the chain is properly installed, apply some grease to the chain and the derailleur pulleys.
7. Test the Shifting
After completing the installation, take your mountain bike for a test ride to ensure the shifting is smooth and proper. If you encounter any issues, go back and adjust the derailleur limits or the tension on the cables.
8. Final Touches
Inspect the entire setup, including the cables, housing, and derailleur, for any loose parts or signs of wear. Make any necessary adjustments and ensure everything is functioning correctly.
