How to Put a Derailleur on a Mountain Bike
Biking enthusiasts often seek to enhance their mountain biking experience by upgrading their gear. One of the most common upgrades is installing a new derailleur. A derailleur is a crucial component that allows you to shift gears smoothly and efficiently. In this article, we will guide you through the process of how to put a derailleur on a mountain bike.
Step 1: Gather the Necessary Tools and Materials
Before you begin, make sure you have the following tools and materials:
– New derailleur
– Chain tool
– Screwdriver
– Allen wrenches
– Grease
– Chain lube
Step 2: Remove the Old Derailleur
Start by removing the old derailleur from your mountain bike. Use the chain tool to remove the chain from the derailleur. Once the chain is off, use the screwdriver to remove the bolts holding the derailleur in place. Be sure to keep track of the bolts and washers, as you will need them for the new derailleur.
Step 3: Install the New Derailleur
Place the new derailleur in the same position as the old one. Thread the bolts through the derailleur and the frame, and tighten them with the Allen wrench. Make sure the derailleur is securely mounted and aligned with the chainrings.
Step 4: Adjust the Derailleur
To ensure smooth gear shifting, you need to adjust the derailleur. First, align the derailleur with the smallest chainring. Then, adjust the limit screws on the derailleur to set the upper and lower limits of the gear range. This will prevent the chain from slipping off the chainrings when shifting gears.
Step 5: Install the Chain
Use the chain tool to remove the old chain and install the new one. Make sure the chain is properly tensioned and aligned with the derailleur and chainrings. Apply chain lube to the chain to prevent rust and wear.
Step 6: Test the Derailleur
After installing the derailleur and chain, take your mountain bike for a test ride. Check the gear shifting by shifting through the entire range of gears. Make sure the derailleur shifts smoothly and that the chain stays on the chainrings without slipping.
Step 7: Clean and Lubricate
Once you are satisfied with the derailleur’s performance, clean the derailleur and the chain with soap and water. Apply grease to the derailleur pivot points and chain to ensure smooth operation and extend the life of your components.
Conclusion
Installing a derailleur on a mountain bike may seem daunting at first, but with the right tools and a bit of patience, it can be a straightforward process. By following these steps, you can enjoy smooth gear shifting and enhance your mountain biking experience.
