Replacing derailleur cables is an essential aspect of maintaining your road bike. For cyclists who use the microSHIFT Advent RD-M6195M [paid link] rear derailleur, ensuring that the derailleur cable is in optimal condition will ensure smooth shifting performance and a longer lifespan for your drivetrain. In this guide, we’ll walk you through the process of replacing the derailleur cable for the Advent RD-M6195M.

Tools Required

  • 5mm Allen wrench
  • Cable cutters
  • 3mm Allen wrench
  • Phillips screwdriver
  • New derailleur cable
  • Lubricant or grease (optional)
  • Needle-nose pliers
  • Torque wrench (optional)
  • Bike stand (optional but recommended)

Step-by-Step Guide to Replacing Derailleur Cables for Advent RD-M6195M

1. Preparing the Bike

Before starting the replacement, ensure that your bike is secured in a bike stand. If you don’t have a stand, flipping the bike upside down will also work. It’s important to position the bike so that you can comfortably access the derailleur and cable routing.

2. Remove the Old Derailleur Cable

  • Shift to the Smallest Cog: Begin by shifting your bike to the smallest rear cog. This ensures there is minimal tension on the cable and the derailleur, which will make the process easier.
  • Release the Cable: Using a 5mm Allen wrench, remove the bolt securing the derailleur cable to the derailleur itself. Carefully release the cable from the derailleur by pulling it out through the derailleur arm.
  • Remove the Cable from the Housing: With the cable disconnected from the derailleur, trace it back along the frame and remove it from the cable housing. Use needle-nose pliers if necessary to pull the cable out of tight spots.

3. Inspect and Prepare the New Cable

  • Cut the New Cable to Length: Take the new derailleur cable and cut it to the appropriate length, leaving a bit of extra length to accommodate any adjustments later. Be sure to cut the cable cleanly with cable cutters to avoid frayed ends.
  • Lubricate the Cable (Optional): Apply a small amount of lubricant or grease to the cable. This step is optional but can help reduce friction and ensure smooth operation.

4. Install the New Cable

  • Insert the Cable into the Housing: Insert the new derailleur cable into the housing at the front of the bike, where the cable begins its route to the rear derailleur. Ensure the cable slides smoothly through the housing.
  • Thread the Cable Through the Derailleur: Once the cable reaches the derailleur, thread it through the guide on the derailleur arm, ensuring the cable is properly aligned.
  • Secure the Cable: Using the 5mm Allen wrench, tighten the cable bolt on the derailleur, securing the cable in place. Be sure not to overtighten; just enough to hold the cable firmly in place.

5. Adjust the Tension

  • Test the Tension: Shift the bike into the smallest cog and check the derailleur’s position. The derailleur should be taut but not overly tight. If there is too much slack or the cable is too tight, you’ll need to adjust the tension.
  • Fine-Tune the Cable Tension: Using the barrel adjuster located either at the rear derailleur or shifter, fine-tune the tension. Turning the barrel adjuster clockwise will increase tension, while turning it counterclockwise will release tension. Adjust until you have smooth shifting performance across all gears.

6. Check the Shifting Performance

Once the cable is installed and the tension is adjusted, test the shifting performance by shifting through all the gears. Ensure the derailleur is smoothly moving between cogs without skipping or hesitation. If you notice skipping, further adjust the cable tension until shifting is smooth.

7. Trim the Cable

  • Trim Excess Cable: After confirming the cable is properly tensioned and the derailleur is functioning as expected, use cable cutters to trim any excess cable sticking out from the derailleur.
  • Secure the End: After cutting the cable, use needle-nose pliers to bend the end of the cable inwards or use a cable cap to prevent the cable from fraying and causing injury.

Troubleshooting Common Issues

Even after replacing the derailleur cable, some issues might arise. Here are a few troubleshooting tips to help resolve them:

  • Skipping Gears: If your bike is skipping gears after replacing the cable, it’s often a sign of too much slack or excess tension in the cable. Adjust the barrel adjuster slowly, testing between each adjustment until the skipping stops.
  • Shifting is Slow: Slow or delayed shifting can occur if the cable isn’t lubricated or properly threaded. Make sure the cable moves smoothly through the housing and derailleur.
  • Cable Slippage: If the derailleur cable slips after installation, double-check the tension and ensure that the cable is secured tightly at both ends.

Customization and Optimization for Better Performance

For optimal performance with the microSHIFT Advent RD-M6195M, consider the following customization tips:

  • Upgrade the Cable Housing: To reduce friction and improve the overall shifting performance, consider upgrading your cable housing to a higher-quality material, such as low-friction liners or teflon-coated cables.
  • Use Quality Cables: Ensure that the derailleur cable you choose is of high quality. While it’s tempting to use any cable, using cables specifically designed for your derailleur can provide a noticeable improvement in shifting performance.
  • Adjust the Limit Screws: After replacing the derailleur cable, check and adjust the limit screws to ensure the derailleur doesn’t overshift into the spokes or off the cassette.

Comparing the Advent RD-M6195M with Other Models

When comparing the microSHIFT Advent RD-M6195M with other models like Shimano or SRAM, here are some key differences to consider:

  • Weight: The Advent RD-M6195M is known for its lightweight design, which is an advantage for those who prioritize speed and performance.
  • Compatibility: The Advent RD-M6195M is compatible with 9-speed drivetrains, making it a great option for those using 9-speed cassettes. It’s more limited in compatibility when compared to 10 or 11-speed systems, which offer more gear options.
  • Price: The Advent RD-M6195M is a more budget-friendly option, providing excellent performance for its price point. Higher-end models, like SRAM’s NX or Shimano’s SLX, come with more features but at a higher price.

Understanding Compatibility with Other Drivetrain Components

The microSHIFT Advent RD-M6195M is designed to work with microSHIFT’s 9-speed drivetrains. It features a wide gear range and smooth shifting performance, but compatibility is limited to specific cassettes and shifters. Using the correct shifter for the RD-M6195M will ensure the best performance. While it’s possible to mix components from other brands, it’s important to ensure that the shifter and derailleur are compatible in terms of both speed (9-speed) and cable pull ratio.

By ensuring proper installation, adjustment, and regular maintenance, your Advent RD-M6195M derailleur will provide reliable performance for years to come.
