The SRAM Rival 1 (11-speed) is a high-performance drivetrain component designed for smooth shifting and reliable performance. However, like any mechanical system, the derailleur cables on your Rival 1 may wear out over time and need to be replaced. Replacing the derailleur cables is an essential part of bike maintenance that ensures precise shifting and prevents shifting issues that can arise from frayed or damaged cables. This guide will walk you through the process of replacing derailleur cables on your SRAM Rival 1 (11-speed) system.

Tools Required

  • 5mm Allen wrench
  • Cable cutters
  • Torx T25 wrench
  • New derailleur cables (suitable for 11-speed drivetrains)
  • Cable housing (if necessary)
  • Lubricant (optional, but recommended)
  • End caps for cable housing
  • 1.5mm or 2mm Allen wrench for barrel adjusters (depending on setup)

Preparing for the Replacement

Before you begin the replacement process, ensure you have the necessary tools and replacement parts. It’s also important to note whether you need to replace just the cable or the cable housing as well. If the housing is cracked or worn, it’s best to replace it to avoid poor shifting performance.

Make sure to position your bike on a workstand or place it in a stable position to make the job easier and safer.

Step-by-Step Guide to Replacing Derailleur Cables for Rival 1 (11-speed)

Step 1: Remove the Old Cable

  1. Shift to the smallest cog: Start by shifting the chain to the smallest cog on your cassette and the smallest chainring. This helps release tension on the cable and makes it easier to remove.
  2. Loosen the derailleur cable anchor bolt: Using a 5mm Allen wrench or a Torx T25 wrench, loosen the anchor bolt on the derailleur. This will free the cable from the derailleur.
  3. Remove the cable from the derailleur: Slide the cable out of the derailleur and set it aside.
  4. Remove the cable from the frame: Follow the path of the cable as it runs through the cable housing and along the frame. If you are only replacing the cable and not the housing, simply pull the old cable out of the housing and prepare the new one for installation. If the housing is also worn, remove it and discard the old housing.

Step 2: Install the New Cable

  1. Lubricate the new cable: Before installing the new cable, apply a small amount of lubricant to the cable to reduce friction and ensure smooth shifting. This step is optional, but it can significantly improve cable life and shifting performance.
  2. Thread the new cable through the frame: Insert the new derailleur cable into the cable housing at the frame entry point, ensuring it follows the same path as the old cable.
  3. Feed the cable through the derailleur: Starting at the derailleur, feed the cable through the jockey wheels and the derailleur’s cable guide. Ensure the cable is correctly aligned with the derailleur’s cable tensioning mechanism.
  4. Attach the cable to the derailleur: Once the cable is positioned correctly, tighten the derailleur anchor bolt to secure the cable in place. Use the 5mm Allen wrench to tighten the bolt, ensuring the cable is under enough tension to allow for smooth shifting but not too tight to cause shifting issues.

Step 3: Adjust the Cable Tension

  1. Check the shifting performance: After securing the cable to the derailleur, check the shifting by moving the shifters through all the gear positions. Start with the largest cog and shift through each one to ensure the derailleur moves smoothly.
  2. Fine-tune the tension: If the derailleur struggles to shift smoothly or doesn’t reach the larger cogs, use the barrel adjuster (located on the derailleur or shifter) to add tension to the cable. If the derailleur is overshooting or shifting sluggishly, reduce the tension.
  3. Test and verify: After fine-tuning, re-test all the gears to ensure smooth and precise shifting. You may need to make a few adjustments, so don’t hesitate to fine-tune the tension until the system operates optimally.

Step 4: Install New Cable Housing (If Necessary)

If you found that your old cable housing was cracked or damaged, it’s a good idea to replace it.

  1. Cut the new housing: Measure and cut the new cable housing to the correct length using cable cutters. Ensure the housing is slightly longer than the previous housing to avoid unnecessary tension.
  2. Install the new housing: Slide the new housing into the frame’s cable routing channels. Be sure to use new end caps to prevent fraying and protect the cable from dirt and moisture.
  3. Test the cable movement: After installing the new housing, move the derailleur through the gears to verify that the cable moves smoothly through the housing.

Step 5: Final Adjustments and Check

  1. Check the overall shifting: After completing the installation and adjustments, double-check that all the gears shift smoothly and without hesitation.
  2. Test the bike under load: To ensure proper functionality, take the bike for a test ride, shifting through all the gears under various loads. Pay attention to any issues such as skipped gears, chain rub, or delayed shifting.
  3. Tighten all bolts: Before finishing, make sure all bolts, including the derailleur anchor bolt, are properly tightened to the correct torque specifications.

Troubleshooting Common Issues

  • Skipping Gears or Poor Shifting: This could be a sign of improper cable tension, frayed cables, or dirty derailleur components. Recheck the cable tension and ensure the derailleur is clean and lubricated.
  • Shifting Sticking or Jamming: If the cable sticks in the housing, inspect for damaged or clogged housing. Replacing the housing and lubricating the new cable should fix this issue.
  • Derailleur Not Reaching the Largest Cog: If your derailleur is not shifting into the largest cog, the cable may be too tight, or the derailleur’s limit screws might need adjustment. Back off the cable tension and check the limit screws.

Customization and Optimization for Better Performance

To get the best performance out of your Rival 1 (11-speed) drivetrain, consider these optimizations:

  • Use high-quality cables and housing: Upgrading to high-end, low-friction cables and housing can improve shifting performance and reduce the frequency of maintenance.
  • Lubricate regularly: Regularly lubricate the cables to prevent wear and reduce friction for smoother shifting.
  • Keep the derailleur clean: Periodically clean the derailleur to ensure that dirt and grime don’t build up, which can impair shifting performance.

Conclusion

Replacing the derailleur cables on your SRAM Rival 1 (11-speed) is a relatively straightforward process that can greatly improve your bike’s shifting performance. By following the steps outlined in this guide, you’ll ensure smooth and efficient gear changes, extending the life of your components. Regular maintenance, including replacing cables as needed, will keep your Rival 1 drivetrain in top condition for long rides and intense performance.
