The SRAM PC-1170 [paid link] chain is a popular choice for road cyclists seeking high performance and reliability. But as with any component, the question arises: can you upgrade your SRAM PC-1170 [paid link] chain? And if so, what are the best practices for ensuring compatibility with your drivetrain? This article will answer these questions and guide you through the process of upgrading the SRAM PC-1170 chain while highlighting key considerations to maintain optimal performance.

Understanding the SRAM PC-1170 Chain

Before considering an upgrade, it’s important to understand the features and specifications of the SRAM PC-1170 chain. The PC-1170 is a 11-speed chain designed to work with SRAM’s road bike drivetrains. It’s constructed with durable materials, designed for efficient power transfer, and optimized for smooth shifting. Its inner link design and hollow pins contribute to a lightweight construction while maintaining strength and longevity.

Is Upgrading the SRAM PC-1170 Chain Necessary?

In many cases, upgrading your chain depends on the condition of the existing one. If the chain is worn out or starting to cause shifting issues, replacing it with a new SRAM PC-1170 or a compatible chain can restore your drivetrain’s performance. However, upgrading doesn’t always mean replacing the entire chain; there are some situations where improving the setup can make a noticeable difference without changing the chain itself.

Here are a few situations where upgrading the SRAM PC-1170 might be beneficial:

  • Frequent Riding: If you’re riding consistently, especially under harsh conditions, the chain will wear faster. Upgrading to a new chain can restore smooth operation and prevent more extensive drivetrain wear.
  • Shifting Performance: If you notice rough shifting or missed gear changes, a new chain can often improve performance.
  • Aesthetic or Weight Considerations: If you want to shave weight or match aesthetics with higher-end components, upgrading the chain can provide a visual and performance upgrade.

Compatibility Considerations

When upgrading or replacing your SRAM PC-1170 chain, ensuring compatibility with your drivetrain is critical. The SRAM PC-1170 is compatible with any 11-speed SRAM road bike groupset, but there are a few key compatibility considerations to keep in mind:

  1. 11-Speed Drivetrain: The PC-1170 chain is specifically designed for 11-speed drivetrains. If your bike uses a 10-speed or 9-speed drivetrain, upgrading to the PC-1170 chain may not be possible without other drivetrain changes.
  2. Cassette and Chainring Compatibility: Ensure that your cassette and chainrings are designed for 11-speed chains. SRAM’s road bike cassettes and chainrings designed for 11-speed drivetrains are fully compatible with the PC-1170 chain. However, mixing 10-speed or 9-speed components with the PC-1170 chain may result in poor performance and rapid wear.
  3. Derailleur and Shifters: Make sure your front and rear derailleurs are rated for 11-speed systems, as using older 9- or 10-speed derailleur components with an 11-speed chain could result in issues like poor shifting performance or the chain skipping off the gears.
  4. Chain Length: When upgrading to a new SRAM PC-1170 chain, it’s essential to adjust the chain length properly. Too long or too short of a chain can lead to inefficiencies and shifting problems. Ensure the chain length is correct by using the correct procedure to size the chain based on your bike’s drivetrain.

Best Practices for Upgrading the SRAM PC-1170 Chain

When upgrading to a new SRAM PC-1170 chain, following these best practices will ensure maximum performance and longevity:

1. Proper Chain Sizing

  • Use a chain checker tool to assess the wear of the existing chain and determine the right length for your new chain.
  • If replacing a worn chain, it’s critical to match the length of the new chain to the old one for optimal performance. Measure the chain length with the chain installed, following the manufacturer’s recommended procedure.
  • For a new setup, use a chain sizing guide to ensure proper length.

2. Chain Installation

  • Install the SRAM PC-1170 chain using a chain tool. This will ensure the chain is properly connected, with no links overtightened or misaligned.
  • Ensure the chain is routed correctly through the front and rear derailleur for smooth shifting performance.

3. Lubrication and Cleaning

  • Always lubricate the chain before using it to ensure smooth movement and protection against dirt, moisture, and wear.
  • Regular cleaning is essential to remove dirt and debris, which can affect chain performance. Use a degreaser to clean the chain and reapply lubrication to keep it functioning smoothly.

4. Regular Maintenance

  • Regularly inspect the chain for wear, stretching, and damage. An overly worn chain can cause poor shifting and excessive wear on other drivetrain components.
  • If your drivetrain components are showing signs of excessive wear, it’s often best to replace the chain and cassette together, as pairing an old cassette with a new chain can result in poor performance.

5. Chainring Compatibility

  • Check the condition of your chainrings. If you are upgrading to a new chain, ensure your chainrings are in good condition and properly aligned. Worn chainrings can cause poor chain engagement, resulting in skipped shifts or a noisy drivetrain.

Conclusion

Upgrading the SRAM PC-1170 chain is a straightforward process, but it requires careful consideration of compatibility and performance factors. Ensure your entire drivetrain is compatible with the 11-speed chain, and always follow best practices for installation, sizing, and maintenance to maximize your upgrade’s effectiveness. By following these guidelines, you can improve your bike’s shifting performance, prolong the life of your drivetrain, and enhance your overall cycling experience.
