The SRAM PC-1170 [paid link] chain is a high-performance component designed for use in road bike drivetrains, offering reliability, durability, and smooth shifting. However, improper installation, maintenance, or adjustment can lead to significant performance issues, including poor shifting, premature wear, and even catastrophic drivetrain failure. In this guide, we will highlight the most common mistakes cyclists make when dealing with the SRAM PC-1170 [paid link] chain and provide the necessary steps to avoid these costly errors.

1. Incorrect Chain Length

One of the most common mistakes when installing the SRAM PC-1170 chain is not getting the chain length correct. If the chain is too short, it can lead to overstretched derailleur hangers, excessive wear on the cogs, or even broken chains under high load. Conversely, if the chain is too long, it may result in poor shifting performance and excess slack, leading to chain drops or skipping gears.

How to Avoid:

  • Ensure the chain is sized according to your bike’s drivetrain. You can calculate the proper length by wrapping the chain around the largest chainring and the largest cog, then adding two full links.
  • Use the “big-big” method, where you shift to the largest chainring and the largest cog, then remove the chain, measuring the length with a chain tool.
  • Always double-check your measurements before cutting the chain.

2. Not Using the Correct Chain Tool

The SRAM PC-1170 chain uses a unique design that requires a precise chain tool for installation and adjustments. Using a cheap or incorrect tool can damage the chain or make it difficult to reassemble. Many riders underestimate the importance of using a high-quality chain tool that is compatible with 11-speed chains.

How to Avoid:

  • Invest in a good chain tool specifically designed for 11-speed chains. Look for tools that are recommended by SRAM or other reputable cycling brands.
  • If removing links, be sure to follow the tool’s instructions carefully to avoid damaging the chain pins or rivets.

3. Incorrect Installation of Quick-Link

The SRAM PC-1170 uses a PowerLock quick-link for easy and tool-free installation and removal of the chain. While quick-links provide convenience, incorrect installation can lead to poor shifting performance or the link coming undone mid-ride.

How to Avoid:

  • Ensure the quick-link is oriented correctly before installation. The link should snap together with a consistent, firm engagement. Check that the link is securely locked in place by tugging on the chain before riding.
  • Always inspect the quick-link for wear or damage before installation and replace it if necessary.

4. Poor Lubrication and Cleaning Habits

A frequently overlooked mistake is neglecting proper lubrication and cleaning of the SRAM PC-1170 chain. Without regular cleaning and lubrication, dirt, grime, and moisture can accumulate, leading to premature wear, rust, and suboptimal performance. This can also cause excessive friction, making your drivetrain less efficient and your shifting sluggish.

How to Avoid:

  • Clean the chain regularly with a mild degreaser, focusing on areas where dirt and debris accumulate.
  • Lubricate the chain after cleaning, ensuring you apply the right type of lubricant based on your riding conditions (wet or dry lube [paid link]).
  • Avoid over-lubing the chain, as excess lube attracts dirt, which can cause more harm than good.

5. Ignoring Compatibility with Other Drivetrain Components

The SRAM PC-1170 chain is designed to work seamlessly with SRAM 11-speed drivetrains. However, some riders make the mistake of pairing it with incompatible components from other brands or older SRAM models. This can lead to poor shifting performance, chain wear, and even drivetrain damage.

How to Avoid:

  • Always ensure the SRAM PC-1170 chain is compatible with the rest of your drivetrain, especially the cassette, chainrings, and derailleur.
  • If you are mixing and matching components, double-check the compatibility recommendations from SRAM or consult with a professional mechanic.

6. Failing to Check for Wear Regularly

Chains wear over time, and the SRAM PC-1170 is no exception. A common mistake riders make is failing to check for chain wear regularly. A worn chain can cause poor shifting, excessive wear on the cassette and chainrings, and potentially lead to a broken chain while riding.

How to Avoid:

  • Use a chain checker tool to measure wear and stretch. Most tools will give you a clear indication of when the chain needs to be replaced.
  • As a general rule, replace your chain every 2,000 to 3,000 miles, depending on your riding conditions and maintenance practices.
  • Don’t wait until the chain is completely worn out. Replacing it at the right time can save you money by prolonging the lifespan of your cassette and chainrings.

7. Incorrectly Tensioning the Chain

When setting up or replacing the SRAM PC-1170 chain, improper tension can lead to poor shifting performance and even chain drops. Too much tension can cause excessive friction, while too little tension can result in slack that increases the risk of the chain slipping off.

How to Avoid:

  • After installing the chain, check the tension by shifting through all gears. The chain should sit comfortably on the cassette without any noticeable slack.
  • Use the derailleur’s B-tension screw to adjust the distance between the derailleur pulley and the cassette, ensuring smooth shifting and proper chain tension.

8. Overlooking the Need for Regular Maintenance

A common mistake that cyclists make is assuming that their chain will perform well without regular maintenance. Regular upkeep of the SRAM PC-1170 chain, including cleaning, lubrication, and periodic checks for wear, is essential for maintaining optimal performance and avoiding costly replacements.

How to Avoid:

  • Set a regular maintenance schedule, cleaning and lubricating the chain after every few rides or after exposure to harsh conditions like rain or mud.
  • Check for chain wear and stretch every few hundred miles, especially if you’re riding in tough conditions or frequently shifting under heavy load.

9. Skipping Professional Help When Needed

Even the most experienced cyclists can run into issues with chain installation and maintenance. Failing to seek professional help when encountering problems can lead to more significant issues, especially if you are unsure of the cause of a malfunction.

How to Avoid:

  • If you’re uncertain about the installation or maintenance of your SRAM PC-1170 chain, don’t hesitate to take your bike to a professional mechanic.
  • A qualified bike mechanic can ensure proper installation, adjust the chain for optimal performance, and help you avoid costly mistakes.

Conclusion

The SRAM PC-1170 chain is a critical component in your road bike’s drivetrain, and mistakes in its installation or maintenance can lead to costly repairs or replacements. By avoiding the common errors outlined above, such as incorrect chain length, improper lubrication, and failing to check for wear, you can ensure that your SRAM PC-1170 chain performs optimally and lasts as long as possible. Regular maintenance, proper installation, and attention to detail will keep your bike running smoothly and your drivetrain in top condition.
