The SRAM PC-1170 [paid link] chain is a high-performance 11-speed road bike chain designed for smooth shifting, durability, and optimal drivetrain efficiency. Whether you’re upgrading your chain or replacing a worn-out one, proper installation and maintenance are crucial for peak performance. Incorrect setup can lead to skipping, noisy shifting, and premature wear.

This guide covers everything you need to know about installing, adjusting, and maintaining the SRAM PC-1170 [paid link] chain to keep your drivetrain running smoothly.

Before you begin, gather the following tools:

How to Install the SRAM PC-1170 Chain

Step 1: Measuring and Cutting the Chain

New chains are longer than necessary to fit multiple bike setups. To size it correctly:

  1. Wrap the new chain around the largest front chainring and the largest rear cog, bypassing the derailleur.
  2. Add two full links (one inner and one outer) for proper length.
  3. Use a chain breaker tool to remove excess links.

Pro tip: If replacing an old chain, match the new chain length to the previous one if it was correctly sized.

Step 2: Installing the Chain on the Bike

  1. Route the chain through the rear derailleur jockey wheels while ensuring correct threading through the cage.
  2. Align the PowerLock quick link (SRAM’s tool-free connector) and snap the ends together.
  3. Rotate the crank to place the quick link on the upper section of the chain.
  4. Apply firm pedal pressure to lock the PowerLock in place.

How to Adjust the SRAM PC-1170 Chain for Optimal Performance

Checking Chain Tension and Derailleur Alignment

  1. Shift into the smallest front chainring and smallest rear cog to release chain tension.
  2. Ensure the chain has a slight amount of slack but not excessive droop.
  3. Shift through all gears to verify smooth engagement and proper derailleur alignment.

Fine-Tuning the Chain for Silent Operation

  1. If shifting is noisy or sluggish, check rear derailleur limit screws and adjust as needed.
  2. Use the barrel adjuster to fine-tune cable tension for crisp shifts.
  3. Ensure the cassette and chainring teeth are in good condition—a worn drivetrain can cause chain skipping.

How to Maintain the SRAM PC-1170 Chain

Regular Cleaning to Prevent Wear

Dirt and grime accelerate chain wear. Clean your chain at least every 200-300 miles, or more often in wet conditions.

  1. Use a chain cleaning tool with degreaser for deep cleaning.
  2. Wipe the chain dry and let it sit for a few minutes.
  3. Apply a high-quality lubricant evenly across all links, then wipe off excess oil.

When to Replace the PC-1170 Chain

The SRAM PC-1170 [paid link] chain should be replaced when it reaches 0.5% to 0.75% wear (measured with a chain wear gauge). A worn chain accelerates cassette and chainring wear, leading to costly replacements.

To check wear:

  • Use a chain checker tool—if it falls into the 0.5% gap, replace the chain soon.
  • If it reaches 0.75% wear, immediate replacement is necessary.

Common Issues and Troubleshooting

1. Chain Skipping Under Load

Cause: Chain is stretched or cassette teeth are worn.
Fix: Measure the chain for wear and replace it if necessary. Inspect the cassette for worn teeth and replace if needed.

2. Noisy Shifting Between Gears

Cause: Dirty or dry chain, poor derailleur alignment, or incorrect cable tension.
Fix: Clean and lubricate the chain, check derailleur alignment, and fine-tune cable tension.

3. Chain Drops Off the Chainring

Cause: Worn chainrings, incorrect chain length, or misaligned front derailleur.
Fix: Check chain length, inspect chainrings for wear, and adjust the front derailleur position.

Best Practices to Extend Chain Life

To maximize the lifespan of your SRAM PC-1170 chain, follow these best practices:

  • Clean and lubricate your chain regularly to prevent premature wear.
  • Avoid cross-chaining (e.g., big chainring + big cog or small chainring + small cog).
  • Check chain wear every 500 miles and replace it before it damages the cassette.
  • Store your bike indoors to prevent rust and corrosion.

Final Thoughts

Proper installation, adjustment, and maintenance of the SRAM PC-1170 chain ensure a smoother ride, precise shifting, and a longer-lasting drivetrain. By following these steps, you’ll avoid common issues like chain skipping, premature wear, and noisy shifting.

FAQs

1. How often should I replace my SRAM PC-1170 chain?

You should replace the PC-1170 chain once it reaches 0.5% to 0.75% wear, typically after 2,000 to 3,500 miles, depending on riding conditions.

2. Can I reuse the SRAM PowerLock quick link?

No, SRAM recommends replacing the PowerLock each time you remove the chain, as it is designed for one-time use.

3. What is the best lubricant for the PC-1170 chain?

For dry conditions, use a wax-based lube [paid link]. For wet conditions, a wet lube [paid link] with water resistance is best.

4. Can I use the PC-1170 chain on a 10-speed drivetrain?

No, the PC-1170 is an 11-speed chain and is not compatible with 10-speed systems.

5. Why is my PC-1170 chain noisy after installation?

It may need proper lubrication, fine-tuning of derailleur settings, or it could be breaking in. Check alignment and tension to resolve the issue.
