The PC-1170 [paid link] chain, part of SRAM’s Force 22 groupset, is designed for high-performance road cycling. It features HollowPin™ technology for improved strength, efficiency, and reduced weight. Proper installation, adjustment, and maintenance of this chain are essential for longevity and smooth shifting.

This guide provides step-by-step instructions on setting up and maintaining the SRAM PC-1170 [paid link] chain, helping you avoid common issues that can lead to premature wear and poor drivetrain performance.

To install and maintain the PC-1170 chain, you’ll need:

Installation of the PC-1170 Chain

Step 1: Measure and Cut the Chain

The PC-1170 is sold in a standard length of 114 links. Before installing, determine the appropriate length:

  1. Wrap the chain around the largest chainring and largest cog (without passing through the rear derailleur).
  2. Add two extra links to allow for proper tension.
  3. Use a chain breaker tool to remove excess links.

Step 2: Install the Chain on the Drivetrain

  1. Route the chain through the front derailleur cage and around the cassette.
  2. Pass it through the jockey wheels of the rear derailleur, ensuring proper orientation.

Step 3: Connect the Chain Using a PowerLock Link

SRAM’s PC-1170 uses a PowerLock quick link for tool-free connection:

  1. Align the PowerLock link ends and snap them into place.
  2. Rotate the cranks so the PowerLock link is positioned on the top of the chain run.
  3. Apply downward pedal pressure to fully engage the link.

Important: SRAM PowerLock links are single-use—always replace them when reinstalling the chain.

Adjustment of the PC-1170 Chain

Step 1: Check Chain Tension and Length

  1. The chain should have minimal slack but not be overly tight.
  2. Verify proper derailleur alignment and chain wrap over the cassette and chainrings.

Step 2: Fine-Tune the Rear Derailleur for Optimal Shifting

  1. Shift through all gears and check for hesitation or chain skipping.
  2. Adjust the B-tension screw to fine-tune the derailleur’s position relative to the cassette.
  3. If necessary, use barrel adjusters to align the derailleur pulleys with the cassette cogs.

Step 3: Test Front Derailleur Performance

  1. Shift between chainrings to ensure smooth transitions.
  2. If the chain rubs against the front derailleur plates, adjust the limit screws for precise alignment.

Maintenance of the PC-1170 Chain

Regular Cleaning Routine

A dirty chain accelerates wear and reduces drivetrain efficiency. Follow these steps for optimal chain care:

  1. Wipe down the chain after every ride using a dry rag.
  2. Apply degreaser every 200–300 miles and scrub with a brush.
  3. Rinse and dry completely before lubricating.

Lubrication Best Practices

  1. Use a high-quality chain lubricant (wet or dry, depending on riding conditions).
  2. Apply a thin layer to each roller while backpedaling.
  3. Let it sit for a few minutes, then wipe off excess to prevent dirt buildup.

Checking for Wear and When to Replace

  1. Use a chain checker tool to measure stretch. If the reading is 0.5%–0.75% wear, replace the chain to prevent cassette damage.
  2. A worn chain can lead to skipping gears and poor shifting performance.

Troubleshooting Common PC-1170 Chain Issues

1. Noisy Chain or Skipping Gears

  • Check for proper chain lubrication.
  • Inspect for worn-out cassette teeth or chain elongation.
  • Adjust the derailleur’s cable tension.

2. Chain Dropping Off the Chainring

  • Verify that the front derailleur is aligned correctly.
  • Adjust the limit screws to prevent overshifting.

3. PowerLock Link Not Engaging Properly

  • Ensure the link is installed in the top chain run before locking it into place.
  • Apply firm pedal pressure to secure the connection.

Comparing the PC-1170 to Similar Chains

The PC-1170 competes with other 11-speed chains such as:

  • Shimano HG701: Features Sil-Tec coating for quieter shifting but is heavier.
  • KMC X11SL: Known for excellent durability and lightweight hollow plates.
  • SRAM RED 22: A higher-end option with improved efficiency but at a premium cost.

While the PC-1170 offers a great balance of weight, performance, and cost, it requires regular maintenance to keep shifting smooth.

Final Thoughts

The SRAM PC-1170 chain is a solid choice for road cyclists looking for a durable, high-performance 11-speed chain. By following proper installation, adjustment, and maintenance techniques, you can extend its lifespan and ensure optimal shifting performance.
