The Shimano CN-5701[paid link] chain is a high-quality, 10-speed chain designed for road bike drivetrains. As part of the Shimano 105 series, it balances durability, efficiency, and cost-effectiveness. Proper installation and maintenance of the CN-5701[paid link] chain are crucial for ensuring smooth shifting, extending drivetrain longevity, and optimizing pedaling efficiency.

This guide provides a step-by-step approach to installing, adjusting, and maintaining the Shimano CN-5701 chain. We will cover tools required, best practices, troubleshooting techniques, and expert maintenance tips to maximize performance.

Tools Required

Before installing your CN-5701 chain, gather the following tools:

  • Chain breaker tool
  • Quick-link pliers (if using a quick link)
  • Chain wear gauge
  • Shimano-approved chain lubricant
  • Clean rag or brush
  • Degreaser (for deep cleaning)
  • Ruler (for verifying chain length)

How to Install the CN-5701 Chain

1. Measuring and Sizing the Chain

The correct chain length ensures optimal shifting and drivetrain efficiency. Follow these steps to determine the ideal length:

  • Method 1: Big Chainring and Largest Cog
    • Shift the bike into the largest front chainring and largest rear cog.
    • Without threading the chain through the derailleur, pull it tight.
    • Add two full links (one inner and one outer link) to allow proper derailleur tension.
  • Method 2: Matching the Old Chain
    • If your old chain was correctly sized, lay it next to the new CN-5701 chain and match the length.
    • Ensure the chain isn’t stretched by checking it with a chain wear gauge.

2. Installing the Chain

  • Thread the CN-5701 chain through the front derailleur, rear derailleur jockey wheels, and cassette.
  • Join the ends of the chain using a Shimano connecting pin or a quick link.

3. Securing the Chain with a Shimano Connecting Pin

  • Insert the special Shimano connecting pin into the link.
  • Use a chain tool to push the pin fully through until it is flush.
  • Break off the excess pin with pliers.

4. Using a Quick Link (Alternative Method)

  • Insert the quick-link ends into each side of the chain.
  • Align the link and pull the pedals backward until it clicks into place.
  • Use quick-link pliers for extra security if necessary.

How to Adjust the CN-5701 Chain for Optimal Performance

1. Checking Chain Tension

  • A properly tensioned chain should allow smooth shifting without excessive slack.
  • Shift through all gears and observe if the chain sags or appears too tight.

2. Aligning the Chain for Smooth Shifting

  • Ensure the chain runs smoothly over the jockey wheels without excessive noise.
  • If shifting feels sluggish or rough, fine-tune derailleur cable tension.

3. Ensuring Proper Front and Rear Derailleur Alignment

  • Misalignment can cause skipping or excessive noise.
  • Use barrel adjusters on the derailleurs to fine-tune shifting response.

How to Maintain the CN-5701 Chain

1. Cleaning the Chain

  • Wipe down the chain after every ride using a dry cloth.
  • For deeper cleaning, use a chain degreaser and a brush to remove grime.

2. Lubricating the Chain

  • Apply a Shimano-approved chain lubricant to each link.
  • Allow it to sit for a few minutes, then wipe off excess lube to prevent dirt buildup.

3. Checking for Chain Wear

  • Use a chain wear gauge to check stretch. Replace the chain when it reaches 0.5% wear to prevent excessive cassette and chainring wear.

Troubleshooting Common CN-5701 Chain Issues

1. Skipping or Slipping Chain

  • Possible causes: Chain wear, incorrect length, or derailleur misalignment.
  • Solution: Replace a worn chain, adjust derailleur, and check cassette wear.

2. Noisy Chain While Pedaling

  • Possible causes: Dry or dirty chain, misalignment.
  • Solution: Clean, lubricate, and check for proper derailleur setup.

3. Difficulty Shifting Gears

  • Possible causes: Cable tension issues, chain wear, or debris buildup.
  • Solution: Adjust cable tension, clean the chain, and check for excessive wear.

Conclusion

The Shimano CN-5701 chain is an essential component for smooth shifting and drivetrain longevity. Proper installation, regular maintenance, and timely replacement will ensure optimal performance. By following the steps outlined in this guide, you can maximize your chain’s lifespan and keep your ride running smoothly.
