The Shimano FC-5700 [paid link] chainring is a critical component of the Shimano 105 5700 crankset, a popular choice among road cyclists for its balance of durability, performance, and affordability. Proper installation, adjustment, and maintenance of this chainring ensure smooth shifting, optimal power transfer, and an extended lifespan.

In this guide, we’ll walk you through the complete process of installing, adjusting, and maintaining the Shimano FC-5700 [paid link] chainring to keep your drivetrain performing at its best.

Tools Required

You’ll need the following tools to install and maintain your FC-5700 [paid link] chainring properly:

  • 5mm Allen wrench [paid link]
  • Torque wrench [paid link] (with a 5mm hex bit)
  • Chainring nut wrench (optional)
  • Bottom bracket tool [paid link] (if removing crankset)
  • Degreaser and chain cleaner
  • Chain lubricant
  • Clean rag or brush

Step-by-Step Installation of the Shimano FC-5700 Chainring

1. Removing the Old Chainring

Before installing your new Shimano FC-5700 chainring, you need to remove the old one. Follow these steps:

  • Shift your chain to the smallest chainring and smallest cog to reduce tension.
  • Use a 5mm Allen wrench [paid link] to loosen the chainring bolts. Some chainrings use a separate backing nut, requiring a chainring nut wrench for stability.
  • Carefully remove the bolts and slide the old chainring off the crank spider.

2. Installing the New Chainring

  • Align the new FC-5700 chainring so that the pin behind the largest chainring aligns with the crank arm. This prevents chain jamming in case of derailment.
  • Insert the bolts and hand-tighten them in a crisscross pattern to ensure even pressure.
  • Using a torque wrench [paid link], tighten the bolts to Shimano’s recommended 10-12 Nm torque setting. Over-tightening can strip the threads, while under-tightening may cause shifting issues.

3. Reinstalling the Crankset (If Removed)

If you removed the crankset for installation, follow these steps to reinstall it:

  • Slide the crankset back onto the bottom bracket spindle.
  • Tighten the preload cap using a bottom bracket tool [paid link].
  • Secure the crank arm bolts evenly using a 5mm Allen wrench [paid link], torquing them to 12-14 Nm.

Adjusting Your Shimano FC-5700 Chainring for Optimal Performance

1. Front Derailleur Alignment

To ensure smooth shifting, your front derailleur must be properly aligned with the chainring:

  • Position the derailleur 1-3mm above the largest chainring teeth.
  • The cage should be parallel to the chainring to prevent rubbing.
  • Use a 2mm Allen wrench to adjust the limit screws, ensuring smooth shifting without excessive movement.

2. Chain Length and Tension

  • A properly sized chain improves shifting and drivetrain efficiency.
  • Use the big-big method (largest chainring and largest cog, without threading through the derailleur) to size the chain.
  • Add two extra links before cutting the chain for proper tension.

3. Fine-Tuning Shifting Performance

If you experience poor shifting, try these adjustments:

  • Cable Tension: Use the barrel adjuster to fine-tune shifting.
  • B-Tension Screw: Adjust if the chain jumps or hesitates between rings.
  • Chainring Wear: Check for hooked teeth or excessive wear, as this can cause shifting delays.

Maintaining the Shimano FC-5700 Chainring for Longevity

1. Cleaning Your Chainring Regularly

  • Use a degreaser and a brush to remove built-up grime.
  • Wipe down with a clean rag and apply dry or wet chain lubricant depending on riding conditions.
  • Avoid excessive lubrication, as this attracts dirt and accelerates wear.

2. Checking for Wear and Damage

  • Look for shark-tooth-shaped teeth (a sign of excessive wear).
  • If shifting performance declines despite adjustments, the chainring may need replacement.
  • Inspect bolts and re-torque them regularly to prevent loosening.

3. Chain and Cassette Compatibility

  • Use a compatible Shimano 10-speed chain for the best performance.
  • Replace your chain every 2,000-3,000 miles to prevent premature chainring wear.
  • A worn chain accelerates chainring and cassette degradation, leading to poor shifting.

Common Issues and Troubleshooting

1. Noisy Pedaling or Creaking

  • Check for loose chainring bolts and torque them to 10-12 Nm.
  • Inspect the bottom bracket for wear or contamination.
  • Apply anti-seize or grease on the bolts to prevent creaking.

2. Poor Front Shifting Performance

  • Ensure the front derailleur is aligned properly and that limit screws are adjusted correctly.
  • Check if the chain is worn and replace it if necessary.
  • Inspect the cable tension and barrel adjuster for precise shifting.

Conclusion

Proper installation, adjustment, and maintenance of your Shimano FC-5700 chainring are essential for smooth shifting and drivetrain longevity. By following this guide, you can ensure your chainring performs at its best, whether you’re replacing an old ring or fine-tuning your bike for optimal efficiency.

Regular cleaning, correct torque application, and proper front derailleur adjustment will help you avoid common issues like noisy pedaling and sluggish shifting. If problems persist, consider replacing worn components and ensuring compatibility with your drivetrain.

By maintaining your FC-5700 chainring, you’ll enjoy a smoother ride, better power transfer, and a longer lifespan for your entire drivetrain.
