Shimano’s ST-5700 [paid link] shifters are a key component of their 105 series, designed for road bikes and offering smooth, precise shifting performance. Whether you’re installing a brand-new set of ST-5700 [paid link] shifters or maintaining your existing ones, ensuring they’re set up correctly is crucial for smooth gear changes and a seamless riding experience.

In this guide, we’ll cover everything you need to know about installing, adjusting, and maintaining Shimano ST-5700 [paid link] shifters. We will also explore common issues riders face, troubleshooting tips, and best practices for keeping your shifters in top shape for years to come.

Tools Required

Before you begin the installation or adjustment of your Shimano ST-5700 shifters, gather the following tools:

  • 5mm Allen wrench [paid link]
  • Flathead screwdriver
  • Phillips screwdriver
  • Cable cutters
  • 10mm wrench
  • Torque wrench [paid link] (optional but recommended)
  • Chain checker tool (optional, for checking chain wear)
  • Shimano-compatible cable (for replacements)
  • Lubricant for cables (optional)
  • Clean cloth

Installation of Shimano ST-5700 Shifters

The installation of the Shimano ST-5700 shifters involves several precise steps. Ensure that you follow these instructions carefully to avoid any shifting issues later on.

Step 1: Mount the Shifters

  1. Position the shifters: Insert the shifters into the handlebars. Make sure the clamps are facing forward, and the shifters are in a comfortable riding position.
  2. Secure the shifters: Use your 5mm Allen wrench [paid link] to tighten the clamp bolts. Tighten them to the manufacturer’s recommended torque specification. For Shimano shifters, this is typically around 5–6 Nm.

Step 2: Install the Brake and Shift Cables

  1. Thread the cables: Insert the shift cables through the shifter housings and connect them to the shift levers. Make sure the cables are properly aligned to avoid unnecessary friction.
  2. Install the brake cables: Repeat the same procedure for the brake cables, ensuring that they are running smoothly through the housing and are not kinked or bent.
  3. Attach the cables to the derailleurs: Follow the specific routing instructions for the front and rear derailleurs. Ensure the cables are securely clamped into place.

Step 3: Install the Shift Levers on the Bars

  1. Check position and comfort: Position the shifters so that they align with your handlebars. It’s important that you can comfortably reach the shifters while riding.
  2. Final tightening: Once you’re satisfied with the positioning, tighten the clamp bolts to secure the shifters in place.

Adjusting Shimano ST-5700 Shifters

Once the ST-5700 shifters are installed, proper adjustment is key to smooth shifting. This process involves fine-tuning both the front and rear derailleur settings.

Front Derailleur Adjustment

  1. Set the limits: Use a 5mm Allen wrench [paid link] to adjust the front derailleur’s limit screws. This ensures the derailleur doesn’t overshoot the smallest or largest chainrings.
  2. Adjust the cable tension: Using the barrel adjuster, fine-tune the cable tension to ensure smooth shifting between the front chainrings. If the front derailleur is slow to shift, increase the tension slightly. If it shifts too far, reduce the tension.

Rear Derailleur Adjustment

  1. Check the derailleur hanger alignment: Ensure the derailleur hanger is straight. If it is bent, it can cause issues with shifting precision.
  2. Adjust the limit screws: Adjust the limit screws on the rear derailleur to prevent the chain from overshooting the largest or smallest cog.
  3. Fine-tune the cable tension: Use the barrel adjuster on the rear derailleur or shifter to make small adjustments to the tension of the cable. This will affect how quickly the derailleur moves across the cassette.

Fine-tuning Shifting Performance

After performing the basic adjustments, test the shifting and fine-tune the cable tension further for smoother gear changes. A quick ride around the block can help you identify any issues.

Maintaining Shimano ST-5700 Shifters

To keep your Shimano ST-5700 shifters performing at their best, regular maintenance is essential. Follow these steps to extend their lifespan and maintain smooth shifting.

1. Cleaning the Shifters

  1. Wipe down the shifters: Use a clean, dry cloth to wipe off dirt and grime. Avoid using harsh chemicals that could damage the components.
  2. Lubricate the cables: Occasionally, apply a small amount of lubricant to the cables and housing to ensure smooth movement. Be careful not to over-lubricate, as excess lubricant can attract dirt and debris.

2. Checking for Cable Wear

Regularly inspect your shift cables for fraying or signs of damage. Worn cables can affect shifting performance. Replace the cables if necessary.

3. Adjusting the Shifters Periodically

Shifting performance may degrade over time due to cable stretch or wear. Regularly check and adjust your shifters to keep them in top condition. If shifting becomes sluggish or inconsistent, it may be time for a tune-up.

Troubleshooting Common Issues with Shimano ST-5700 Shifters

Even with proper maintenance, you may encounter some common shifting issues. Here’s how to diagnose and fix them:

1. Sluggish or Stiff Shifting

If your shifters feel sluggish or stiff:

  • Check the cables: Friction in the cables can cause stiffness. Inspect the cables for wear and replace them if needed.
  • Lubricate the cables: Apply some lube to the cables and test again.
  • Adjust cable tension: If the cable tension is too high, it can lead to stiff shifting. Adjust the barrel adjuster to reduce tension.

2. Inconsistent Shifting

If the shifting feels inconsistent or the chain skips gears:

  • Check derailleur alignment: Ensure that both the front and rear derailleurs are properly aligned.
  • Inspect the cassette and chain: A worn cassette or chain can lead to poor shifting performance. Use a chain checker to measure wear.
  • Check the shifter: The shifter mechanism itself may need cleaning or lubrication.

Shimano ST-5700 Shifter Compatibility

The Shimano ST-5700 shifters are designed for use with Shimano’s 105 series drivetrain, which is known for its reliability and performance. However, compatibility with other drivetrain components should always be checked.

Front and Rear Derailleur Compatibility

  • The Shimano ST-5700 shifters are compatible with Shimano 105, Tiagra, and some other Shimano road derailleurs.
  • It is recommended to pair them with Shimano 105 front and rear derailleurs for the best performance.

Chain and Cassette Compatibility

  • These shifters are designed for use with Shimano 10-speed cassettes and chains. Be sure to choose compatible components to ensure smooth shifting.

Conclusion

Installing, adjusting, and maintaining Shimano ST-5700 shifters requires careful attention to detail, but with the right techniques, you can ensure your shifting is smooth and precise for years. Regular maintenance, including cleaning, lubrication, and cable inspection, is key to avoiding issues. If you experience shifting problems, troubleshooting steps can help you quickly get your system back in top shape.
