Tools Required
Before you begin, gather the necessary tools to ensure a smooth installation and adjustment process:
- 3mm, 4mm, and 5mm Allen wrenches [paid link]
- Shimano ST-4700 [paid link] shifters (left and right)
- Torque wrench [paid link]
- Cable cutters
- A small flathead screwdriver
- Chain whip (for removing the cassette if necessary)
- Lubricant (grease or chain oil)
- Replacement cables (if necessary)
Installation of Shimano ST-4700 Shifters
Installing the Shimano ST-4700 shifters requires attention to detail to ensure smooth, precise shifting performance. Here’s a step-by-step guide:
1. Remove Old Shifters (If Applicable)
If you’re replacing old shifters, begin by removing the existing ones. Use the appropriate size Allen wrench [paid link] to remove the screws securing the shifters to the handlebars. Slide them off carefully.
2. Install the Left and Right Shifters
The left shifter controls the front derailleur, while the right shifter controls the rear derailleur. Slide the new Shimano ST-4700 shifters onto their respective handlebars. Be sure to place the left shifter on the left side and the right shifter on the right side. Tighten the mounting bolts securely with a torque wrench [paid link].
3. Install the Brake and Shift Cables
Shimano ST-4700 shifters come with separate cable routing for the brake and shift systems. First, install the brake cable through the brake lever mechanism and ensure it is taut. Then, install the shift cable by threading it through the shift cable housing, making sure it’s securely attached to both the front and rear derailleurs.
4. Set Cable Tension
Use the barrel adjusters on the shifters to set the initial cable tension. This is crucial for ensuring smooth shifting. We’ll dive into finer adjustments in the following sections.
5. Test Shifting
Once everything is installed and the cables are tensioned, test the shifting. Shift through all the gears to ensure the front and rear derailleurs are functioning correctly.
Adjusting Shimano ST-4700 Shifters for Smooth Gear Changes
Proper adjustment is key to ensuring smooth, responsive shifts. Here’s how to fine-tune your Shimano ST-4700 shifters:
1. Front Derailleur Adjustment
To adjust the front derailleur, you’ll need to ensure proper cable tension, limit screw positions, and alignment.
- Cable Tension: With the front derailleur in the smallest chainring, adjust the barrel adjuster on the left shifter to achieve the correct tension. The derailleur should move freely without rubbing the chain in the smallest chainring.
- Limit Screws: Set the limit screws on the front derailleur to ensure it doesn’t shift beyond the smallest or largest chainrings.
- Alignment: Check the alignment of the front derailleur with the chainrings to ensure it moves properly. The derailleur cage should be parallel to the chainrings.
2. Rear Derailleur Adjustment
For the rear derailleur, the process involves adjusting both the derailleur’s position and cable tension.
- Cable Tension: Shift to the smallest cog and adjust the barrel adjuster on the right shifter to achieve proper tension. Ensure that the derailleur moves smoothly across all gears.
- Limit Screws: Adjust the high and low limit screws on the rear derailleur to prevent it from shifting past the smallest or largest cog.
- Indexing: As you shift through the gears, ensure each click corresponds with an exact gear. Use the barrel adjuster for fine-tuning.
3. Fine-Tuning Shift Performance
After adjusting cable tension and derailleur positions, test the shifters by riding and shifting through all gears. Fine-tune the barrel adjusters as needed to eliminate any skipping or hesitation in shifting.
Maintenance of Shimano ST-4700 Shifters
Routine maintenance ensures your Shimano ST-4700 shifters perform at their best for longer periods of time. Here’s how to keep them in top shape:
1. Clean Your Shifters Regularly
Dirt and grime can accumulate on your shifters, causing sluggish performance. Use a soft cloth and a mild degreaser to clean the body and levers of your shifters. Avoid harsh chemicals that can damage the finish.
2. Lubricate the Cables
Lubricating the shift cables is essential for smooth operation. Apply lubricant to the cables regularly to reduce friction and ensure smooth shifting.
3. Inspect and Replace Cables
Inspect the shift cables periodically for wear and fraying. Replace them if they show signs of damage to prevent poor shifting performance. For a smoother feel, replace the cables with Shimano’s recommended cables.
4. Keep the Derailleurs Clean
Clean your derailleurs after every few rides to avoid any buildup of dirt and debris that can hinder shifting performance. A quick wipe with a clean cloth will keep the derailleur functioning smoothly.
Troubleshooting Common Shimano ST-4700 Shifter Issues
Even with the best maintenance, issues can still occur. Below are some common problems and their solutions:
1. Shifters Are Stiff or Unresponsive
If the shifters feel stiff or don’t respond well, it could be due to dirty or dry cables. Clean and lubricate the cables, and ensure proper cable tension.
2. Chain Slips or Hesitates During Shifting
This issue can occur if the derailleur is misaligned, the cables are stretched, or the chainrings and cassette are worn. Check and adjust the derailleur position, replace the chain if necessary, and ensure the cables are correctly tensioned.
3. Shifting Is Noisy or Delayed
Noise or delays in shifting can be due to improper indexing or cable tension. Revisit the barrel adjusters and fine-tune until the shifting is smooth and precise.
Conclusion
The Shimano ST-4700 shifters are a reliable and efficient choice for cyclists looking for smooth, dependable shifting. By following the proper installation, adjustment, and maintenance steps outlined in this guide, you can ensure that your ST-4700 shifters perform optimally for years to come. Whether you’re installing new shifters, adjusting for better performance, or troubleshooting common issues, this guide equips you with all the knowledge you need to maintain your bike’s shifting system.
