Tools Required

Before you begin, make sure you have the following tools:

• 5 mm Allen key – For clamp bolt tightening
• 4 mm Allen key – For securing the cable
• 2 mm Allen key – For fine-tuning the support bolt
• Phillips screwdriver #2 – For high and low limit screw adjustments
• Shimano TL-FD68 tool – For cable alignment and converter adjustment
• Torque wrench [paid link] – To ensure proper tightening
• Bike grease and lubricant – To prevent cable friction and enhance shifting performance

Installing the Shimano FD-4700

1. Mounting the Front Derailleur

For a Band-Type Mount

1. Position the derailleur on the seat tube, aligning the outer cage with the largest chainring.
2. Adjust the height so that the gap between the derailleur’s outer plate and the largest chainring is 1–3 mm.
3. Lightly tighten the clamp bolt using a 5 mm Allen key. This will allow for fine adjustments later.

For a Braze-On Mount

1. Secure the derailleur to the frame’s mount, ensuring correct positioning.
2. Use a support bolt to prevent excessive flex and ensure a firm connection.
3. Adjust height and angle to achieve 1–3 mm clearance above the chainring.

2. Connecting the Shifting Cable

1. Ensure the front shifter is in the lowest gear (small chainring).
2. Route the cable properly through the derailleur’s cable guide.
3. Use the TL-FD68 tool to determine the correct converter setting (ON or OFF).
4. Pull the cable taut and secure it using the 4 mm Allen key.
5. Check for slack and adjust tension using the barrel adjuster.

Adjusting the Shimano FD-4700

1. Setting the Low Limit Screw

• Shift to the smallest chainring and largest rear sprocket.
• Adjust the low limit screw until there is 0–0.5 mm clearance between the chain and inner derailleur plate.

2. Fine-Tuning Cable Tension

• Shift to the largest chainring and check derailleur alignment.
• Adjust the barrel adjuster to ensure snappy, smooth shifts without chain rub.

3. Setting the High Limit Screw

• Shift to the largest chainring and smallest rear sprocket.
• Adjust the high limit screw until there is 0–0.5 mm clearance between the chain and outer derailleur plate.
