Key Features:

• Compatible with 10-speed HG-X chains.
• 2-piece cap-free design for quick and easy installation, offering lighter weight and increased stiffness compared to traditional crank/bottom bracket assemblies.
• SG-X chainrings with strategically placed chain receiving pins and tooth profiles for fast and reliable shifting.
• Designed for use with Hollowtech II type bottom bracket cups and shells.

2. Safety Information

Always prioritize safety when working with bicycle components. Improper installation or maintenance can lead to serious injury or damage to your bicycle.

• Professional Installation Recommended: If you are not experienced with bicycle mechanics, it is highly recommended to have this component installed by a qualified bicycle technician.
• Read Instructions Carefully: Before attempting any installation or adjustment, read this manual thoroughly.
• Use Correct Tools: Always use the appropriate tools for installation and maintenance. Using incorrect tools can damage the component.
• Torque Specifications: Adhere strictly to all specified torque values. Overtightening or undertightening bolts can lead to component failure.
• Regular Inspection: Periodically inspect the crankset for any signs of wear, damage, or loose components.
• Wear Safety Gear: Always wear appropriate safety gear, such as gloves and eye protection, when performing maintenance.

3. Package Contents

Upon opening the package, verify that all components are present and undamaged. The SHIMANO Tiagra FC-4700 crankset package typically includes:

• SHIMANO Tiagra FC-4700 Crankset (left and right crank arms with integrated spindle, and chainrings).

Note: This crankset is designed to be used with a Hollowtech II type bottom bracket, which is typically sold separately and not included with the crankset itself. Please ensure you have the correct compatible bottom bracket for your bicycle frame.

4. Setup and Installation

The SHIMANO Tiagra FC-4700 crankset utilizes a Hollowtech II 2-piece design, which integrates the bottom bracket axle with the right crank arm. This design requires a compatible Hollowtech II bottom bracket.

Required Tools (Not Included):

• Bottom bracket tool (e.g., SHIMANO TL-FC32 or equivalent)
• Crank arm fixing bolt tool (e.g., SHIMANO TL-FC16 or equivalent)
• Hex wrenches (typically 5mm)
• Torque wrench
• Grease

Installation Steps:

1. Prepare Bottom Bracket: Ensure your Hollowtech II bottom bracket is properly installed and torqued to the manufacturer's specifications. Apply a thin layer of grease to the spindle of the right crank arm.
2. Install Right Crank Arm: Carefully slide the right crank arm (with integrated spindle and chainrings) through the bottom bracket from the drive side of the bicycle frame.
3. Install Left Crank Arm: Align the splines of the left crank arm with the splines on the spindle. Push the left crank arm onto the spindle until it is fully seated.
4. Tighten Fixing Bolt: Install the crank arm fixing bolt (plastic cap) and tighten it by hand until snug. This bolt preloads the bearings. Do not overtighten.
5. Tighten Pinch Bolts: Alternately tighten the two pinch bolts on the left crank arm using a 5mm hex wrench. Tighten each bolt incrementally until they reach the specified torque (typically 12-14 Nm). Ensure even tension between the two bolts.
6. Check for Play: After tightening, check for any lateral play in the crankset. If play is present, re-check the fixing bolt and pinch bolts.
7. Final Inspection: Rotate the crankset to ensure smooth, unrestricted movement. Verify that all bolts are securely tightened to their specified torque values.

For detailed visual instructions, refer to the official SHIMANO dealer's manual or consult a professional bicycle mechanic.

5. Operating Instructions

The SHIMANO Tiagra FC-4700 crankset is designed for optimal performance within a 2x10 speed drivetrain system. Proper operation involves understanding its interaction with the front derailleur and chain.

• Shifting: Use your front shifter to move the chain between the smaller (inner) and larger (outer) chainrings. The SG-X chainrings are designed to facilitate smooth and quick shifts.
• Chain Compatibility: This crankset is specifically designed for use with 10-speed HG-X chains. Using incompatible chains may result in poor shifting performance and accelerated wear.
• Cross-Chaining: Avoid extreme cross-chaining (e.g., large chainring with largest rear cog, or small chainring with smallest rear cog) as this can increase wear on the chain and chainrings, and may lead to inefficient power transfer or chain drop.
• Cadence: Maintain a consistent and comfortable pedaling cadence for efficient power output and reduced strain on your knees and drivetrain components.

6. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your SHIMANO Tiagra FC-4700 crankset.

Cleaning:

• After Each Ride: Wipe down the crank arms and chainrings with a clean cloth to remove dirt and grime.
• Deep Cleaning: Periodically, use a degreaser specifically designed for bicycle drivetrains to clean the chainrings. Rinse thoroughly and dry. Avoid high-pressure washing directly on bearings.

Inspection:

• Chainring Wear: Inspect the teeth of the chainrings for excessive wear (e.g., 'shark fin' shape). Worn chainrings can lead to poor shifting and chain skip.
• Crank Arm Integrity: Check crank arms for any cracks, bends, or signs of damage.
• Bolt Tightness: Regularly check the tightness of the left crank arm pinch bolts and the crank arm fixing bolt. Ensure they are torqued to specifications.
• Bottom Bracket Play: Check for any play in the bottom bracket by rocking the crank arms side-to-side. If play is detected, the bottom bracket may need adjustment or replacement.

Lubrication:

• Chain: Keep your chain clean and properly lubricated according to your chain lubricant manufacturer's instructions. A well-lubricated chain reduces wear on chainrings.
• Spindle: When reinstalling the crankset, apply a thin layer of grease to the spindle to prevent corrosion and facilitate smooth installation.

7. Troubleshooting

This section addresses common issues you might encounter with your crankset.

• Crankset Noise (Clicking/Creaking):
  • Check if the left crank arm pinch bolts are tightened to the correct torque.
  • Inspect the bottom bracket for proper installation and tightness.
  • Ensure pedals are securely tightened to the crank arms.
  • Clean and re-grease the crank spindle and bottom bracket threads.
• Poor Front Shifting:
  • Verify that the front derailleur is correctly aligned and adjusted.
  • Check for chain wear or damage.
  • Ensure the chainrings are not excessively worn.
  • Confirm you are using a 10-speed HG-X compatible chain.
• Crankset Play:
  • Re-tighten the crank arm fixing bolt (plastic cap) and then the left crank arm pinch bolts to specification.
  • If play persists, the bottom bracket bearings may be worn and require replacement.

If you are unable to resolve an issue, consult a professional bicycle mechanic.
