The Shimano FC-5700 [paid link] crankset, part of the 105 10-speed groupset, is a reliable choice for road cyclists seeking durability and efficiency. Proper installation and maintenance are crucial to ensuring optimal power transfer, smooth shifting, and long-lasting performance. This guide will take you through the entire process—from installation to maintenance—so you can keep your FC-5700 [paid link] crankset running at its best.
Tools Required [paid links]
To install and maintain the Shimano FC-5700 [paid link] crankset, you will need:
- 5mm Allen wrench
- Shimano TL-FC16 crank arm preload tool
- Torque wrench with 5–14 Nm range
- Grease
- Crank arm removal tool (if replacing)
- Rag and degreaser for cleaning
Installing the Shimano FC-5700 Crankset
Step 1: Preparing the Bottom Bracket
Before installing the crankset, ensure that your bike frame is equipped with a compatible Hollowtech II bottom bracket. If you are installing a new bottom bracket:
- Clean the bottom bracket shell thoroughly, removing any old grease and debris.
- Apply grease to the threads of the bottom bracket cups to prevent corrosion and creaking.
- Use a Shimano Hollowtech II bottom bracket tool [paid link] to thread the cups into the frame securely. Tighten them to 35-50 Nm torque.
Step 2: Installing the Crank Arms
The Shimano FC-5700 crankset uses a two-piece design, simplifying installation.
- Apply a thin layer of grease to the spindle to prevent seizing.
- Slide the right-side crank arm (with chainrings attached) through the bottom bracket. Ensure it is fully seated.
- Position the left crank arm onto the spindle splines at a 180-degree opposite angle from the right crank arm.
- Insert and tighten the preload cap using a Shimano preload tool. The cap should be snug but not overtightened.
- Tighten the crank arm pinch bolts alternately using a 5mm Allen key. Torque them to 12-14 Nm to ensure even clamping force.
Adjusting the Shimano FC-5700 Crankset
A properly adjusted crankset ensures smooth power transfer and minimal wear on drivetrain components.
Checking for Play
- After installation, check for lateral play by holding both crank arms and trying to move them side to side.
- If play is present, slightly tighten the preload cap and retighten the pinch bolts.
Ensuring Proper Chainline
- The Shimano FC-5700 crankset is designed for a 10-speed drivetrain.
- Ensure that the crankset aligns correctly with the front derailleur and cassette.
- A misaligned chainline can cause shifting issues and excessive drivetrain wear.
Maintaining the Shimano FC-5700 Crankset
Routine maintenance ensures your crankset performs optimally and lasts longer.
Cleaning the Crankset
- Remove the crankset every few months (or more frequently in wet conditions) for deep cleaning.
- Use a degreaser and brush to clean the chainrings and spindle.
- Wipe down the crank arms with a soft cloth to maintain their finish.
Lubricating and Protecting Against Wear
- Apply fresh grease to the spindle and bottom bracket interface when reinstalling.
- Regularly check for worn chainrings or loose bolts, as these can affect performance.
Troubleshooting Common Issues
1. Creaking or Noisy Crankset
- Cause: Dirt or lack of lubrication in the bottom bracket or crank interface.
- Fix: Remove, clean, and regrease all contact surfaces.
2. Loose Crank Arm
- Cause: Insufficient torque on pinch bolts or preload cap.
- Fix: Tighten the preload cap first, then torque the pinch bolts to 12-14 Nm.
3. Poor Shifting Performance
- Cause: Chainring wear or incorrect front derailleur setup.
- Fix: Inspect chainrings for wear and adjust derailleur positioning.

FAQs
1. How often should I clean and regrease my Shimano FC-5700 crankset?
For optimal performance, clean and regrease every 2-3 months or after riding in wet/muddy conditions.
2. Can I use an 11-speed chain with the FC-5700 crankset?
While possible, it’s not recommended. The FC-5700 is designed for a 10-speed drivetrain, and an 11-speed chain may affect shifting performance.
3. What torque should I apply to the crank arm bolts?
The crank arm pinch bolts should be tightened to 12-14 Nm, and the bottom bracket cups to 35-50 Nm.
4. How do I know when my chainrings need replacement?
Replace chainrings if you notice shark-tooth wear patterns or poor shifting performance.
5. Is the FC-5700 crankset compatible with a press-fit bottom bracket?
Yes, but you will need a Hollowtech II-compatible press-fit bottom bracket such as the Shimano SM-BB71-41B.
Conclusion
The Shimano FC-5700 crankset is a reliable, efficient choice for road cyclists, but proper installation and maintenance are key to ensuring longevity and performance. By following this guide, you can confidently set up, adjust, and maintain your crankset to keep your drivetrain running smoothly.
