Installing a Shimano FC-5700 [paid link] crankset correctly is crucial to ensure smooth performance and reliable power transfer. Improper installation can lead to a range of issues, including poor shifting, uncomfortable rides, and even component failure. This guide will focus on the most common installation mistakes cyclists make when setting up the Shimano FC-5700 [paid link] crankset, how to avoid them, and the proper installation techniques that will keep your bike running efficiently.

1. Using the Wrong Tools for the Job

Before diving into the installation process, it’s essential to gather the correct tools. Using improper or low-quality tools can damage components, leading to more significant issues down the line.

Tools Required:

• Shimano Hollowtech II Crankset Tool
• 8mm Allen wrench [paid link]
• Torque wrench [paid link] (preferably with 30-50Nm torque range)
• Crank arm puller (for removing crank arms, if necessary)
• Grease (light)
• T20 or T25 Torx driver (depending on your crankset’s specific requirements)

Using the correct tools ensures that you apply the right amount of torque and install the crankset securely without causing any damage. Inadequate torque could lead to parts coming loose during use, while excessive torque might strip the threads or damage the crank arms.

2. Failing to Grease the Spindle

One of the most critical steps in installing the Shimano FC-5700 [paid link] crankset is properly greasing the spindle. Skipping this step can lead to increased friction and result in the crankset becoming difficult to remove later or cause squeaking noises during rides. Greasing the spindle ensures smooth rotation, reduces wear, and prevents creaking.

Solution:

• Lightly grease the spindle before installing the crank arms.
• Avoid over-greasing, as too much grease can attract dirt and grime, causing further issues.

3. Incorrect Installation of the Crank Arms

Installing the crank arms incorrectly is a common mistake, especially when it comes to tightening them onto the spindle. Improper alignment or misinstallation of the left or right crank arm can lead to a misaligned drivetrain, poor pedaling efficiency, and excess strain on the bottom bracket and other components.

Solution:

• Ensure the crank arms are installed on the correct sides. The left crank arm should be on the non-drive side (left side), while the right crank arm should be on the drive side (right side).
• Use the correct orientation to align the crank arm onto the spindle. Some cranks have specific markings to ensure proper alignment.
• Tighten the crank arms to the recommended torque value, typically between 30-40Nm for the FC-5700 crankset.

4. Not Properly Tightening the Crank Arm Bolts

Under-tightening or over-tightening the crank arm bolts can lead to disastrous consequences. If the bolts are too loose, the crank arms may come off during a ride, causing serious injury or damage. On the other hand, over-tightening can damage the crank arms and lead to difficulty removing them later.

Solution:

• Tighten the crank arm bolts to the specified torque, typically 12-14Nm for Shimano cranksets.
• Use a torque wrench [paid link] to ensure accurate tightening.
• Check the bolts for tightness after the initial installation and periodically after riding to ensure they remain secure.

5. Skipping the Bottom Bracket Installation or Maintenance

The bottom bracket is the interface between the crankset and the bike frame. Skipping the installation or maintenance of the bottom bracket is one of the most common installation mistakes when setting up a Shimano FC-5700 crankset. An improperly installed or poorly maintained bottom bracket can cause issues like poor pedaling efficiency, misalignment, and wear on the crankset.

Solution:

• Install a Shimano Hollowtech II compatible bottom bracket according to the manufacturer’s instructions.
• Make sure the bottom bracket is correctly installed, with no play or movement when the crankset is attached.
• Regularly clean and grease the bottom bracket threads to avoid issues with creaking and to maintain proper rotation.

6. Overlooking the Pedal Thread Lubrication

Pedal installation is often overlooked during crankset installation, but it’s just as important. Without proper lubrication of the pedal threads, the pedals can become seized or difficult to remove. This can make future pedal swaps a hassle and potentially damage the crank arms.

Solution:

• Apply a small amount of grease to the pedal threads before installing the pedals.
• Ensure the pedals are threaded in correctly—left pedal on the left side and right pedal on the right side.
• Tighten the pedals securely, ensuring they are installed straight without cross-threading.

7. Not Checking for Proper Crankset Alignment

Another common mistake when installing the Shimano FC-5700 crankset is neglecting to check for proper crankset alignment. An improperly aligned crankset can cause misalignment in the drivetrain, poor shifting performance, and unnecessary strain on the system.

Solution:

• After installing the crank arms, double-check that both cranks are aligned and are evenly spaced relative to the bike frame.
• Use a crankset alignment tool to ensure that the crankset is positioned correctly.

8. Forgetting to Perform a Final Torque Check

Once the installation is complete, many cyclists forget to double-check the torque on the crankset bolts and pedal threads. This can lead to a host of issues, such as loose crank arms or pedals, which can compromise the safety and performance of your ride.

Solution:

• Perform a final torque check using a torque wrench [paid link] to ensure all bolts are tightened to the recommended values.
• Verify that the pedals are secure and the crank arms are firmly attached.

9. Not Cleaning and Lubing the Chainrings

The chainrings play a vital role in the overall performance of the drivetrain, and failure to clean or lubricate them during installation can lead to premature wear and poor performance. Dirt buildup on the chainrings can also cause shifting issues and increase the likelihood of chain wear.

Solution:

• Before installing the crankset, thoroughly clean the chainrings using a degreaser to remove dirt and grime.
• Apply a small amount of lubricant to the teeth of the chainrings to ensure smooth and quiet operation.

10. Ignoring Crankset Testing After Installation

The final step of installing the Shimano FC-5700 crankset is testing it thoroughly before taking it on the road. Ignoring this critical testing phase can result in missed issues that can affect your riding experience or even lead to breakdowns during a ride.

Solution:

• Once the crankset is installed, test it by spinning the cranks and checking for smooth pedal movement.
• Check for any unusual noises, such as creaking or grinding, which could indicate improper installation or the need for further adjustments.

By avoiding these common Shimano FC-5700 crankset installation mistakes, you can ensure your bike runs smoothly and performs at its best. Proper installation, maintenance, and adjustments are crucial to prolonging the life of your crankset and maximizing your cycling experience.
