The Shimano PD-6800[paid link] pedals are a favorite choice among road cyclists, offering a reliable and performance-driven solution. However, improper installation can lead to a range of issues that compromise both safety and comfort. In this article, we’ll outline common installation mistakes and how to avoid them to ensure your PD-6800[paid link] pedals perform optimally on every ride.
1. Incorrect Pedal Threading
One of the most common installation mistakes is improper threading of the pedals onto the crank arms. Each pedal has specific threading: the right pedal threads clockwise (right side) while the left pedal threads counterclockwise (left side). Failing to recognize this difference can damage the crank arm threads and make it difficult or impossible to install or remove the pedals in the future.
How to Avoid This Mistake:
- Ensure you’re installing the correct pedal on each side of the bike.
- Double-check the pedal markings: “L” for left and “R” for right.
- Use a torque wrench[paid link] to tighten pedals properly (usually around 35-55 Nm, depending on manufacturer recommendations).
2. Over-tightening the Pedals
Over-tightening is another common error that can lead to damage. It may seem like a good idea to tighten the pedals as much as possible, but doing so can cause stress on both the pedal and the crank arm. This can result in stripped threads, cracked crank arms, or even the failure of the pedal mechanism itself.
How to Avoid This Mistake:
- Use a torque wrench[paid link] to ensure the pedals are tightened to the correct specification.
- Refer to Shimano’s recommended torque setting for the PD-6800 pedals (typically around 35-55 Nm).
- Tighten the pedals in small increments and check for any movement after each turn.
3. Not Greasing the Pedal Threads
Another common mistake when installing the Shimano PD-6800 pedals is neglecting to grease the pedal threads. Without lubrication, the metal threads on both the pedal and crank arm can seize over time, especially if the pedals are removed frequently. This can lead to difficulty when removing the pedals and can cause permanent damage to the threads.
How to Avoid This Mistake:
- Apply a thin layer of grease to the pedal threads before installation.
- Make sure the grease is appropriate for metal components to prevent corrosion and ensure smooth installation.
4. Failing to Align Pedals Properly
Aligning the pedal correctly when threading it into the crank arm is crucial to avoid cross-threading. If the pedal is angled or not aligned properly, it can cause the threads to strip, making the pedal difficult to remove and potentially damaging the crank arm.
How to Avoid This Mistake:
- Hand-tighten the pedal initially to ensure it’s aligned correctly with the threads.
- Make sure the pedal is parallel to the crank arm before tightening it fully.
- Check the pedal alignment regularly during installation to ensure it threads smoothly.
5. Ignoring Pedal Maintenance During Installation
Some cyclists fail to check the pedal’s internal components during installation, especially the bearings and retention mechanisms. While the PD-6800 pedals are designed for durability, installing them without proper maintenance can lead to issues down the line, such as uneven engagement or premature wear.
How to Avoid This Mistake:
- Perform a quick inspection of the pedal bearings and engagement mechanism before installing the pedals.
- If necessary, clean and lubricate the pedal mechanism to ensure smooth operation and longevity.
6. Not Checking Pedal Clearance
Proper pedal clearance is crucial, especially when riding with clipless shoes. If the pedals are too tight against the crank arm or there isn’t enough space for the shoe to engage smoothly, it can lead to an uncomfortable or even dangerous ride.
How to Avoid This Mistake:
- Ensure that the pedal is not positioned too close to the crank arm, which can limit the freedom of motion.
- Consider adjusting the pedal body position for optimal clearance if necessary.
Conclusion
Proper installation of the Shimano PD-6800 pedals is critical for ensuring both performance and safety. By avoiding common mistakes such as incorrect threading, over-tightening, failing to grease the threads, and misalignment, you can extend the life of your pedals and enjoy a smooth and reliable ride. Always remember to double-check your installation and perform regular maintenance to keep your pedals in top condition.
