The Shimano PD-6700[paid link] pedals, part of the Ultegra series, are a high-performance road pedal system designed for efficiency, stability, and reliability. However, many riders experience performance issues not because of the pedals themselves, but due to improper installation. Even minor errors during setup can lead to poor engagement, creaking noises, or accelerated wear. This guide details the most common Shimano PD-6700 pedal installation mistakes, how to avoid them, and the correct steps to ensure a precise and long-lasting setup.
Understanding the Shimano PD-6700 Pedal Design
Before installation, it’s essential to understand the PD-6700’s design features. These pedals use a wide carbon composite body for improved power transfer and a stainless-steel top plate to reduce flex and wear. The SPD-SL cleat interface provides a stable platform for efficient pedaling, while adjustable entry and release tension allow for customization.
Each pedal is threaded differently:
- The right pedal has a standard right-hand thread (tightens clockwise).
- The left pedal has a reverse (left-hand) thread (tightens counterclockwise).
This distinction is critical to prevent cross-threading—a common cause of crank damage.
Tools Required
- 15 mm pedal wrench[paid link] or 8 mm hex key
- Torque wrench[paid link] (recommended)
- High-quality bicycle grease
- Clean rag
- Degreaser (optional for cleaning old threads)
Mistake 1: Installing Pedals on the Wrong Side
This is one of the most frequent installation errors. Riders often overlook the engraved L and R markings on the pedal axles. Installing the pedals on the incorrect sides can cause immediate cross-threading, damaging the crank arms beyond repair. Always check the labeling before installation, and begin threading each pedal by hand to ensure smooth engagement.
Mistake 2: Ignoring Proper Thread Preparation
Threads must be clean and greased before installation. Failing to apply grease allows corrosion to form between the pedal spindle and the crank arm, making removal nearly impossible later. This can also cause creaking noises during pedaling. Use a degreaser to remove old grease, then apply a thin, even layer of high-quality bicycle grease to the pedal threads before installing.
Mistake 3: Over-Tightening or Under-Tightening the Pedals
Both over-torquing and under-torquing can lead to issues. Over-tightening may strip the crank threads or make removal extremely difficult, while under-tightening can cause the pedal to loosen while riding. The Shimano-recommended torque value for PD-6700 pedals is 35–55 Nm. Use a torque wrench[paid link] whenever possible to ensure accuracy. Hand-tightening is insufficient for long-term security, especially under high pedaling loads.
Mistake 4: Misaligning the Cleats During Installation
Although cleat installation occurs on the shoe, it directly affects pedal performance and rider comfort. Improperly aligned SPD-SL cleats can lead to poor engagement, uneven pedal wear, or knee discomfort. The cleat should be centered under the ball of the foot and aligned with the natural angle of your foot when pedaling. Small misalignments can be amplified through repetitive pedaling, causing joint strain over time.
Mistake 5: Neglecting to Check Crank Arm Thread Condition
Installing pedals into damaged or dirty crank threads can lead to binding or incomplete engagement. Before installation, inspect the threads on both the pedal spindle and crank arm. If there are signs of corrosion or damage, clean them carefully. For heavily damaged threads, consider having a mechanic chase or re-tap them before proceeding. Installing new pedals into compromised threads can ruin both the crank and the pedal.
Mistake 6: Failing to Set Correct Entry and Release Tension
The PD-6700 allows for adjustable tension to control how tightly the cleat engages with the pedal. Many riders overlook this adjustment after installation, leading to premature release or difficulty clipping in. Start with a medium setting, then fine-tune to match your comfort and riding style. Tension should be consistent on both pedals to ensure balanced engagement.
Mistake 7: Not Verifying Smooth Pedal Rotation
After installing the PD-6700 pedals, rotate each one by hand. They should spin freely without resistance or grinding. If stiffness or roughness is felt, the pedal bearings may require servicing before riding. Installing and riding on pedals with dry or contaminated bearings accelerates internal wear and can cause creaking under load.
Mistake 8: Skipping a Post-Installation Check
A post-installation inspection ensures all components are secure and aligned. Spin the cranks and engage each pedal several times with your shoes to confirm smooth entry and release. Check for any movement or noise under pressure. A brief test ride on a flat surface helps detect any issues before a longer ride. After 100–200 km, recheck pedal tightness, as minor settling can occur during early use.
Optimizing Your Shimano PD-6700 Pedal Setup
To maximize performance, pair your PD-6700 pedals with compatible SM-SH11[paid link] yellow cleats, offering six degrees of float for knee protection. Maintain the pedals by cleaning them regularly with a soft brush and applying a light layer of silicone-based lubricant to the cleat interface. Avoid pressure washing or solvent exposure, as these can degrade seals and lubricants inside the pedal body.
Common Symptoms of Poor Installation
Improperly installed Shimano PD-6700 pedals often exhibit these warning signs:
- Creaking or clicking noises during pedaling
- Pedal wobble or lateral play
- Difficulty clipping in or releasing
- Pedal spindle resistance or uneven rotation
- Premature wear on cleats or pedal body
If any of these occur, remove, inspect, and reinstall the pedals using proper torque and lubrication procedures.
Comparing Installation Sensitivity: PD-6700 vs. PD-6800
The Shimano PD-6700 pedals are slightly more sensitive to installation precision than the newer PD-6800 Ultegra model, which uses a stainless-steel insert to reinforce the crank interface. The PD-6700’s aluminum spindle and composite body require careful thread lubrication and correct torque application to prevent seizing or creaking. Riders upgrading from older SPD-SL systems will find that meticulous installation makes a notable difference in smoothness and longevity.
Conclusion
The Shimano PD-6700 pedals deliver efficient power transfer and dependable engagement when installed correctly. Most performance complaints arise not from the design itself but from common installation errors. Paying close attention to correct threading, torque, lubrication, and cleat alignment ensures a trouble-free setup that performs reliably for thousands of kilometers. With proper care and maintenance, your PD-6700 pedals will continue to deliver the precision and performance Shimano’s Ultegra line is known for.
