The Shimano PD-6700 Ultegra pedals are renowned for their precision engagement, efficient power transfer, and long-term reliability. However, even the most durable pedals require regular maintenance and correct setup to deliver consistent performance. This guide explains how to properly maintain, service, and optimize your PD-6700 pedals so they continue to perform like new for thousands of kilometers.
Tools Required
- 8 mm hex wrench
- 17 mm pedal wrench[paid link] (optional, depending on crank design)
- Shimano TL-PD40 bearing tool (or equivalent)
- Grease syringe or bearing grease gun
- High-quality waterproof grease (Shimano, Park Tool, or similar)
- Torque wrench[paid link]
- Clean rag and degreaser
Understanding the Shimano PD-6700 Pedal System
The Shimano PD-6700 pedal belongs to the Ultegra series and is designed for SPD-SL cleats. It features a wide carbon composite body with stainless-steel plates for durability, along with sealed cartridge bearings for smooth rotation. The adjustable spring tension mechanism allows riders to fine-tune engagement and release to their preference.
Its design focuses on stability, stiffness, and low weight, making it ideal for road cyclists seeking performance and comfort over long rides. However, proper upkeep is essential to prevent issues such as stiffness, creaking, or uneven float.
Installation and Setup Guidelines
Correct installation is the foundation for optimal performance. Before threading the pedals into the crank arms, apply a light coat of grease on the pedal threads to prevent seizing or corrosion. The right pedal tightens clockwise, while the left pedal tightens counterclockwise.
Torque each pedal to approximately 35–40 Nm using a torque wrench[paid link] to ensure secure fitment without damaging the crank threads. Once installed, test for smooth rotation and confirm that the pedal body sits parallel to the ground.
The cleat engagement should feel firm yet responsive. If engagement feels too tight or too loose, adjust the spring tension screw located at the rear of each pedal. Turn the screw clockwise to increase release tension and counterclockwise to decrease it.
Routine Cleaning and Maintenance
Regular cleaning helps prevent dirt and debris from accelerating wear. After every few rides—especially in wet or dusty conditions—wipe the pedal body with a clean rag and mild degreaser.
Pay close attention to the stainless-steel contact plates where the cleats engage. These areas must remain smooth and free of corrosion to ensure consistent engagement and release. Apply a small amount of light grease or dry-film lubricant to these plates to minimize friction and squeaking.
For more comprehensive maintenance, remove the axle assembly every 3,000–5,000 km. Using the Shimano TL-PD40 tool, unscrew the end cap counterclockwise, then carefully extract the axle unit. Clean off old grease and inspect the bearings for wear or contamination. Repack the bearing races with fresh waterproof grease before reassembling.
Servicing the Bearings
The PD-6700 pedals use a cup-and-cone bearing system that can be serviced for extended lifespan. If you notice grinding or resistance when rotating the pedals by hand, it’s time to service the bearings.
Once the axle is removed, clean all parts thoroughly. Check the bearing cones for pitting or discoloration. If any damage is visible, replace the affected components. When reassembling, apply even grease distribution along the bearing path and carefully reinstall the axle assembly.
Shimano recommends tightening the bearing cone just enough to eliminate play but not so much that it causes binding. Once properly adjusted, reinstall the dust cap securely.
Optimizing Pedal Tension and Cleat Fit
Achieving ideal cleat-to-pedal tension ensures smooth engagement without unintended release. Start with a medium setting and adjust based on riding style. Racers often prefer higher tension for secure engagement during sprints, while endurance riders may opt for lighter tension to reduce fatigue.
Ensure your cleats (Shimano SM-SH10[paid link], SH11, or SH12) are in good condition and seated correctly. Worn or deformed cleats can lead to uneven engagement or premature release. Inspect cleat bolts regularly and tighten them to 5–6 Nm as specified by Shimano.
Proper float adjustment is also important. The SH11 cleats provide 6° of float, offering a balance between freedom of movement and knee protection. Riders sensitive to knee alignment can use SH10 (fixed) or SH12 (2° float) cleats for a more direct connection.
Preventing Noise, Play, and Wear
Creaking noises or side play in the PD-6700 pedals often indicate loose bearing cones or dry contact points. Recheck the bearing adjustment and ensure all threads are greased. Lightly lubricate the cleat interface and the cleat bolts themselves.
Avoid over-tightening cleat bolts, as this can distort the shoe sole and cause uneven pressure on the pedal body. Replace the stainless contact plates only when deeply scored, as these surfaces directly influence engagement quality.
For long-term reliability, avoid high-pressure washing directly onto the pedal body. Water intrusion is a common cause of premature bearing wear. Instead, use a gentle brush and controlled rinsing.
Performance Optimization and Longevity Tips
To keep your Shimano PD-6700 pedals running at their best:
- Perform a full cleaning and bearing inspection every 6 months or 5,000 km.
- Use a torque wrench for installation to avoid damaging crank threads.
- Grease the pedal threads and bearings regularly to prevent corrosion.
- Replace worn cleats immediately to preserve engagement consistency.
- Keep spring tension balanced between left and right pedals for symmetrical feel.
Following these steps maintains the original smoothness and stability the PD-6700 pedals are known for, ensuring efficient power transfer and lasting reliability.
Troubleshooting Common Issues
If your pedals feel stiff or noisy, first check the bearing condition. Dry or contaminated grease is the most common cause. If engagement feels inconsistent, inspect cleat wear or spring tension imbalance.
In cases of side play, disassemble the pedal and adjust the bearing cone until the movement disappears. Avoid over-tightening, which can lead to premature wear. If the pedal body creaks during use, apply grease to the cleat interface and re-torque the pedal into the crank arm.
Comparing the PD-6700 with Newer Ultegra Models
While the PD-6700 remains a reliable and high-performing pedal, the newer Shimano PD-R8000[paid link] introduces improved weight reduction and slightly wider platforms. However, both models share identical cleat interfaces and adjustment mechanisms. Riders satisfied with the PD-6700’s engagement feel can confidently continue using it with proper servicing and occasional part replacements.
Final Thoughts
The Shimano PD-6700 Ultegra pedals combine precision, power, and reliability—but only when properly maintained. Routine cleaning, correct bearing adjustment, and periodic servicing are essential to preserving their legendary smoothness. With careful attention to tension balance and cleat alignment, you can enjoy optimal pedal performance for many seasons, keeping your setup running like new.
