The Shimano PD-6700[paid link] pedals, part of the Ultegra series, are known for their precision, efficiency, and longevity. However, like all mechanical components, their performance depends heavily on regular maintenance. This guide provides a detailed maintenance plan designed specifically for the PD-6700[paid link] model, helping you preserve pedal performance, prevent premature wear, and maintain consistent engagement over time.
Understanding the Shimano PD-6700 Pedal System
The PD-6700 pedal system uses Shimano’s SPD-SL cleat interface, offering a wide platform and low stack height for optimal power transfer. Constructed with a stainless-steel body plate and a chromoly spindle, these pedals are designed for durability and high-load efficiency. However, the engagement mechanism, spring tension, and bearings require routine servicing to maintain the smooth rotation and reliable clipping action that Shimano pedals are known for.
A consistent maintenance schedule not only extends pedal life but also ensures consistent float, release tension, and safety during high-effort rides.
Recommended Tools Required
- 15mm pedal wrench[paid link] or 8mm hex key
- Shimano TL-PD63 bearing tool
- 10mm hex wrench (for bearing unit removal)
- Waterproof grease (Shimano or equivalent)
- Clean rags and degreaser
- Torque wrench[paid link] (optional, for precise reinstallation)
Routine Cleaning and Inspection
Routine maintenance begins with visual inspection and cleaning. After every few rides, especially in wet or dusty conditions, wipe the pedal body with a clean cloth and mild degreaser. Focus on removing grit from the engagement mechanism and under the retention springs.
Inspect the following areas:
- Cleat contact surfaces: Check for uneven wear or pitting. A worn contact area can reduce engagement security.
- Retention springs: Look for corrosion or loss of spring tension.
- Bearings and spindle: Rotate the pedal by hand. Any grinding, resistance, or side play indicates the need for servicing.
Clean pedals thoroughly and allow them to dry before applying a thin coat of lubricant to the spring mechanism. Avoid over-lubrication, as excess grease can attract debris and accelerate wear.
Bearing Service and Lubrication
The PD-6700 uses a sealed cartridge bearing system with an adjustable cup-and-cone design, making it serviceable with the right tools. Shimano recommends inspecting and regreasing the bearings approximately every 5,000–7,000 kilometers, depending on riding conditions.
Disassembly and Cleaning Process
- Remove the pedal from the crank arm using a 15mm pedal wrench[paid link] or 8mm hex key.
- Using the Shimano TL-PD63 tool, unscrew the bearing unit from the pedal body.
- Clean out old grease and inspect the bearings for contamination or wear.
- Repack the bearings generously with high-quality waterproof grease.
- Reassemble the bearing unit, ensuring smooth rotation without excessive play.
- Reinstall the pedals onto the crank arms, tightening to Shimano’s recommended torque (35–55 Nm).
Consistent lubrication prevents corrosion and ensures efficient power transfer with minimal friction. A well-lubricated bearing set should spin smoothly with a slight resistance but no grinding or lateral movement.
Cleat and Engagement Maintenance
Cleat condition plays a crucial role in pedal performance. The PD-6700 pedals are compatible with SPD-SL cleats, available in yellow (6° float), blue (2° float), and red (0° float). Replace cleats when the engagement surface shows deep grooves or when engagement feels inconsistent.
Periodically check cleat bolts for proper torque (5–6 Nm). Loose cleats can alter engagement feel and cause premature pedal wear. Cleaning cleats and applying a small amount of dry lubricant to the contact points can significantly improve clipping smoothness.
Tension Adjustment and Fine-Tuning
Shimano PD-6700 pedals allow for spring tension adjustment using a 3mm hex key. Over time, spring tension may loosen due to repeated engagement and release cycles. Adjusting the tension ensures consistent release force and prevents accidental disengagement.
Turn the adjustment bolt clockwise to increase release tension and counterclockwise to decrease it. Shimano’s default factory setting suits most riders, but fine-tuning helps match the pedal’s response to personal riding style. After adjustment, engage and disengage your cleats several times to confirm a secure yet smooth release.
Preventing Corrosion and Long-Term Storage Tips
When storing your bike for extended periods, ensure the pedals are clean, dry, and lightly lubricated. Avoid storing the bike in humid environments, as moisture can lead to corrosion within the spindle assembly.
If riding frequently in rain or on salted roads, rinse the pedals with clean water after each ride and reapply lubricant to the spring area. This simple practice prevents rust accumulation and maintains consistent pedal action.
Troubleshooting Common PD-6700 Pedal Wear Symptoms
- Creaking or Clicking Noises: Usually caused by dry threads or loose installation. Remove, clean, grease, and reinstall the pedals.
- Stiff Rotation: Indicates contaminated or dry bearings. Regrease or replace the bearing unit.
- Loose Pedal Feel: Check for spindle play. Re-torque the bearing adjustment nut until the play is eliminated.
- Difficult Cleat Engagement: Could result from worn cleats or clogged contact surfaces. Clean and replace as needed.
Addressing these symptoms promptly prevents long-term damage and ensures continuous performance on demanding rides.
Performance Optimization and Long-Term Maintenance Strategy
To maintain peak performance, create a consistent maintenance schedule. Perform basic cleaning weekly, tension checks monthly, and full bearing service twice a year for regular riders. Competitive cyclists or those riding in wet climates may need more frequent servicing.
Pairing the PD-6700 pedals with Shimano Ultegra or Dura-Ace cleats ensures optimal fit and engagement reliability. Routine cleat replacement, approximately every 3,000–5,000 kilometers, maintains smooth clipping and prevents uneven wear on the pedal body.
A long-term focus on maintenance not only preserves pedal integrity but also enhances rider efficiency and comfort on every ride.
Conclusion
The Shimano PD-6700 pedals are engineered for durability and precision, but consistent maintenance is essential to keep them performing at their best. Regular cleaning, bearing lubrication, and proper tension adjustment ensure these pedals deliver reliable engagement and power transfer for years. With a disciplined maintenance plan, the PD-6700 pedals will remain as smooth and efficient as the day they were installed.
