The Shimano PD-6700[paid link] pedals, part of the Ultegra series, are renowned for their balance of low weight, stiffness, and reliability. Designed for performance road cyclists, these SPD-SL pedals provide consistent power transfer and a stable platform for long rides. However, to keep them performing at their best, proper maintenance and periodic adjustment are essential. This guide explains in detail how to maintain, inspect, and service your PD-6700[paid link] pedals for long-term peak performance.
Understanding the Shimano PD-6700 Pedal Design
The PD-6700 pedals are constructed with an aluminum body, stainless steel wear plates, and sealed cartridge bearings. They feature adjustable entry and release tension, which allows riders to fine-tune engagement to their preference. The wide platform distributes load evenly, enhancing comfort and efficiency during pedaling.
Shimano designed these pedals to be low-maintenance, but neglecting cleaning and lubrication can quickly reduce bearing life and engagement precision. Understanding their internal layout and external components is key before attempting any service.
Tools Required
- 15 mm pedal wrench[paid link] or 8 mm hex key
- Small flat-head screwdriver
- Shimano TL-PD40 or compatible pedal axle tool
- Waterproof grease
- Cleaning brush and degreaser
- Torque wrench[paid link] (optional but recommended)
Cleaning and Basic Maintenance
Routine cleaning is vital for extending the lifespan of your PD-6700 pedals. After every few rides—especially in wet or dusty conditions—remove debris and grime to prevent contamination from reaching the bearings.
- Wipe down the pedals using a soft cloth dampened with mild degreaser.
- Clean the cleat contact surfaces thoroughly, paying special attention to the stainless steel plates where the cleats engage.
- Avoid soaking the pedals, as water intrusion can degrade the bearing seals.
- After cleaning, lightly lubricate the spring mechanism and the cleat interface using a thin layer of light oil.
This simple routine helps maintain smooth entry and release while preventing corrosion on metal surfaces.
Bearing Inspection and Lubrication
The PD-6700 uses a sealed cartridge bearing system on each side of the spindle. Although these bearings are designed to be long-lasting, they can develop resistance or play if contaminated or dry.
To inspect and service them:
- Remove the pedal from the crank arm using a 15 mm pedal wrench[paid link].
- Insert the Shimano TL-PD40 tool into the plastic end cap and unscrew it counterclockwise.
- Carefully slide the spindle and bearing assembly out from the pedal body.
- Wipe off old grease and dirt from the spindle and bearing area.
- Apply a fresh coat of waterproof grease to the bearing surfaces and threads.
- Reinsert the spindle assembly, ensuring it seats evenly. Tighten the end cap securely but avoid overtightening.
Perform this procedure every 3,000–5,000 km or sooner if you frequently ride in rain or on salted winter roads.
Spring Tension Adjustment
Proper spring tension adjustment ensures the cleats engage and release smoothly without excessive effort. Each PD-6700 pedal has a small screw near the rear spring for this adjustment.
To fine-tune tension:
- Turn the screw clockwise to increase release tension (for firmer engagement).
- Turn it counterclockwise to reduce tension (for easier release).
For most riders, medium tension offers the best compromise between security and ease of release. Beginners may prefer a looser setting until they are accustomed to clipping in and out.
Regularly check both pedals to confirm that the left and right tensions are balanced, as uneven tension can cause inconsistent engagement during rides.
Cleat Compatibility and Inspection
The PD-6700 pedals are compatible exclusively with Shimano SPD-SL cleats, available in three float options—yellow (6°), blue (2°), and red (0°).
Inspect your cleats regularly for:
- Rounded edges or worn engagement points
- Loose mounting bolts
- Uneven wear on one side
Worn cleats can cause premature pedal wear and unreliable engagement. Replace cleats when engagement feels loose or inconsistent, and always torque the mounting bolts to Shimano’s specification (typically 5–6 Nm).
Troubleshooting Common Issues
Pedal Feels Rough or Stiff
This usually indicates contaminated or dry bearings. A full bearing service and regreasing should restore smooth operation.
Difficulty Clipping In or Out
Inspect both the cleats and pedal engagement surfaces for wear or dirt. Clean and lubricate the mechanism, then adjust spring tension slightly looser.
Lateral Play or Loose Feeling
Check for end cap tightness and bearing wear. If the spindle assembly moves excessively, rebuild the pedal or replace the internal cartridge.
Creaking Noises
Creaks often come from dry pedal threads or loose installation. Remove the pedals, apply a thin coat of grease to the threads, and reinstall to the manufacturer’s torque specification (typically 35–40 Nm).
Optimizing Pedal Performance
For consistent performance, develop a preventive maintenance schedule. Clean the pedals weekly, inspect cleats monthly, and service bearings at least once per season. Use high-quality grease and ensure the spring tension suits your riding style.
If you’re racing or training intensively, upgrading to stainless steel or titanium spindles (compatible aftermarket options exist) can reduce weight while maintaining the same SPD-SL interface.
Proper lubrication and timely adjustments not only enhance pedaling efficiency but also prevent mechanical failure during demanding rides.
Comparison: PD-6700 vs. PD-6800
The Shimano PD-6800, Ultegra’s next-generation pedal, features a slightly larger platform and improved bearing seals, but its core design remains similar to the PD-6700. Riders upgrading from PD-6700 will notice marginally better weather resistance and smoother engagement, though the performance gap is minor.
For most cyclists, maintaining PD-6700 pedals correctly will deliver near-identical performance to newer models, making them an excellent long-term choice.
Conclusion
Proper maintenance of your Shimano PD-6700 pedals ensures longevity, smooth engagement, and optimal power transfer. Regular cleaning, timely bearing service, and precise spring tension adjustment will keep your pedals performing as they did on the first ride. By following the steps outlined in this guide, you’ll not only extend their lifespan but also enjoy a more efficient and reliable pedaling experience on every ride.
