The Shimano PD-5700[paid link] pedals are part of the 105 series, designed to deliver reliable performance and smooth engagement for road cyclists. However, like any mechanical component, these pedals can develop issues over time. Noisy or stiff PD-5700[paid link] pedals are common symptoms of wear, contamination, or improper setup. This guide explains how to identify the cause and restore your pedals to smooth, silent operation.

Understanding the PD-5700 Pedal Design

The Shimano PD-5700 is a clipless road pedal featuring a stainless-steel body plate, adjustable release tension, and sealed cartridge bearings. It uses Shimano’s SPD-SL cleat interface, which ensures a wide, stable contact area for efficient power transfer.

A smooth rotation and quiet engagement are key performance indicators of a healthy pedal. When noise or stiffness appears, it’s usually caused by contamination in the bearings, worn cleats, or improper lubrication. Understanding the construction helps pinpoint which part may be at fault during maintenance.

Tools Required

  • 8 mm Allen key
  • 17 mm cone wrench[paid link]
  • 10 mm hex wrench
  • Torque wrench[paid link]
  • Shimano pedal axle removal tool (TL-PD63 or equivalent)
  • Waterproof grease (Shimano Dura-Ace or equivalent)
  • Degreaser and cleaning rags

Diagnosing Noisy PD-5700 Pedals

Noise in the PD-5700 pedals can come from three main sources: the cleat interface, the bearings, or the crank-arm threads. Each cause requires a slightly different approach.

1. Cleat Interface Noise

Cleat squeaks or clicks usually occur when the pedal-cleat contact surfaces are dry or contaminated. Check for visible dirt or grit on the stainless-steel contact plate. Clean the surface thoroughly with a degreaser and apply a small amount of dry Teflon or silicone-based lubricant. Also, inspect your SPD-SL cleats for uneven wear or cracks; replace them if worn beyond the indicator lines.

2. Bearing or Axle Noise

Grinding or clicking from within the pedal body usually points to bearing wear or lack of lubrication. Spin the pedal by hand—if it feels rough or produces resistance, the bearings need servicing. Remove the axle assembly using an 8 mm Allen key and Shimano TL-PD63 tool. Clean the internal parts, inspect for rust or pitting, and regrease thoroughly before reassembly.

3. Crank-Arm Interface Noise

Sometimes the noise doesn’t originate from the pedal itself but from the crank threads. Remove the pedal using an 8 mm Allen key, clean both the threads on the pedal spindle and crank arm, apply fresh grease, and reinstall to the recommended torque (35–55 Nm). This step often eliminates creaks that mimic pedal problems.

Diagnosing Stiff PD-5700 Pedals

A stiff or tight-spinning pedal is often a sign of dried grease or corrosion inside the bearing assembly. The PD-5700 uses sealed bearings but still requires periodic service to prevent stiffness.

1. Bearing Inspection

Remove the pedal from the crank. With the Shimano TL-PD63 tool, carefully extract the axle unit. Rotate it by hand. If it feels notchy or tight, disassemble it further to access the bearing cartridge. Clean the bearings and races using a degreaser, then apply a generous amount of waterproof grease.

2. Reassembly and Tension Check

After cleaning, reinstall the axle and tighten the locknut using the 17 mm cone wrench[paid link]. Adjust until the axle spins freely but without lateral play. Over-tightening will cause stiffness, while under-tightening allows wobble. A properly adjusted PD-5700 pedal should rotate smoothly with minimal resistance.

3. Lubrication of Spring Mechanism

Apply a light coat of silicone or PTFE spray to the spring mechanism that controls cleat retention. Avoid using thick grease here, as it attracts debris that can increase stiffness.

Preventing Future Noise and Stiffness

Regular maintenance significantly extends the life of your PD-5700 pedals. Follow these preventive steps:

  • Clean pedal surfaces after every wet or dusty ride.
  • Regrease bearings every 3,000–5,000 km, or sooner in wet climates.
  • Replace cleats annually or when engagement feels loose.
  • Periodically check the tension adjustment bolts to ensure both sides of the pedal offer equal resistance.
  • Avoid pressure washing directly at the bearings to prevent water ingress.

Proper care ensures consistent engagement and minimizes mechanical noise over time.

Optimizing Performance for Smooth Operation

The Shimano PD-5700 pedals can perform close to higher-tier models when properly maintained. Optimizing the release tension according to rider preference enhances comfort and safety. For most riders, a medium setting (approximately halfway between minimum and maximum tension) offers the best compromise between secure retention and easy release.

If you frequently ride in wet conditions, use a slightly thicker grease in the bearing assembly to repel moisture. For competitive riders, consider periodically measuring pedal float and cleat alignment to reduce stress on the knees and maintain efficient pedaling biomechanics.

When to Replace Instead of Repair

While the PD-5700 pedals are serviceable, they have a lifespan. If the bearing races are visibly pitted or the pedal body develops excessive play that cannot be adjusted out, replacement is the best option. Continuing to ride on damaged bearings risks crank-arm thread wear and compromised efficiency.

Additionally, if the spring mechanism loses tension even after adjustment, the internal retention plate may be worn beyond repair. In such cases, a new set of pedals will ensure consistent clipping performance.

Final Inspection Checklist

After servicing your Shimano PD-5700 pedals, perform a quick inspection before your next ride:

  • Pedals spin freely with no grinding.
  • Cleat engagement and release feel consistent.
  • No audible clicks or creaks during rotation.
  • Proper torque applied to crank threads.

Completing these checks guarantees reliable operation and silent, smooth performance on every ride.

Conclusion

Noisy or stiff Shimano PD-5700 pedals are not signs of irreversible damage but rather indicators that maintenance is due. With routine cleaning, proper lubrication, and occasional bearing service, these pedals can deliver thousands of trouble-free kilometers. By following the diagnostic and repair steps outlined above, cyclists can maintain the precise engagement and effortless rotation that define Shimano’s 105-level performance.
