The Shimano PD-5700[paid link] pedals are a staple in the Shimano 105 series, designed for serious road cyclists who value durability, smooth engagement, and efficient power transfer. However, even reliable components like the PD-5700 can develop issues over time due to wear, contamination, or improper setup. This guide covers the most common pedal problems specific to the PD-5700 model and provides detailed, technical solutions to restore optimal performance.
Tools Required
- 8 mm hex wrench
- Pedal wrench[paid link] (if applicable)
- Torque wrench[paid link]
- Bearing grease (Shimano-approved)
- Clean rag or paper towels
- Degreaser or isopropyl alcohol
- Small brush or old toothbrush
- 10 mm and 15 mm cone wrenches (for bearing service)
Understanding the Shimano PD-5700 Pedal Design
The PD-5700 pedals use Shimano’s SPD-SL cleat system, offering a wide platform for efficient power transfer. They feature a chromoly spindle, sealed cartridge bearings, and adjustable release tension. Their low-maintenance design is meant to withstand high mileage, but as with all mechanical parts, they are subject to wear and require periodic inspection.
Loose Pedal Body or Excessive Play
A common issue with the PD-5700 pedals is excessive lateral play between the pedal body and spindle. This occurs when the internal bearings loosen over time or lose lubrication.
Solution:
Remove the pedal body from the spindle assembly using the correct cone wrenches. Clean the internal components thoroughly, inspect the bearings for wear, and apply fresh grease. Adjust bearing tension carefully—too tight will restrict rotation, too loose will cause play. Reassemble and check for smooth, wobble-free rotation.
Regular bearing service every 5,000–8,000 km prevents premature wear and helps maintain consistent engagement.
Creaking or Clicking Noises
Creaking noises under load are another frequent complaint. These sounds can originate from the pedal threads, spindle, or cleat interface.
Solution:
First, remove and clean the pedal threads on both crank arms. Apply a thin layer of anti-seize compound or grease before reinstalling. Torque to Shimano’s recommended 35–40 Nm.
If the noise persists, inspect cleat bolts and ensure they are torqued evenly. Worn-out cleats can also cause uneven contact with the pedal body, resulting in clicking noises during pedaling. Replacing cleats when wear indicators disappear restores silent operation.
Difficulty Clipping In or Out
Cyclists sometimes report difficulty engaging or releasing from PD-5700 pedals, particularly if spring tension is misadjusted or if dirt and grime accumulate around the binding mechanism.
Solution:
Clean the pedal binding areas thoroughly with a brush and degreaser. Avoid using thick lubricants that attract debris; instead, apply a light silicone-based lubricant to the moving parts.
Next, inspect the tension adjustment bolts located on the rear of each pedal. Using a 3 mm hex wrench, turn clockwise to increase release tension or counterclockwise to decrease it. Set both pedals to identical tension for consistent engagement feel.
Uneven or Stiff Rotation
When the pedal spins unevenly or feels stiff, this typically indicates contamination inside the bearing assembly. Road grime, moisture, or old grease can restrict smooth rotation.
Solution:
Disassemble the spindle assembly following Shimano’s technical service instructions. Remove all old grease and debris, and inspect the bearing balls and races. Replace any corroded or pitted parts.
Repack the bearings with high-quality Shimano or equivalent waterproof grease. Ensure the seal is correctly seated before reassembly to maintain proper resistance against contamination.
Pedal Not Returning to Horizontal Position
The PD-5700 is designed to self-level due to its weighted rear section, making clipping in easier. If the pedal fails to return to a horizontal position, debris or corrosion in the spring mechanism is often the cause.
Solution:
Clean around the spring pivot points with a degreaser and compressed air. Apply a very small amount of dry lubricant to the spring assembly. Do not over-lubricate, as excess oil can attract dirt and slow the return motion.
Cleat Wear and Misalignment
Worn or misaligned cleats can cause inconsistent release and poor engagement, leading to knee discomfort and reduced pedaling efficiency. The PD-5700 is designed for use with Shimano SPD-SL cleats, available in three float options: yellow (6°), blue (2°), and red (0°).
Solution:
Inspect the cleats regularly for visible wear, particularly around the engagement tabs. Replace cleats before they become rounded or excessively worn. When installing new cleats, ensure symmetrical positioning and use a marker to outline their alignment for future reference.
Bearing Leakage or Contaminated Grease
If you notice dark grease seeping from the pedal spindle area, it indicates that contaminants have entered the bearing system. Continued use without servicing will result in grinding and long-term damage.
Solution:
Disassemble the pedal and clean all bearing components. Replace damaged seals if necessary. Apply fresh grease liberally to the bearings and reinstall the end cap tightly. Always check that the dust seal sits flush against the body to maintain a proper barrier against moisture.
Pedal Thread Damage
Cross-threading or over-tightening during installation can damage the crank arm threads or the pedal spindle threads, leading to unsafe installation and possible crank failure.
Solution:
Inspect the crank arm threads for signs of wear before installation. Always hand-thread the pedal first to ensure proper alignment. Use a torque wrench[paid link] to tighten within specification. If threads are already damaged, consider using a pedal thread repair kit or replacing the crank arm entirely.
Maintaining Peak Performance
To keep the Shimano PD-5700 pedals in top condition, clean them after every few rides, especially in wet or gritty environments. Avoid pressure washing, as it can force water into the bearings. Periodically check for smooth spindle rotation, and re-grease at least twice a season for high-mileage riders.
For best performance, pair the PD-5700 pedals with Shimano 105 or Ultegra-level cleats and cranks. Proper maintenance not only extends the pedal’s lifespan but also ensures efficient power transfer and comfort on long rides.
Troubleshooting Summary
| Issue | Likely Cause | Recommended Fix |
|---|---|---|
| Lateral play | Loose bearings | Re-grease and adjust bearing preload |
| Creaking noise | Dry threads or worn cleats | Clean, lubricate, and torque properly |
| Hard to clip in/out | High tension or debris | Clean and adjust tension screws |
| Stiff rotation | Contaminated bearings | Disassemble, clean, re-grease |
| Poor self-leveling | Dirty spring pivot | Clean and apply dry lube[paid link] |
| Pedal thread damage | Cross-threading | Use correct installation torque |
Conclusion
The Shimano PD-5700 pedals remain a dependable choice for road cyclists seeking consistent engagement, light weight, and long-term durability. Most issues—such as creaks, stiffness, or engagement difficulty—stem from neglect or improper setup rather than design flaws. Regular servicing, correct tension adjustment, and mindful installation will ensure these pedals continue to perform flawlessly for many seasons.
