The Shimano PD-5700 pedals, part of the 105 series, are known for their reliable engagement, smooth rotation, and efficient power transfer. However, even a well-engineered pedal system can experience issues over time due to wear, dirt buildup, or incorrect setup. This guide explains how to diagnose and fix the most common engagement problems affecting the PD-5700 pedals, ensuring smooth clipping, firm retention, and optimal pedaling performance.
Understanding the Shimano PD-5700 Pedal System
The PD-5700 pedal operates using Shimano’s SPD-SL clip-in mechanism, which is designed to offer a wide platform for stability and a firm cleat interface for efficient power transfer. It relies on a tension-adjustable spring system that secures the cleat (typically Shimano SM-SH11, SH12, or SH10) to the retention mechanism.
When set up correctly, the pedal should provide consistent entry and release, minimal lateral play, and a quiet, solid feel underfoot. Engagement problems typically arise from incorrect tension settings, contaminated contact points, worn cleats, or dry pivot mechanisms.
Tools Required
- 4 mm hex wrench
- 15 mm pedal wrench[paid link] (optional, for removal)
- Degreaser
- Light grease or pedal-specific lubricant
- Clean rags
- Torque wrench[paid link]
Identifying Common PD-5700 Engagement Problems
1. Difficult Clip-In or Inconsistent Engagement
If clipping in feels stiff, inconsistent, or requires excessive force, the tension spring or cleat interface may be at fault. This issue often appears after long use or when dirt and grime build up around the engagement mechanism.
The most common causes include:
- Excessive release tension settings.
- Dirty or dry spring pivots.
- Worn or damaged cleats.
- Debris lodged under the retention plate.
2. Loose or Unstable Engagement
If the cleat feels wobbly after clipping in, it indicates wear on either the pedal retention surface or the cleat contact area. Shimano SPD-SL pedals rely on a tight mechanical fit, and even slight wear can cause movement that affects stability and power transfer.
Contributing factors include:
- Worn cleats, especially along the yellow rubber pads (for SH11).
- Flattened or scratched retention plates.
- Loose pedal body or worn bearings causing lateral play.
3. Difficulty Releasing the Cleat
A common problem arises when the cleat does not disengage smoothly, especially when twisting the heel outward. This can result from either a high release tension setting or contamination around the spring mechanism.
In some cases, corrosion or dried lubricant can cause the retention plate to stick, requiring cleaning and re-lubrication.
Step-by-Step Troubleshooting and Fixes
Cleaning the Engagement Mechanism
- Remove the pedals from the crank using a 15 mm pedal wrench[paid link] if necessary.
- Apply degreaser around the spring mechanism, contact plates, and pivot points.
- Use a brush to loosen any compacted dirt or grit.
- Wipe thoroughly with a clean rag and inspect for corrosion or visible wear.
- Apply a small amount of light grease or silicone-based lubricant to the spring and pivot joints.
Regular cleaning maintains crisp engagement and prevents sticking or uneven tension.
Adjusting the Spring Tension
The Shimano PD-5700 features a spring tension adjustment screw located at the rear of the pedal body.
- Use a 4 mm hex wrench to rotate the screw clockwise to increase tension or counterclockwise to decrease it.
- Begin with a lower tension setting for easy entry and release, then increase gradually to match your riding style.
- Check both pedals to ensure the settings are balanced.
Proper tension adjustment prevents accidental release while ensuring comfortable engagement and disengagement.
Inspecting and Replacing Worn Cleats
Cleats wear faster than pedals and are often the root cause of poor engagement. Examine the cleats for visible rounding of the engagement edges, especially on the front lip and side flanges.
If cleats appear shiny, rounded, or cracked, replace them immediately. Worn cleats can compromise retention and accelerate pedal wear. Always torque cleat bolts to 5–6 Nm and ensure they are evenly tightened.
Checking Bearing Play and Pedal Body Wear
If you notice excessive movement when the shoe is clipped in, the pedal bearings may need servicing. Hold the pedal body and spindle; any noticeable side-to-side movement indicates wear or looseness.
The PD-5700 uses Shimano’s serviceable cup-and-cone bearing system. Servicing involves removing the end cap, adjusting the cone, and re-greasing the bearings. Proper bearing adjustment ensures smooth rotation and eliminates unwanted lateral play that can mimic engagement looseness.
Preventative Maintenance Tips
Keeping PD-5700 pedals in good condition minimizes engagement problems and extends their lifespan.
- Clean pedals regularly, especially after wet rides.
- Apply a drop of lubricant to the spring mechanism every few weeks.
- Inspect cleats every 2,000–3,000 km and replace when necessary.
- Check for even wear on both pedals; differences can indicate misalignment or uneven riding habits.
- Avoid pressure-washing pedals directly, as it can push water into the bearing assembly.
Optimizing Engagement Feel
Fine-tuning the PD-5700 for your riding style improves control and comfort. Sprinters and competitive riders often prefer firmer tension for security during sprints, while endurance riders benefit from a slightly looser setting for easy dismounts.
Additionally, ensuring your cleats are precisely aligned with your natural foot angle reduces stress on the knees and enhances overall engagement feel.
Comparison Insight: PD-5700 vs. PD-R7000
The PD-R7000[paid link] (the 105 series successor) features a wider carbon composite body and improved bearing seals compared to the PD-5700. Riders upgrading to PD-R7000[paid link] can expect slightly smoother rotation and better water resistance. However, engagement feel remains nearly identical, and cleat compatibility is fully interchangeable between both models.
This makes the PD-5700 still a viable and reliable choice for riders seeking performance on a budget without sacrificing functionality.
Conclusion
The Shimano PD-5700 pedals offer reliable performance when properly maintained and adjusted. Most engagement problems stem from neglected cleaning, worn cleats, or misadjusted tension settings. By following regular maintenance routines and fine-tuning engagement tension, riders can keep their PD-5700 pedals performing smoothly for many thousands of kilometers.
Consistent attention to detail ensures precise clipping, effortless release, and long-term reliability—a hallmark of Shimano’s SPD-SL system.
