The Shimano PD-5700[paid link] pedals, part of the 105 series, are renowned for their reliability and consistent engagement performance. However, even the most precise clipless pedals require careful tension adjustment to ensure both comfort and safety on the road. Improperly adjusted spring tension can lead to either unintentional release or difficulty disengaging from the pedal, both of which compromise ride control. This guide explains how to correctly adjust, test, and maintain the tension settings on your Shimano PD-5700[paid link] pedals to achieve optimal performance.
Tools Required
- 3 mm Allen key
- Torque wrench[paid link] (optional but recommended)
- Workstand or stable bike support
- Clean rag and degreaser
- Grease or light lubricant
Understanding the PD-5700 Tension Mechanism
The Shimano PD-5700 uses a spring-loaded retention system to secure the cleat into the pedal body. This system allows the rider to adjust the release tension, controlling how much force is needed to disengage the cleat. The adjustment screw, located at the rear of each pedal, tightens or loosens the spring tension.
Turning the screw clockwise increases release tension, making it harder to unclip. Turning it counterclockwise decreases tension, making release easier. Shimano’s design includes an adjustment range marked by small indicator lines visible beside the screw, allowing you to balance both pedals equally.
Preparation Before Adjustment
Before beginning the adjustment process, ensure the pedals and cleats are clean and free from debris. Dirt and grease buildup can interfere with proper engagement and mask the true feel of the tension settings. Wipe down both pedals with a degreaser, and if necessary, apply a light lubricant to the moving parts around the retention mechanism. Make sure the bike is stable on a stand to safely rotate the cranks during testing.
Adjusting the Tension
To adjust tension on the Shimano PD-5700 pedals, locate the small 3 mm hex screw on the back of each pedal. This screw directly controls the spring preload that determines release tension.
Start with both pedals set to the minimum tension by turning the screw counterclockwise until resistance is felt. From there, incrementally tighten (clockwise) by one-quarter turn per adjustment. After each adjustment, clip in and out to test the feel.
The goal is to achieve a balance where clipping in feels firm but not forced, and unclipping is predictable without sudden or overly tight resistance. It is critical to match the tension on both pedals for symmetrical engagement during rides. Shimano recommends using the indicator marks as a visual guide to ensure both pedals have similar settings.
Testing Engagement and Release
Once adjusted, test the pedals on a stationary trainer or while leaning against a wall. Clip in with your dominant foot first, then the other, checking for uniform resistance and secure engagement. Twist your heel outward to release. The motion should feel smooth and consistent on both sides.
If you experience difficulty releasing, reduce tension slightly. Conversely, if the cleats disengage too easily or feel loose during hard efforts, increase the tension. It is advisable to make small adjustments and re-test, as overtightening the spring can lead to premature wear of both the cleat and pedal mechanism.
Fine-Tuning for Riding Conditions
The ideal release tension varies depending on rider preference, cleat wear, and riding conditions. For new riders, a lower tension setting offers safer and more manageable engagement, allowing easy disengagement in unexpected stops. For competitive riders or those tackling high-speed descents, higher tension ensures better stability and prevents accidental release under heavy torque.
Over time, cleats wear and the release feel can change. Regularly check and readjust tension to compensate for this wear. A good practice is to inspect tension monthly or every 500–700 km of riding, especially if you ride in wet or muddy conditions that may affect the mechanism.
Troubleshooting Common Tension Issues
If your Shimano PD-5700 pedals do not respond to adjustment, check for dirt accumulation or corrosion inside the spring area. Stiff tension screws often indicate lack of lubrication. Apply a drop of light oil directly to the screw threads and pivot points, then work the mechanism by turning the screw several times.
If tension feels inconsistent between pedals even after adjustment, inspect the spring assembly for wear or cracks. In such cases, replacing the pedal body or retention spring may be necessary to restore proper functionality.
Persistent uneven tension or loose engagement could also be caused by worn-out cleats. Shimano recommends replacing cleats once the engagement edges become rounded or the indicator lines are no longer visible.
Maintenance and Longevity
To maintain consistent tension performance, clean and lubricate your PD-5700 pedals every few weeks, particularly after wet rides. Avoid over-lubrication, which can attract grit and shorten the life of the retention spring. Periodic bearing service is also essential to prevent internal friction that can alter pedal feel.
When reinstalling pedals after service, ensure they are torqued to the correct specification—typically 35–40 Nm—for secure attachment without over-tightening the crank threads.
Conclusion
Proper tension adjustment on the Shimano PD-5700 pedals enhances safety, comfort, and pedaling efficiency. By carefully tuning the release tension, riders can achieve a personalized setup that suits their riding style and skill level[paid link]. Regular maintenance and fine-tuning ensure the pedals continue to perform smoothly for years, preserving the dependable engagement that defines Shimano’s 105-series components.
