The Shimano PD-5700[paid link] pedals, part of the 105 series, remain a trusted mid-range option for many road cyclists seeking reliable performance without the premium price tag. However, as cycling technology evolves, many riders wonder whether their PD-5700[paid link] pedals can be upgraded or optimized to deliver better efficiency, smoother engagement, or improved compatibility with modern drivetrains. This guide explores all aspects of upgrading the Shimano PD-5700 pedals, from bearing replacement to cleat compatibility, ensuring every rider can make informed maintenance and upgrade decisions.
Understanding the Shimano PD-5700 Pedal Design
The Shimano PD-5700 pedals use the SPD-SL clipless system, offering wide contact area, stable power transfer, and durable chromoly spindles. They were engineered for the 10-speed Shimano 105 drivetrain group but remain compatible with a range of cranksets and cleats. The design is minimalist and serviceable, allowing users to maintain and customize their pedals for specific riding styles or performance goals.
Each pedal features:
- A wide carbon-reinforced resin body for stiffness and low weight.
- Adjustable release tension for customized engagement.
- Durable sealed cartridge bearings for long-lasting smooth rotation.
- Standard 9/16″ threads compatible with most crank arms.
These characteristics make the PD-5700 both durable and upgrade-friendly when maintained correctly.
Assessing Upgrade Possibilities
When upgrading Shimano PD-5700 pedals, the goal is typically to improve performance, reduce weight, or enhance pedaling feel. While the pedal body itself cannot be substantially upgraded, several surrounding components and internal elements can be replaced or improved.
Bearing and Axle Upgrades
Over time, the PD-5700’s cartridge bearings may lose smoothness or develop play. Replacing them with high-quality aftermarket bearings can restore or even improve the original feel. Shimano’s official bearing replacement kit for PD-5700 remains available through service centers, though compatible third-party options such as ceramic hybrid bearings can reduce rolling resistance and increase longevity.
The chromoly axle is robust and corrosion-resistant. However, for riders seeking marginal gains, upgrading to titanium axles from reputable aftermarket manufacturers can reduce overall pedal weight by 40–60 grams per pair. It’s essential to ensure the replacement axle matches the Shimano thread specifications and spindle length to maintain Q-factor consistency.
Cleat Compatibility and Upgrade Options
The PD-5700 pedals use the SPD-SL cleat interface, meaning they are compatible with all SPD-SL cleats (SH10, SH11, SH12). Each cleat type provides a different level of float—zero, two, or six degrees—allowing riders to fine-tune comfort and alignment.
Upgrading to the SH12 blue cleats can improve knee alignment and efficiency for experienced riders who prefer a tighter connection, while the SH11 yellow cleats are ideal for beginners and endurance cyclists who need more float to prevent strain.
Cleat maintenance and replacement significantly influence pedal performance. Worn or damaged cleats can cause poor engagement and unwanted play, making timely replacement an important part of pedal upkeep.
Comparing Upgrade Options Within Shimano’s Line-Up
Cyclists considering performance upgrades may evaluate whether upgrading to a newer pedal model is more beneficial than modifying the PD-5700.
- PD-5800 (105 11-speed): Slightly lighter with improved bearing seals and enhanced pedal body stiffness.
- PD-R7000[paid link] (current 105): Offers the best balance between durability, weight, and cost with stainless steel body plates for improved wear resistance.
- PD-R8000[paid link] (Ultegra): Incorporates a carbon composite body, lower stack height, and a wider platform for better power transfer.
- PD-R9100[paid link] (Dura-Ace): Shimano’s lightest and most precise option, ideal for competitive riders seeking maximum stiffness and minimal weight.
While these newer models offer incremental improvements, the PD-5700 remains compatible with all current SPD-SL cleats, making it a viable long-term option if properly maintained and serviced.
Maintenance Practices to Support Upgrades
Before pursuing upgrades, ensure that your PD-5700 pedals are in optimal working condition. Regular maintenance can significantly extend their service life and sustain performance improvements gained through upgrades.
- Clean the pedal body after every few rides to prevent grit buildup around the engagement mechanism.
- Inspect the bearings periodically for smooth rotation. Repack or replace them when roughness develops.
- Check the cleat bolts regularly to ensure they remain tight and properly aligned.
- Lubricate the spring mechanism and threads lightly during service intervals to prevent corrosion.
Maintaining a clean, well-lubricated pedal body ensures smoother clipping in and out, more consistent tension, and reduced wear on cleats.
Customization and Tuning for Better Performance
The PD-5700 offers a range of small adjustments to fine-tune its feel. Adjusting the spring tension screw can significantly affect engagement ease and stability. Cyclists who prefer a firmer connection can tighten the tension slightly, while beginners or riders using softer shoes may benefit from a lighter setting.
Pedal washers can also be added between the crank arm and pedal spindle to slightly modify the Q-factor for better knee alignment. These small adjustments can reduce discomfort on longer rides and improve pedaling efficiency without needing to switch pedal models.
Compatibility Considerations with Modern Drivetrains
The PD-5700 pedals are compatible with all Shimano road cranksets using a standard 9/16″ thread interface, including 11- and 12-speed drivetrains. The SPD-SL system has maintained cross-generational compatibility, meaning the PD-5700 can be used on current Shimano groupsets, from 105 to Dura-Ace, as well as on cranksets from FSA, Praxis, and Rotor.
However, riders using gravel or mixed-terrain setups may find SPD (two-bolt) systems more convenient due to easier walking and mud clearance. In such cases, upgrading to an SPD-compatible system like the PD-ES600 may be more practical.
Conclusion
Upgrading Shimano PD-5700 pedals is both feasible and worthwhile for riders who value durability and efficiency. While the body design itself remains unchanged, replacing bearings, adjusting cleats, or installing lightweight axles can yield tangible improvements in performance and feel.
The PD-5700’s continued compatibility with modern SPD-SL cleats ensures long-term usability, making it a smart foundation for cyclists who prefer to upgrade components incrementally rather than replace entire systems. With proper maintenance, these pedals can perform at a near-modern standard—proof of Shimano’s enduring design philosophy and the PD-5700’s lasting value to dedicated road cyclists.
