The Shimano PD-5700[paid link] pedals—part of Shimano’s 105 series—are well-known for their efficient power transfer, smooth engagement, and reliable performance. However, to ensure they continue performing at their best, regular maintenance and inspection are essential. This guide provides a comprehensive, technical overview of maintaining the Shimano PD-5700[paid link] pedals, including cleaning, lubrication, bearing servicing, and adjustment procedures.
Understanding the Shimano PD-5700 Pedal System
The Shimano PD-5700 is a road clipless pedal designed for use with SPD-SL cleats. Its wide platform provides excellent stability, while the adjustable release tension caters to both competitive and recreational riders. The sealed cartridge bearing system ensures smooth rotation and long-lasting durability when properly maintained.
Unlike more recent models, the PD-5700 does not feature a fully serviceable bearing cartridge, but regular cleaning and lubrication can significantly extend its operational life. Ensuring correct cleat engagement and tension settings will also prevent premature wear on both pedal and shoe interface components.
Tools Required
Before beginning maintenance, gather the following tools and materials:
- 15 mm pedal wrench[paid link] or 8 mm hex key
- Shimano TL-PD40 pedal axle tool (optional for deeper servicing)
- Degreaser and mild detergent
- Clean rags and brushes
- Waterproof bicycle grease
- Torque wrench[paid link]
- Light oil (e.g., Shimano PTFE-based lubricant)
Routine Cleaning and Inspection
Regular cleaning is vital to maintain the efficiency and lifespan of the PD-5700 pedals. Dirt, grit, and moisture can lead to corrosion and bearing wear over time.
Start by removing the pedals from the crank arms using a 15 mm pedal wrench[paid link] or an 8 mm hex key, depending on your crank design. Clean the pedal body thoroughly using a mild detergent and soft brush to remove road grime and debris. Avoid harsh chemicals that can degrade the pedal’s resin body or damage the bearing seals.
After cleaning, dry the pedals completely before reassembly. A light coating of lubricant on the engagement mechanisms will ensure smooth entry and release. Make sure not to over-apply oil—excess lubricant can attract more dirt, leading to faster wear.
Inspect the contact area between the cleat and pedal body for signs of pitting, gouging, or plastic deformation. Minor surface wear is normal, but deep scoring indicates the need for replacement. Also, verify that the tension adjustment screw is responsive and moves freely through its range.
Bearing Maintenance and Lubrication
The PD-5700 features sealed bearings designed for longevity. However, the grease inside these bearings gradually breaks down with use and environmental exposure. Periodically re-lubricating the bearing system will prevent premature friction and improve pedal rotation smoothness.
If the pedal feels rough when spun by hand, it’s time for internal servicing. Using the Shimano TL-PD40 tool, unscrew the axle assembly counterclockwise. Carefully withdraw the axle unit and wipe away old grease. Avoid disassembling the internal bearing stack unless necessary, as this can lead to misalignment during reassembly.
Repack the bearing surfaces with a high-quality waterproof grease, ensuring even distribution. Slide the axle back into the pedal body and torque to the manufacturer’s specification (typically 34–36 Nm). Once reinstalled, rotate the pedal several times to evenly distribute the grease and confirm free movement.
Tension Adjustment for Optimal Performance
Proper engagement tension is essential for efficient pedaling and safety. The PD-5700 allows for micro-adjustments using a 3 mm Allen key on the rear tension screw.
For new riders or those using soft-soled shoes, a lighter release tension provides easier disengagement. More experienced cyclists who sprint or climb aggressively may prefer higher tension for a secure connection.
Adjust both pedals evenly to maintain balanced engagement. To test, clip in and out several times while the bike is stationary, ensuring the cleats release predictably without excessive force. Recheck the adjustment after your first few rides to confirm stability.
Preventing Corrosion and Long-Term Wear
Moisture and road contaminants are the main enemies of pedal longevity. After wet rides, wipe down the pedals and apply a light coat of PTFE-based lubricant to the spring mechanisms. Do not allow water to remain pooled around the axle seals.
Store your bicycle indoors when possible. If outdoor storage is unavoidable, consider using a protective cover and periodically greasing the pedal threads to prevent galvanic corrosion between the crank arm and pedal spindle.
Regular cleat inspection is also important. Worn or uneven cleats can damage the pedal’s binding surfaces and increase the risk of accidental release. Replace SPD-SL cleats once they show significant wear on the front or rear contact points.
Troubleshooting Common Issues
If the pedal feels stiff or gritty, the bearings likely need cleaning and re-greasing. Grinding sensations usually indicate contamination. For loose or wobbly rotation, the axle locknut may have loosened and should be re-torqued to spec.
Difficulty clipping in or out often results from dirt accumulation around the retention mechanism or overly high tension settings. Clean and lubricate the binding springs and lower the tension gradually until engagement feels smooth.
If one pedal feels different from the other, verify that both are adjusted equally and that cleats are mounted symmetrically on the shoes.
Optimizing Pedal Performance
Maintaining your Shimano PD-5700 pedals is not only about extending their lifespan but also about preserving consistent pedaling efficiency. Proper lubrication and adjustment minimize power loss, reduce fatigue, and improve overall comfort.
Pairing your PD-5700 pedals with genuine SPD-SL cleats ensures correct fit and function. Avoid using third-party cleats, as minor dimensional differences can compromise release performance and cause premature wear on the pedal interface.
For enhanced durability, periodically rotate the pedals between bikes if you use multiple setups. This allows for even wear distribution and more consistent feel across your rides.
Conclusion
The Shimano PD-5700 pedals are a durable and efficient choice for road cyclists who value consistent engagement and smooth pedaling mechanics. By following a regular maintenance routine—cleaning, lubrication, tension adjustment, and inspection—you can ensure optimal performance and extend the lifespan of your pedals. Proper care not only keeps your PD-5700 pedals running like new but also safeguards the efficiency and safety of every ride.
