Maintaining your Shimano SM-SH12 [paid link] pedals is essential for ensuring smooth, efficient performance over time. Proper lubrication and cleaning help protect the internal mechanisms, maintain smooth pedal engagement, and prolong the lifespan of your pedals. In this guide, we will cover the best practices for cleaning and lubricating your Shimano SM-SH12 [paid link] pedals to keep them functioning at their best.

Why Proper Lubrication and Cleaning Matters

Your Shimano SM-SH12 pedals experience constant friction and exposure to the elements. As a result, they are prone to accumulating dirt, debris, and moisture, which can cause wear and tear on moving parts. Over time, this buildup can lead to stiff engagement, noisy performance, or even premature failure of the pedal bearings. Regular cleaning and lubrication prevent this, ensuring smooth engagement, reduced wear, and improved durability.

Tools Required

Before you start, ensure you have the following tools:

  • Pedal wrench [paid link] or a 15mm spanner
  • Soft cloth or rag
  • Chain cleaning brush or small detailing brush
  • Degreaser
  • Bike-specific lubricant (preferably for pedals or metal components)
  • Cotton swabs (for hard-to-reach areas)
  • Water-resistant grease
  • Small container for soaking parts (optional)

Cleaning Your Shimano SM-SH12 Pedals

1. Remove the Pedals:

  • Use a pedal wrench [paid link] or 15mm spanner to carefully remove the Shimano SM-SH12 pedals from the crankset.
  • Turn the wrench counterclockwise to loosen the pedals. Remember, the left pedal is reverse-threaded, so you’ll need to turn it clockwise to remove it.
  • Set the pedals aside on a clean surface.

2. Clean the Pedal Bodies:

  • Using a soft cloth or rag, wipe down the body of the pedal to remove any visible dirt or grime.
  • If there is stubborn dirt, use a small chain cleaning brush or detailing brush to scrub it off gently. Be careful not to scratch the surface of the pedal body.

3. Clean the Cleat Mechanism:

  • The Shimano SM-SH12 pedals feature a cleat retention mechanism that can accumulate dirt. Use a cotton swab or small brush to clean around the spring mechanism and the cleat interface.
  • Be thorough in removing debris from the engagement area to prevent stiffness or poor cleat engagement.

4. Rinse and Dry:

  • Lightly rinse the pedals with water to remove any remaining degreaser or cleaning solution.
  • Dry the pedals completely using a clean cloth. Ensuring they are fully dry before proceeding to the next steps is essential to prevent moisture buildup.

Lubricating Your Shimano SM-SH12 Pedals

1. Apply Grease to the Pedal Axles:

  • For smooth pedal rotation and to prevent rusting, apply a thin layer of waterproof grease to the pedal axles. This helps to maintain smooth movement within the pedal bearings.
  • Use your fingers or a small brush to evenly coat the pedal axles with grease. Ensure you apply grease on both sides of the axle to reduce friction and water ingress.

2. Lubricate the Cleat Mechanism:

  • Apply a small drop of lubricant to the spring mechanism. This ensures smooth engagement and release of the cleat.
  • Avoid over-lubricating, as excessive lubricant can attract dirt and grime, which could affect performance.

3. Check for Proper Lubrication and Movement:

  • After applying lubricant, manually rotate the pedal to check for smoothness. If the movement feels stiff, you may need to reapply grease or check for dirt buildup inside the pedal axle.

Preventative Maintenance Tips

1. Regularly Inspect for Wear:

  • Periodically check your Shimano SM-SH12 pedals for signs of wear, especially around the pedal axles and spring mechanism. Look for cracks, rust, or excessive play that may indicate the need for repairs or replacement.

2. Avoid Over-Lubricating:

  • While lubrication is essential, avoid using too much lubricant as it can attract dust and grime, which could negatively affect pedal performance. A thin layer is often sufficient.

3. Protect from the Elements:

  • When riding in wet or muddy conditions, clean and dry your pedals as soon as possible after each ride. This prevents mud and water from entering the pedal mechanism and causing damage over time.

4. Reapply Grease Periodically:

  • For optimal performance, it’s a good idea to clean and reapply grease to the pedal axles every few months, depending on the conditions you ride in. Frequent cleaning and lubrication extend the life of your pedals and maintain consistent performance.

Conclusion

Proper cleaning and lubrication of your Shimano SM-SH12 pedals are crucial for maintaining their performance, durability, and longevity. By regularly cleaning your pedals, applying the right amount of lubrication, and following the preventative maintenance tips provided, you can ensure your pedals perform optimally for years. Regular maintenance not only protects your investment but also contributes to a smoother, more enjoyable riding experience.
