The Shimano SM-SH12 [paid link] pedals are a top choice for road cyclists who prioritize performance, comfort, and durability. These pedals offer a solid connection with the bike, ensuring effective power transfer and a secure fit. However, to maintain the best performance over time, proper maintenance is crucial. This guide will walk you through the necessary steps to keep your Shimano SM-SH12 [paid link] pedals in peak condition.

Why Maintenance Matters for Shimano SM-SH12 Pedals

Maintaining your Shimano SM-SH12 [paid link] pedals is essential for optimizing your cycling experience. Over time, wear and tear can lead to issues like squeaky pedals, loose engagement, and reduced power transfer. Regular maintenance helps prevent these problems, extending the lifespan of the pedals and ensuring consistent performance on every ride.

Step-by-Step Maintenance of Shimano SM-SH12 Pedals

1. Regular Cleaning

Dirt and debris can accumulate on the pedals, leading to friction and wear. Cleaning your pedals regularly will help prevent these issues.

  • How to Clean:
    • Remove the pedals from the bike using a pedal wrench [paid link] or an Allen key, depending on your pedal model.
    • Clean the pedal body using a soft brush or rag to remove dirt and grit. For hard-to-reach areas, use a toothbrush or a small detailing brush.
    • Rinse with water and allow to dry completely before reinstalling.

2. Inspect the Bearings

Shimano SM-SH12 pedals rely on smooth-bearing systems for efficient performance. If the bearings are worn out or damaged, it can cause friction, stiffness, or uneven rotation.

  • How to Inspect:
    • After removing the pedals, spin them manually to feel for any roughness or resistance in the bearing.
    • If the pedal does not rotate smoothly or feels gritty, the bearings may need to be serviced or replaced.

3. Lubrication

Proper lubrication ensures the pedal’s moving parts function smoothly, preventing corrosion and minimizing friction that can lead to excessive wear.

  • How to Lubricate:
    • Use a high-quality grease designed for bike components.
    • Apply a small amount of grease to the pedal threads before reattaching the pedals to the bike. This helps prevent seizing and creaking when riding.

4. Adjusting Tension

The Shimano SM-SH12 pedals are designed with adjustable tension settings, allowing riders to customize the release mechanism to their preferences. Over time, the tension may loosen or tighten due to regular use, affecting the ease with which you clip in and out.

  • How to Adjust Tension:
    • Find the tension screw on the side of each pedal.
    • Turn the screw clockwise to increase the tension (making it harder to clip in and out) or counterclockwise to reduce tension.
    • Test the tension after adjustments and make further tweaks as necessary to achieve the desired release strength.

5. Check for Cracks or Damage

Frequent use of the pedals, especially in harsh conditions, can lead to cracks or signs of damage. It’s important to check the pedals regularly to prevent potential failures while riding.

  • How to Inspect for Damage:
    • Examine the body of the pedal for visible cracks or deformities. Pay close attention to areas where the pedal contacts the crank arm.
    • Check for any play in the pedal’s movement, which can indicate internal damage.
    • If any cracks or significant wear are visible, replace the pedal to ensure safety and proper performance.

6. Replacing the Cleats

While not directly part of the pedal itself, the cleats are critical to the performance of the Shimano SM-SH12 pedal system. Over time, cleats can wear out, causing issues with clipping in and out of the pedals.

  • How to Replace the Cleats:
    • Inspect the cleats for wear and damage, such as worn-out edges or cracks.
    • If the cleats are worn or damaged, replace them promptly to maintain optimal pedal engagement and release.

Troubleshooting Common Pedal Issues

Even with proper maintenance, issues may arise with the Shimano SM-SH12 pedals. Here are some common problems and how to fix them:

  • Squeaky Pedals:
    • Cause: Dirt or lack of lubrication.
    • Fix: Clean the pedals thoroughly and apply fresh lubricant to the moving parts and pedal threads.
  • Pedals Feel Loose:
    • Cause: Loose pedal threads or worn bearings.
    • Fix: Tighten the pedal to the crank arm securely, ensuring it is properly installed. If the pedal still feels loose after tightening, inspect and replace the bearings if necessary.
  • Stiff Pedal Movement:
    • Cause: Dried-out grease or damaged bearings.
    • Fix: Clean and regrease the pedal’s moving parts. If the stiffness persists, the bearings may need to be replaced.

Tips for Prolonging the Life of Your Shimano SM-SH12 Pedals

  • Store in a Dry Area: After rides, store your bike in a dry place to prevent moisture from accumulating on the pedals and causing rust or corrosion.
  • Avoid Excessive Force: When installing or adjusting the pedals, avoid using excessive force to prevent damaging the pedal threads or the crank arm.
  • Check Regularly: Perform a quick inspection of the pedals every few weeks to ensure they are still in good condition. Catching small issues early can prevent bigger problems down the line.

Conclusion

Proper maintenance of your Shimano SM-SH12 pedals is essential for keeping them performing at their best. By regularly cleaning the pedals, inspecting the bearings, adjusting the tension, and replacing worn-out cleats, you can extend the lifespan of your pedals and enjoy a smoother, more efficient ride. Troubleshooting common issues quickly and addressing them promptly will also help you avoid any major problems. With a little care, your Shimano SM-SH12 pedals can continue to deliver top-tier performance for years to come.
