How To Change Bike Pedals

Changing your bike pedals might seem daunting, but it's a relatively straightforward process that can be accomplished with basic tools. Whether you're upgrading to clipless pedals for enhanced performance or simply replacing worn-out pedals, this guide will walk you through the steps, ensuring a smooth and successful pedal swap.

Tools You'll Need

Before you begin, gather the following tools:

  • Pedal wrench: This specialized wrench has a 15mm (usually) open-end wrench on one side and a 9/16" wrench on the other. Essential for removing and installing pedals. Don't attempt this with adjustable wrenches; you risk damaging the pedals or crank arms.
  • Penetrating oil (optional): If your pedals are particularly stubborn due to corrosion or age, applying penetrating oil beforehand can significantly ease removal. Allow it to sit for 15-20 minutes to work its magic.
  • Gloves (optional): Protect your hands from grease and potential scratches.
  • Grease (recommended): A thin layer of grease on the threads of the new pedals will prevent seizing in the future.

Removing the Old Pedals

This is where the pedal wrench comes into play. Remember: Pedal threads are reverse threaded. This means the left pedal tightens clockwise and the right pedal tightens counter-clockwise. Many cyclists find this counterintuitive, but it's a standard design feature.

  1. Identify the Left and Right Pedals: The left pedal is on the left crank arm (as you sit on the bike), and the right pedal is on the right crank arm.
  2. Apply Penetrating Oil (if needed): If you're struggling with rusty or stuck pedals, spray penetrating oil around the pedal spindle where it meets the crank arm. Let it soak for 15-20 minutes.
  3. Secure the Pedal Wrench: Firmly position the pedal wrench onto the pedal. Ensure a good grip to avoid slippage.
  4. Unscrew the Pedals: For the right pedal, turn the wrench counter-clockwise. For the left pedal, turn the wrench clockwise. This might require considerable force; use your body weight to apply sufficient torque if necessary.
  5. Remove the Pedals: Once the pedals are loose, they should unscrew relatively easily. If you encounter significant resistance, reapply penetrating oil and allow it to sit again.

Installing the New Pedals

With the old pedals removed, it's time to install the new ones.

  1. Apply Grease: Apply a thin layer of grease to the threads of the new pedal spindles. This will help prevent corrosion and make future removal easier.
  2. Insert the Pedals: Carefully align the new pedals with the crank arms.
  3. Screw in the Pedals: Remember the reverse threading: The right pedal tightens counter-clockwise, and the left pedal tightens clockwise. Screw them in by hand initially to ensure proper alignment.
  4. Tighten with the Pedal Wrench: Use the pedal wrench to firmly tighten the pedals. This requires considerable force to ensure a secure fit and prevent the pedals from loosening during riding.

Important Considerations

  • Torque Specifications: Consult your bike's manual or the pedal manufacturer's instructions for the recommended torque specifications. Over-tightening can damage the crank arms.
  • Damaged Crank Arms: If you encounter excessive resistance when removing or installing pedals, it's possible the crank arms are damaged. If so, consider seeking professional bike repair services.
  • Different Pedal Types: The process remains largely the same for different types of pedals (flat, clipless, etc.), though the specific tools may vary depending on the pedal design.

By following these steps, you can successfully change your bike pedals and enjoy a smoother, more efficient ride. Remember safety first, and don't hesitate to seek professional help if you're unsure about any part of the process. Happy cycling!
