3. Safety Information

Read all safety information before installation and use. Failure to follow these instructions may result in injury or damage to your bicycle.

• Always wear appropriate safety gear, including a helmet and protective footwear, when cycling.
• Ensure pedals are securely tightened before each ride. Loose pedals can cause accidents.
• Regularly inspect pedals for any signs of wear, damage, or loose components. Replace damaged parts immediately.
• Keep hands and clothing clear of moving parts during installation and operation.

4. Setup and Installation

Follow these steps to properly install your new ROCKBROS Mountain Bike Pedals.

1. Identify Left and Right Pedals: Each pedal is marked with an 'L' for left and 'R' for right. The 'L' pedal installs on the left crank arm (non-drive side), and the 'R' pedal installs on the right crank arm (drive side).

Image 4.1: The left pedal (marked 'L') and right pedal (marked 'R') are distinct. Note the 'L' and 'R' markings on the pedal axles.
2. Prepare Crank Arms: Ensure the threads on your bicycle's crank arms are clean and free of debris. Applying a small amount of grease to the pedal threads is recommended to prevent seizing and facilitate future removal.
3. Install Left Pedal: Insert the 'L' pedal into the left crank arm. Remember that the left pedal has a left-hand thread, meaning you turn it counter-clockwise to tighten. Hand-tighten first to ensure proper thread engagement.
4. Install Right Pedal: Insert the 'R' pedal into the right crank arm. The right pedal has a right-hand thread, meaning you turn it clockwise to tighten. Hand-tighten first.
5. Final Tightening: Use a 15mm pedal wrench or an appropriate hex key (depending on your pedal's axle design) to firmly tighten both pedals. Do not overtighten, but ensure they are secure to prevent loosening during use.

5. Operating Instructions

These pedals are designed for intuitive use, providing a stable platform for your feet.

• Foot Placement: Position the ball of your foot over the pedal axle for optimal power transfer and control.
• Grip: The anti-slip pins will engage with your shoe soles, providing a secure connection. This design minimizes foot slippage, especially in wet or bumpy conditions.
• Adaptation: If transitioning from clipless pedals, allow some time to adjust to the feel of platform pedals and finding your preferred foot position.

6. Maintenance

Regular maintenance will extend the lifespan and ensure the optimal performance of your pedals.

• Cleaning: Clean the pedals regularly with a damp cloth to remove dirt and mud. Avoid using harsh chemicals that could damage the finish or bearings.
• Bearing Check: Periodically check the bearings for smoothness. If you notice any grinding, excessive play, or resistance, the bearings may require servicing or replacement. The sealed design helps protect them, but extreme conditions can still affect them.
• Pin Inspection: Inspect the anti-slip pins for wear or damage. If any pins are missing or severely worn, they may need to be replaced to maintain optimal grip.
• Tightness Check: Before each ride, quickly check that the pedals are still securely tightened to the crank arms.

7. Troubleshooting

Here are solutions to common issues you might encounter with your pedals.

• Pedals Feel Loose:
  Solution: Re-tighten the pedals to the crank arms using a pedal wrench or hex key. Ensure you are turning in the correct direction for each pedal (left-hand thread for left pedal, right-hand thread for right pedal).
• Squeaking or Clicking Noise:
  Solution: This often indicates loose pedals or dry threads. Remove the pedals, clean the threads on both the pedals and crank arms, apply fresh grease, and re-install them securely. If the noise persists, the pedal bearings may need inspection or replacement.
• Reduced Grip:
  Solution: Check the anti-slip pins. If they are worn down or missing, consider replacing them or the pedals entirely for optimal safety and performance. Ensure your footwear has appropriate soles for platform pedals.
• Difficulty Installing/Removing Pedals:
  Solution: Ensure you are turning in the correct direction (left pedal is reverse threaded). If pedals are seized, applying penetrating oil and allowing it to soak may help. Always use the correct tools.
