Installation of the Recon RL SL Suspension Fork

Step 1: Removing the Old Fork

Before installing your new Recon RL SL, you’ll need to remove your current fork.

  • Start by loosening and removing the front wheel, brake caliper, and any other components connected to the fork.
  • Loosen the stem bolts, and slide the fork out of the headset.
  • Remove any headset spacers and ensure the headset is in good condition before installing the new fork.

Step 2: Installing the New Fork

  • Slide the Recon RL SL into the headset, ensuring it is properly aligned and the crown race is properly seated on the fork’s steerer tube.
  • Reattach the headset spacers and stem. Tighten the stem bolts evenly to secure the fork in place.
  • Reinstall the front wheel and connect the brake caliper, ensuring everything is correctly aligned and tightened.

Step 3: Checking Alignment

  • Ensure the fork is straight and aligned with the front wheel and frame.
  • Double-check that all components are tightened to the manufacturer’s torque specifications.

Adjusting the Recon RL SL Suspension Fork

The Recon RL SL is equipped with several adjustment features to help riders dial in their suspension. These include compression, rebound, and air pressure adjustments. Here’s how to make the most out of these settings:

Air Pressure

The air pressure in your fork determines its overall stiffness and responsiveness. Setting the right air pressure is crucial for optimal performance.

  • Find your ideal air pressure by consulting the RockShox recommended air pressure chart for your weight and riding style.
  • Use a high-quality shock pump to adjust the pressure through the air valve located on the top of the fork leg.
  • Start by setting the air pressure to the recommended value, then adjust based on your preferences. If you feel that the fork is too stiff or too soft, make small adjustments in 5-10 psi increments.

Compression Damping

Compression damping controls the speed at which the fork compresses during impacts. Adjusting this setting affects how the fork handles small bumps and big hits.

  • The Recon RL SL has an external compression adjustment knob on the left leg. Turning it clockwise increases compression damping, making the fork stiffer. Turning it counterclockwise decreases the damping, making the fork more plush.
  • Set the compression damping based on your riding terrain. For smoother trails, reduce compression to maintain comfort. For rougher, technical trails, increase compression to prevent bottoming out.

Rebound Damping

Rebound damping controls the speed at which the fork returns to its full extension after compressing.

  • The rebound adjuster is located on the right fork leg. Turning it clockwise slows down the rebound, while turning it counterclockwise increases the rebound speed.
  • Adjust the rebound setting based on your riding style and the terrain you’ll be tackling. For smoother terrain, faster rebound is generally preferred. For technical, rough terrain, slower rebound will improve stability.

Maintenance of the Recon RL SL Fork

Regular Cleaning

Proper cleaning is essential for the longevity and performance of your Recon RL SL fork.

  • Clean the fork stanchions regularly to remove dirt, mud, and debris. This will reduce wear and tear on the seals.
  • Use a soft cloth and mild soap with warm water. Avoid using harsh chemicals or abrasives that could damage the fork’s finish.
  • After cleaning, inspect the seals and wipe them down to prevent dirt from accumulating and causing leaks.

Lubricating the Fork

Keeping the fork’s internals lubricated helps maintain smooth performance and prevents unnecessary friction.

  • Every 50 hours of riding, or once a month, check and lubricate the fork’s air spring. This helps maintain proper air seal performance.
  • Replacing the oil and lubricating the damper and air spring every 100-150 hours is recommended to ensure optimal functioning.

Servicing the Fork

Over time, the fork will need more thorough servicing.

  • Every 200-300 hours of use, it’s important to perform a full service, including changing the oil, inspecting seals, and checking for any wear on critical components.
  • If you notice unusual noises or feel a decrease in performance, it may be time to service the fork sooner.

Troubleshooting Common Set-up Issues

Fork Bottoming Out

If the fork bottoms out during big hits or rough terrain, it could be a sign that the air pressure is too low or the compression damping is too soft.

  • Increase the air pressure slightly or tighten the compression knob to increase firmness and prevent bottoming out.
  • If the issue persists, check the fork for damage, especially the air spring and seals.

Poor Rebound Performance

If the fork feels sluggish or too bouncy, the rebound damping might not be set correctly.

  • Adjust the rebound to a slower setting if the fork is too bouncy.
  • If it’s sluggish, try speeding up the rebound by turning the adjuster counterclockwise.

Leaking Air or Oil

If you notice any leaking around the seals or air valve, this may indicate that the seals are worn or damaged.

  • Replace the seals to prevent air or oil loss. Regular seal maintenance and replacement are essential to keep the fork working efficiently.

Customization and Optimization

The Recon RL SL can be tailored to fit your riding style and preferences. By adjusting air pressure, compression, and rebound settings, you can fine-tune the fork for comfort, control, and performance.

  • Trail Riders: Set a medium air pressure with moderate compression damping for a balanced ride. Increase rebound damping slightly for better stability on descents.
  • XC Riders: For cross-country riders, lower the air pressure to achieve a smoother, more plush feel, and set the compression damping to the minimum to absorb smaller bumps without losing efficiency.

Customizing these settings allows you to maintain optimal performance, whether you’re tackling fast descents or navigating technical climbs.

Comparison with Similar Models

When comparing the RockShox Recon RL SL to other suspension forks in its category, such as the RockShox Reba or the Fox 32, there are several key differences:

  • Weight: The Recon RL SL is typically lighter than the Fox 32, making it a good option for riders who prioritize weight savings.
  • Adjustability: The Recon RL SL offers a solid range of adjustability, including external compression and rebound knobs, which is similar to the Reba. However, some models may offer more advanced features like remote lockouts.
  • Price Point: The Recon RL SL is a more affordable option compared to high-end models like the Fox 32, making it an excellent choice for riders on a budget.

Overall, the Recon RL SL is an excellent choice for riders who need solid performance without breaking the bank. It offers a good balance of adjustability, durability, and weight savings for most riding styles.

Compatibility with Other Drivetrain Components

The Recon RL SL is designed to work seamlessly with a variety of drivetrain components, from entry-level to mid-range setups. However, it is essential to ensure proper compatibility with your bike’s frame and headset before installation. It is best suited for bikes with a 100mm to 120mm travel range, typically found on cross-country and light trail bikes. For compatibility, double-check the following:

  • Steerer Tube Diameter: Ensure your bike’s headset is compatible with the fork’s steerer tube diameter (typically 1 1/8″ or tapered).
  • Axle Type: The Recon RL SL comes with a standard quick release or a through-axle. Make sure your frame supports the type of axle used by the fork.
  • Brake Mounting: The Recon RL SL is compatible with post-mount disc brakes, so ensure your frame is designed to accommodate post-mount brake calipers.

By ensuring compatibility between your Recon RL SL and other drivetrain components, you’ll enjoy smooth performance and easy integration with your bike.
