The RockShox Bluto RL is a highly regarded suspension fork designed for fat bikes, providing excellent performance on both soft and rugged terrains. Whether you’re tackling snow, sand, or rough mountain trails, understanding how to adjust and maintain the Bluto RL fork is essential for optimizing your riding experience. This guide will walk you through the steps to adjust, maintain, troubleshoot, and fine-tune your Bluto RL suspension fork for better performance.

Installation of the RockShox Bluto RL

Before performing any adjustments, it’s crucial to correctly install the Bluto RL fork. The process of installation is straightforward, but make sure to follow each step carefully to ensure your fork functions properly.

Steps for Installing the Bluto RL Fork:

  1. Remove the Old Fork: Begin by removing your current fork, if applicable. This typically involves removing the front wheel, brake caliper, and headset cap, then loosening the fork’s steerer tube clamp.
  2. Prepare the Bluto RL: Slide the Bluto RL fork’s steerer tube into the head tube of your bike. Ensure the fork is facing the correct direction, with the brake mount on the right side (if using a right-hand brake setup).
  3. Install the Headset and Stem: Once the fork is in place, reinstall the headset components (lower and upper headset bearings) and tighten the stem to the steerer tube.
  4. Install the Front Wheel: After the fork is securely mounted, install the front wheel, making sure the axle is properly aligned with the dropouts.
  5. Reattach the Brake Caliper: Finally, attach your brake caliper to the fork’s brake mounts, ensuring it is correctly positioned and secured.

Adjusting the RockShox Bluto RL Fork

Adjusting the suspension fork for different riding conditions is essential for getting the most out of the Bluto RL. It features a simple but effective range of adjustments, including rebound damping and air spring pressure.

1. Air Spring Pressure Adjustment

The Bluto RL uses an air spring system that can be adjusted to match the rider’s weight and riding style. Correct air pressure is vital to maintaining proper suspension performance.

  • Set the air pressure: Use a shock pump to adjust the pressure. Check the recommended air pressure based on your weight, typically found in the owner’s manual. If you’re unsure, start with a mid-range setting and adjust based on your preferences and riding conditions.
  • Test the sag: To check your fork’s sag, apply your full body weight on the bike and measure the amount the fork compresses. Aim for about 15-25% of the fork’s total travel as sag, depending on your riding style.

2. Rebound Damping Adjustment

Rebound damping controls the speed at which the fork returns to its original position after compressing. This is critical for maintaining control and comfort, especially on rough terrain.

  • Adjust the rebound: The Bluto RL features an external rebound adjuster at the bottom of the right leg. Turning the adjuster clockwise increases rebound damping, slowing the fork’s return. Turning it counterclockwise decreases rebound damping, allowing the fork to return more quickly.
  • Tune the rebound: Adjust the rebound to suit your riding conditions. If the fork is too slow to return, you may feel like you’re bouncing or losing control on successive bumps. If it returns too quickly, you may experience a harsh, jarring ride.

3. Compression Damping Adjustment

Compression damping controls the fork’s response to impacts and rider input. The Bluto RL has a simple yet effective compression adjuster located on the left leg.

  • Adjust the compression: Turning the compression dial clockwise increases compression damping, making the fork stiffer and less likely to compress on small bumps. Turning it counterclockwise softens the fork, allowing it to absorb smaller bumps more effectively.
  • Choose your preferred setting: Riders who prefer a firmer, more responsive fork might opt for a higher compression setting, while those who want a plush, absorbent ride will benefit from a softer setting.

Maintaining the RockShox Bluto RL Fork

Regular maintenance ensures that your Bluto RL fork remains in top condition for years to come. Key areas to focus on include cleaning, lubrication, and servicing the air spring.

1. Cleaning and Lubrication

Proper cleaning and lubrication are vital to keeping the fork functioning smoothly.

  • Clean the stanchions: After every ride, clean the fork’s stanchions with a soft cloth to remove any dirt or debris. This prevents contaminants from entering the fork’s internals.
  • Lubricate seals: Apply a light layer of fork oil to the seals around the stanchions to keep them lubricated. This helps prevent wear and tear on the seals, ensuring smooth operation.

2. Fork Oil and Air Spring Service

Periodically, the fork’s air spring and damping oil will need servicing.

  • Air spring service: Check the air spring pressure regularly, especially after long rides. Replacing the air spring’s seals and lubricating it is recommended every 50-100 hours of riding, depending on use.
  • Oil change: Changing the oil inside the fork’s damping system is essential for maintaining consistent performance. This can be done at home with basic tools or at a professional service center.

Troubleshooting Common Bluto RL Fork Issues

Even with regular maintenance, issues can arise with the Bluto RL fork. Here are some common problems and how to troubleshoot them.

1. Fork Feeling Too Stiff or Too Soft

  • Too stiff: If the fork feels overly stiff, reduce the air pressure slightly and check that the rebound is not set too fast.
  • Too soft: If the fork feels too soft and bottoming out frequently, increase the air pressure and check the compression settings to ensure they’re not set too soft.

2. Rebound or Compression Issues

  • Rebound too fast or too slow: Adjust the rebound dial accordingly. If the fork feels like it’s pogoing (bouncing), slow down the rebound. If it feels sluggish, increase the rebound speed.
  • Compression damping issues: If the fork is either too harsh or too soft, adjust the compression damping dial. For harsher conditions, increase the compression damping; for softer, smoother rides, reduce it.

Customizing the Bluto RL Fork for Better Performance

Customization is key for getting the most out of your Bluto RL suspension fork. Fine-tuning the air pressure, rebound, and compression settings can drastically improve your ride quality based on terrain and personal preference.

1. Fine-Tuning for Terrain Types

  • Snow and sand: For soft conditions like snow or sand, reduce the air pressure slightly to increase the fork’s ability to absorb small bumps and provide more traction.
  • Rocky trails: On rough, rocky trails, increase the air pressure to prevent bottoming out and use higher compression damping for more control.

2. Weight-Specific Adjustments

  • Heavy riders: If you’re on the heavier side, start with higher air pressure and more rebound damping to prevent excessive fork compression.
  • Light riders: Lighter riders can reduce air pressure for a more responsive feel, with lower compression damping for a plush, smooth ride.

Comparing the Bluto RL with Other Fat Bike Suspension Forks

When choosing a suspension fork for a fat bike, it’s essential to understand how the Bluto RL compares with similar models, like the Fox Float 34 or the Manitou Mastodon.

1. Bluto RL vs. Fox Float 34

  • Travel: The Bluto RL offers 100mm of travel, while the Fox Float 34 offers a similar range, but the Float 34 is known for its premium damping system, which may provide slightly better performance in high-speed situations.
  • Weight: The Bluto RL is typically lighter than the Fox Float 34, making it a better option for riders looking to reduce overall bike weight without sacrificing performance.

2. Bluto RL vs. Manitou Mastodon

  • Adjustability: The Manitou Mastodon offers more advanced adjustability options compared to the Bluto RL, such as hydraulic damping adjustments. However, the Bluto RL offers a more straightforward setup with less complexity, making it ideal for riders seeking simplicity and ease of use.
  • Performance: Both forks excel in rough terrain, but the Bluto RL’s more cost-effective design makes it an excellent choice for riders on a budget.

Compatibility with Other Drivetrain Components

The RockShox Bluto RL fork is compatible with a wide range of fat bike components. When choosing components for your bike, ensure the fork’s axle size, brake mounts, and headset dimensions match your other components. It’s essential to verify that your chosen wheelset is compatible with the fork’s thru-axle standards.
