Tools Required
Before starting the installation or adjustment process, gather the following tools:
- 5mm and 6mm hex wrenches
- Torque wrench [paid link]
- Flathead screwdriver
- Allen key set
- Bike stand [paid link] (optional but helpful)
- Suspension oil (recommended by Formula)
- Rags for cleaning
- Brake rotor tool (if applicable)
- Fork seals and grease
Installation of the Formula Selva S
Step 1: Preparing Your Bike
Start by securely placing your bike on a stand. Make sure it is stable, and remove any parts that may obstruct the installation of the fork, such as the front wheel or brake caliper.
Step 2: Remove the Existing Fork
If you’re replacing an old fork, use a 5mm hex wrench to remove the stem bolts and carefully slide out the existing fork from the head tube. Keep an eye on the headset bearings and spacers, as they may need to be reused with the new fork.
Step 3: Install the Selva S Fork
Place the Formula Selva S fork into the head tube, aligning it properly with the headset. Ensure that the steerer tube is long enough for your bike’s head tube. You may need to cut the steerer tube if it is too long, using a pipe cutter or specialized fork cutting tool.
Step 4: Install the Stem and Tighten Bolts
Once the fork is in place, reattach your stem to the fork’s steerer tube. Ensure that the stem is aligned properly with the front wheel. Tighten the stem bolts with a torque wrench [paid link], applying the manufacturer’s recommended torque setting.
Step 5: Install the Brake and Front Wheel
If applicable, mount the front brake caliper to the fork’s brake mount. Follow the manufacturer’s guidelines for torque settings to prevent damage. After the brake is securely attached, install the front wheel, ensuring that the quick release or thru-axle is tightened appropriately.
Step 6: Check Alignment and Perform Final Adjustments
Ensure that the front wheel is aligned with the fork and the bike frame. Tighten any remaining bolts and check that the fork moves smoothly through its travel without obstruction.
Adjustment of the Formula Selva S
The Selva S is equipped with various adjustment features to customize your ride. Adjusting your fork settings based on your weight, riding style, and terrain can significantly enhance the performance of your bike.
Rebound Adjustment
The Selva S features an easy-to-use rebound adjuster, typically located at the bottom of the fork legs. To adjust the rebound, turn the knob clockwise for slower rebound and counterclockwise for faster rebound. A slower rebound will provide more control on technical terrain, while a faster rebound is better suited for smoother surfaces.
Compression Adjustment
The fork also includes compression adjustment, which can be tuned for either open or firm settings depending on the terrain. For more active and rough terrain, an open setting will provide better comfort and control. For smoother roads, firm settings will offer improved efficiency and reduce unnecessary fork movement.
Air Pressure Adjustment
Adjusting the air pressure within the Selva S is essential for achieving the right balance of support and comfort. Use a shock pump to fine-tune the air pressure based on your weight and desired ride feel. Formula recommends consulting the user manual for specific pressure guidelines. Proper pressure ensures that the fork performs at its peak [paid link], offering responsive suspension without bottoming out.
Maintenance of the Formula Selva S
Routine maintenance of your Selva S fork ensures its longevity and optimal performance. Follow these steps for regular upkeep:
Clean the Fork Regularly
After every ride, clean the fork using a damp cloth to remove dirt and debris. For more thorough cleaning, use a mild detergent and a brush to scrub the fork’s stanchions. Avoid using abrasive materials, as they can damage the fork’s surface.
Check for Leaks
Inspect the fork’s seals for any signs of oil leakage. If you notice oil around the seals, it may indicate that the seals need to be replaced. Replacing the seals regularly prevents dirt from entering the internals and prolongs the life of the fork.
Change the Oil
Formula recommends changing the suspension oil every 50 to 100 hours of riding. This process involves draining the old oil, cleaning the internals, and refilling with fresh suspension fluid. Make sure to use the oil type recommended by the manufacturer to maintain the fork’s performance.
Inspect the Stanchions and Seals
Check the stanchions for any scratches or damage. If there are any visible issues, you may need to replace the fork or the damaged components. Additionally, check the seals for wear. Worn seals can lead to performance issues and the entry of dirt, which can damage the internal parts.
Tighten Bolts
Regularly check the bolts on the fork to ensure they remain tight. Loose bolts can compromise the fork’s performance and safety.
Troubleshooting Common Issues
Fork Not Moving Smoothly
If the fork is not moving smoothly, it could be due to incorrect air pressure, low oil levels, or dirt in the seals. Start by checking the air pressure and ensuring that it matches your weight and riding style. If the fork still doesn’t move smoothly, inspect the oil levels and replace the oil if needed.
No Rebound or Slow Rebound
If the rebound adjustment is ineffective, it could indicate that the rebound damper is clogged or malfunctioning. In such cases, disassemble the fork and clean the damper before reassembling it. If the problem persists, it may be time to replace the rebound damper.
Leaking Oil
Oil leaks from the fork are usually caused by damaged or worn seals. Replace the seals and ensure that the oil levels are appropriate. If oil continues to leak, further inspection may be required to identify any internal issues.
Customization and Optimization
The Selva S offers a variety of adjustments to suit different riders’ preferences. To optimize its performance, consider fine-tuning the following:
- Air Pressure: Adjust the air pressure based on your weight and riding style for optimal suspension.
- Compression Settings: Experiment with the compression settings to find the ideal balance between comfort and performance.
- Rebound: Adjust the rebound to suit your terrain and riding style, ensuring that the fork doesn’t rebound too quickly or slowly.
Comparison with Similar Models
When compared to other forks in the same class, such as the RockShox SID or the Fox 32, the Selva S stands out due to its combination of lightweight design, adjustable features, and superior damping performance. Riders who prefer a more customizable and responsive suspension system may find the Selva S a superior option, especially for road cycling. While the RockShox SID offers a slightly lower weight and is known for its stiff chassis, the Selva S provides greater adjustability, making it a versatile [paid link] choice for riders who need adaptability on various terrains.
Compatibility with Other Drivetrain Components
The Formula Selva S is designed to work seamlessly with modern road bike drivetrains. It pairs well with a wide range of handlebars, stems, and headsets, making it an excellent upgrade for most road bikes. However, it’s important to ensure that the steerer tube length is compatible with your bike’s head tube, as not all headsets have the same dimensions. Additionally, when upgrading to a suspension fork like the Selva S, you may need to adjust your brake setup to accommodate the additional fork travel.
