35 Pro 4 Wheels
Lightweight and Durable
The Fortus 35 Pro 4 wheels are built with the latest technology to ensure they are both strong and light. Constructed with a 6069 aluminum alloy, the rims are exceptionally stiff while maintaining a low weight. This results in a wheelset that can withstand high forces without compromising ride quality or increasing weight unnecessarily.
Wide Rim Profile
One of the standout features of the Fortus 35 Pro 4 wheels is their wide rim profile, measuring 35mm internal. This wider rim provides superior tire support, which allows for better tire performance, particularly in rough terrain. The extra width helps improve tire volume, providing better traction and comfort when riding over uneven surfaces.
Optimized for Tubeless Use
The Fortus 35 Pro 4 wheels come tubeless-ready, allowing for an easier setup and improved ride quality. Running tubeless tires reduces the risk of pinch flats, increases traction, and allows for lower tire pressures. This is particularly useful for off-road cycling, where the terrain can often cause traditional inner tubes to fail.
Pro 4 Hub Technology
Hope’s Pro 4 hubs are among the most reliable and efficient on the market. They feature an aluminum body that is both strong and lightweight, while the sealed bearings ensure smooth operation even in harsh conditions. The Pro 4 hub also boasts a high engagement mechanism with 44 points of engagement, ensuring quick and responsive power transfer to the wheels.
Customization Options
The Fortus 35 Pro 4 wheels offer excellent customization possibilities. Whether you’re looking for a specific axle configuration, color choice, or an upgrade to a different spoke count, Hope allows for a range of options to match your riding style and preferences.
Installation of Fortus 35 Pro 4 Wheels
Tools Required:
- 15mm or 12mm thru-axle (depending on your bike)
- Torque wrench [paid link]
- Spoke key (for wheel truing, if necessary)
- Tire levers
- Tubeless sealant
- Valve stems for tubeless setup
- 3mm hex wrench (for rotor attachment)
- Rotor locking tool
Step-by-Step Installation Process
- Remove the Old Wheels: Use the appropriate tool to remove your current wheels. If you are working with thru-axles, be sure to note the size for proper installation of the new wheels.
- Install the Front Wheel: Insert the Fortus 35 Pro 4 front wheel into the fork dropouts, aligning it with the axle holes. Tighten the thru-axle or quick release mechanism to the recommended torque setting.
- Install the Rear Wheel: Position the rear wheel into the bike’s rear triangle, ensuring that it is properly aligned with the chainstay. Tighten the axle to the correct torque specification.
- Install the Rotors: Attach the brake rotors to the Fortus 35 Pro 4 wheels using the 3mm hex wrench. Ensure they are tightly secured, but avoid over-tightening.
- Set Up Tubeless Tires: Insert the tubeless valve stems into the wheel, then mount the tire onto the rim. Add the appropriate amount of tubeless sealant and inflate the tire, making sure it seats properly on the rim.
- Check for Proper Wheel Alignment: Ensure both the front and rear wheels are straight and properly aligned. Perform a quick spin to check for any wobble or misalignment.
- Final Torque Check: Re-check all bolts, axles, and the rotor attachment for the recommended torque specification to ensure that everything is securely fastened.
Maintenance of Fortus 35 Pro 4 Wheels
Regular Cleaning
Keep your wheels clean by washing them regularly, especially after riding in muddy or wet conditions. Use mild soap and water, along with a soft brush to remove dirt and debris. Avoid using strong solvents that could damage the finish or seals.
Hub Maintenance
The Pro 4 hubs are known for their reliability, but it’s essential to service them regularly. Inspect the hubs every 6-12 months to ensure that the bearings are still running smoothly. If you hear any grinding noises or feel resistance while rotating the wheel, the bearings may need to be replaced or serviced.
Tubeless Setup Check
If you’re using tubeless tires, check the sealant level regularly. If it runs low, add more sealant to ensure that the tire continues to hold air effectively and maintain optimal performance. Inspect the rim tape and valve stems for any damage or wear.
Spoke Tension and Truing
Occasionally, check the spoke tension and true the wheel if necessary. The Fortus 35 Pro 4 wheels are designed to be stiff, but maintaining proper spoke tension is crucial for overall wheel longevity and performance. Use a spoke key to adjust the tension if needed.
Troubleshooting Common Set-Up Issues
Issue 1: Wheel Wobble
If you notice a wobble in the wheel after installation, it may be caused by improper spoke tension or misalignment during installation. Check the spoke tension using a spoke key and adjust accordingly. If the issue persists, the wheel may need to be trued by a professional.
Issue 2: Tubeless Tire Pressure Loss
If your tubeless tires are losing air, ensure that the valve stem is properly seated and that the rim tape is intact. Check for punctures in the tire or rim and inspect the sealant to ensure it is not too old or dried out.
Issue 3: Brake Rub
Brake rub can occur if the rotor is not properly aligned or the brake pads are rubbing against the rotor. Make sure that the rotors are installed correctly and check the calipers for proper alignment. A slight adjustment to the brake caliper position may be necessary.
Customization and Optimization for Better Performance
Hub Upgrades
While the Pro 4 hubs are already among the best in the industry, you can further optimize them by upgrading to a different engagement drive mechanism or experimenting with different freehub body materials for specific performance needs, such as weight savings or improved durability.
Tire Selection
Choose tires with a wider profile to take full advantage of the 35mm internal rim width. Wider tires will provide better comfort and traction, especially on rough terrain or during long rides. Consider tubeless-specific tires for smoother operation and fewer punctures.
Spoke Count Adjustments
For a more robust wheelset, you can consider increasing the spoke count, particularly for heavier riders or those who subject their wheels to extreme conditions. More spokes can provide additional strength and stability.
Comparison with Other Wheels
When comparing the Fortus 35 Pro 4 to other high-performance wheels, the Fortus wheels stand out due to their balance of weight, durability, and customization options. While some wheels may offer lighter setups, they often compromise on strength or rigidity. The Fortus 35 Pro 4 wheels, on the other hand, provide a sturdy, long-lasting option that performs exceptionally well in both competitive and recreational riding environments.
The Pro 4 hubs, with their quick engagement system, set the Fortus 35 Pro 4 apart from many competing wheels, making them the ideal choice for riders who require instant power transfer. Additionally, the wide rim profile provides superior tire performance, especially when paired with tubeless tires.
Understanding Compatibility with Other Drivetrain Components
The Fortus 35 Pro 4 wheels are designed to be highly compatible with a wide range of drivetrain components. Whether you’re using a Shimano or SRAM drivetrain, the rear hubs are compatible with multiple freehub bodies, allowing you to choose the system that best suits your needs.
When selecting your drivetrain components, ensure that the rear hub is matched to your cassette compatibility (Shimano or SRAM). The Fortus 35 Pro 4 wheels will work seamlessly with most modern drivetrains, provided the proper cassette and freehub body are installed.
