he TriAir2 Rear Shock
The TriAir2 is designed for both cross-country and trail riders who want a rear shock that offers the perfect balance between performance and durability. Here’s a breakdown of the core features:
1. Air Spring System
The TriAir2 utilizes a high-quality air spring system that ensures optimal performance across different riding conditions. This air spring is adjustable, allowing you to fine-tune the shock’s compression and rebound to match your specific riding style and terrain. The system provides a lighter weight compared to coil-spring shocks, which translates to better efficiency and speed on the trail.
2. Advanced Damping Technology
SR Suntour has incorporated their proprietary “RC2” damping system into the TriAir2, providing enhanced control and stability. The dual-compound damping offers separate adjustment for compression and rebound, allowing you to precisely adjust the shock for maximum comfort and performance. This system is particularly useful on rough, technical trails where precise shock control can make all the difference.
3. Long-Lasting Durability
Made with a rugged [paid link] alloy body, the TriAir2 is designed to endure the stresses of aggressive riding. The shock features a hard-anodized finish that resists wear and corrosion, making it a reliable choice for riders who demand durability and performance.
4. Adjustability
The TriAir2 excels in terms of adjustability. Riders can fine-tune the shock’s air pressure, compression, and rebound settings, offering personalized control over how the shock responds to different trail features. Whether you prefer a softer, more plush ride or a stiffer, more efficient shock for climbing, the TriAir2 can accommodate your preferences.
5. Compatibility
This rear shock is compatible with a wide range of bike frames and drivetrains. Whether you ride a full-suspension mountain bike or a specific SR Suntour frame, the TriAir2 can be seamlessly integrated into your setup.
Installation of the SR Suntour TriAir2 Rear Shock
Tools Required:
- Shock pump
- 5mm Allen wrench [paid link]
- Torque wrench [paid link]
- Suspension grease
- Protective gloves
Installation Steps:
- Prepare the Frame
Ensure the bike frame is clean and free of debris, particularly around the rear shock mount area. Apply a light coat of suspension grease to the mounting hardware to prevent creaks and ensure smooth operation. - Remove the Old Shock (if applicable)
If replacing an existing shock, carefully remove the bolts securing it to the frame using a 5mm Allen wrench [paid link]. Take note of any spacers or washers, as they may be needed for the installation of the new shock. - Install the TriAir2 Shock
Align the TriAir2 rear shock with the mounting points on the frame. Ensure that the shock’s eyelets match the frame’s mounts. Insert the bolts and tighten them using a torque wrench [paid link], following the manufacturer’s recommended torque specifications (typically around 8-10 Nm). - Set the Air Pressure
Using a shock pump, adjust the air pressure in the TriAir2 to match your body weight and riding style. The ideal air pressure range can be found in the owner’s manual, but typically, you’ll want to start with a pressure that allows for around 20-30% sag when seated on the bike. - Adjust Compression and Rebound Settings
Once the shock is installed and inflated, adjust the compression and rebound settings to your liking. The TriAir2 features two external dials for compression and rebound adjustments, allowing you to fine-tune the ride based on your preferences and terrain. - Test Ride and Fine-Tune
After installation, take the bike for a test ride. Pay attention to the shock’s performance on different trail features and make any necessary adjustments to the compression or rebound settings. It may take a few rides to dial in the perfect setup for your needs.
Troubleshooting Common Set-Up Issues
1. Shock Bottoming Out
If you find that the TriAir2 rear shock is bottoming out too easily on rough terrain, it may be a sign that the air pressure is too low. Try increasing the pressure by small increments (5-10 psi) and retesting the shock until you find a suitable pressure that prevents bottoming out without compromising comfort.
2. Excessive Rebound
If the shock rebounds too quickly after compression, it can make the ride feel bouncy and unstable. In this case, you should slow down the rebound by turning the rebound dial clockwise. Be sure to make small adjustments and test the shock after each change.
3. Noise or Creaking
Creaking sounds can sometimes occur due to improperly tightened bolts or a lack of lubrication on the shock mount points. Recheck the torque settings and apply fresh suspension grease to the mounting hardware if necessary. Make sure to clean the frame and shock regularly to prevent dirt buildup that can contribute to creaks.
4. Air Pressure Loss
If you notice a gradual loss of air pressure in the shock, inspect the air valve and shock seals for any damage. A slow leak may be caused by worn seals or an improperly sealed air valve. If you can’t find the issue, consider having the shock serviced by a professional.
Maintenance Tips for the TriAir2 Rear Shock
1. Regular Cleaning
Keep the shock clean to prevent dirt and debris from interfering with its performance. After every ride, wipe down the shock with a clean, dry cloth. For more thorough cleaning, use mild soap and water. Avoid using high-pressure water jets, as they can damage the shock’s seals.
2. Seal Maintenance
Inspect the seals periodically for wear or damage. If you notice any leaking air or oil, it’s time to replace the seals. Replacing the seals regularly will help extend the life of your shock and maintain consistent performance.
3. Air Pressure Checks
It’s essential to check the air pressure before every ride, especially after significant temperature changes. Air pressure can fluctuate with temperature, so a quick check ensures that the shock performs at its best.
4. Full Suspension Service
Every 50-100 hours of riding, it’s advisable to have your rear shock serviced professionally. This includes draining and replacing the oil, inspecting the damper for wear, and checking the seals. Regular servicing ensures the longevity of your TriAir2 and optimal performance.
Customization and Optimization
The TriAir2 rear shock offers a range of customization options that can significantly improve your riding experience. Adjusting the shock’s air pressure, compression, and rebound settings is the key to tailoring its performance to your specific needs. For example, if you’re tackling steep downhill sections, reducing compression stiffness and slowing down the rebound can help manage the shock’s response. Conversely, for cross-country rides where efficiency is paramount, increasing compression and using a firmer rebound can maximize pedaling efficiency.
Comparison with Similar Models
When comparing the TriAir2 to similar rear shocks, such as the Fox Float X2 or RockShox Super Deluxe, the TriAir2 stands out for its combination of performance and affordability. While the Fox and RockShox models are often more expensive, the TriAir2 offers a similar range of adjustability and durability, making it an excellent choice for riders on a budget who still want high-end performance. The TriAir2 is particularly praised for its smooth air spring and high-quality damping system, which delivers excellent comfort on a wide range of terrain.
Compatibility with Other Drivetrain Components
The TriAir2 is compatible with most modern full-suspension mountain bike frames that use standard shock mount sizes. When choosing a rear shock, ensure that the frame’s shock mount spacing matches the specifications of the TriAir2. Additionally, the shock’s performance is optimized when paired with other high-quality drivetrain components, such as a Shimano or SRAM drivetrain. The adjustable nature of the TriAir2 allows it to integrate seamlessly with various suspension systems, enhancing overall bike handling and comfort.
