Öhlins is known for producing high-performance suspension systems, and the TTX1Air rear shock is a testament to their dedication to providing cutting-edge technology for road cyclists. In this comprehensive guide, we will delve into the installation, maintenance, troubleshooting, and optimization of the TTX1Air rear shock. Whether you are a beginner looking to understand the basics or an experienced rider aiming to fine-tune your setup, this guide will help you maximize the performance of your TTX1Air.
Installation of the TTX1Air Rear Shock
The TTX1Air rear shock is designed to offer both simplicity and high-end performance. Proper installation is critical to achieving the best ride quality and ensuring longevity. Here are the key steps to follow:
Step 1: Prepare the Bike
Ensure the bike is clean and stable before starting the installation process. It is essential to secure the bike on a stand to allow easy access to the rear suspension area.
Step 2: Remove the Old Shock (If Applicable)
If you are replacing an existing shock, use the appropriate tools to carefully remove it. Most rear shocks are attached with bolts at both the top and bottom of the shock body. Be sure to retain any washers or spacers for reinstallation if necessary.
Step 3: Install the TTX1Air Shock
Align the shock with the mount points on the bike frame, ensuring it is properly oriented. Insert the bolts and tighten them to the recommended torque specification. Be cautious not to overtighten, as this can damage the frame or shock components.
Step 4: Connect the Air Hose
The TTX1Air uses an air chamber to adjust the shock’s pressure. Attach the air hose to the shock’s valve, ensuring it is securely fastened. Use a shock pump to add air pressure according to the rider’s weight and preference.
Step 5: Test the Installation
Once the shock is installed, gently compress the rear suspension to ensure the shock moves freely. Check for any abnormal sounds or movement, indicating that the shock may not be properly seated.
Adjusting the TTX1Air Rear Shock
Adjusting the TTX1Air rear shock is vital for optimizing comfort and performance. The TTX1Air features multiple adjusters that allow you to fine-tune the shock to suit different riding conditions.
Air Pressure Adjustment
The air pressure determines the overall firmness of the shock. It is essential to set the right pressure to match your weight and riding style. Start by consulting the manufacturer’s recommendations for your weight category. Use a shock pump to add or release air until the desired pressure is achieved. Make sure to check the pressure regularly, as it can fluctuate over time.
Rebound Adjustment
The rebound adjuster controls how quickly the shock returns to its original position after compression. A slower rebound will result in more controlled movements, whereas a faster rebound can make the shock feel more responsive. To adjust, rotate the rebound knob, starting from a slow setting and gradually increasing speed to find the most comfortable setting for your riding style.
Compression Adjustment
The TTX1Air also includes a compression adjuster, which controls how the shock compresses under impact. This setting is crucial for controlling bottoming out and ensuring the shock remains responsive. For a smoother ride on rough terrain, set the compression to a softer setting. For faster, smoother trails, a firmer setting may be necessary.
Spring Rate Adjustment (if applicable)
The TTX1Air’s air spring system allows you to adjust the spring rate based on the terrain and your riding style. Depending on the bike’s geometry and usage, adjusting the air spring rate can help fine-tune the shock’s overall feel.
Maintenance of the TTX1Air Rear Shock
Routine maintenance is essential to keep the TTX1Air rear shock functioning optimally. Follow these steps to ensure long-term performance:
Cleaning the Shock
Regularly clean the shock using a damp cloth to remove dirt, debris, and moisture. Avoid using harsh chemicals or abrasive cleaners, as these may damage the shock’s seals and finishes. A clean shock ensures smoother performance and reduces wear over time.
Lubricating the Shock Seals
The seals on the shock should be lubricated to maintain smooth movement and prevent wear. Use a light oil or grease recommended by the manufacturer. Apply lubricant to the shock’s stanchion tubes and other moving parts where friction occurs. Avoid over-lubricating, as this can attract dirt.
Checking for Leaks
Air suspension systems can develop leaks over time. Regularly inspect the air valve and shock body for any signs of air loss. If the shock loses pressure quickly, it may indicate a leak in the seals or valve, which requires attention from a professional.
Servicing the Shock
Öhlins recommends having the TTX1Air rear shock serviced annually or after a heavy season of riding. Professional servicing involves disassembling the shock, inspecting internal components, replacing seals, and recharging the air spring. This ensures your shock performs at its peak for years.
Troubleshooting Common Issues with the TTX1Air Rear Shock
While the TTX1Air rear shock is built to last, issues can arise. Here are some common problems and troubleshooting tips:
Issue 1: Shock Bottoming Out
If the shock bottoms out during use, it may be due to insufficient air pressure or an improperly set compression damping. Ensure that the shock is set to the correct pressure for your weight and adjust the compression settings to prevent bottoming out on larger hits.
Issue 2: Inconsistent Rebound Performance
If the rebound feels too slow or too fast, adjust the rebound knob until you find a comfortable setting. If the issue persists, inspect the shock for any internal damage or leaks, as these could affect the rebound’s performance.
Issue 3: Loss of Air Pressure
If the shock loses air pressure quickly, check the air valve and hose for leaks. Replace any damaged seals or valves if necessary. A rapid loss of pressure may indicate a larger issue that requires professional servicing.
Customization and Optimization for Better Performance
The TTX1Air rear shock offers several customization options to tailor the ride to your preferences and optimize performance. Beyond basic air pressure adjustments, consider the following options:
Fine-Tuning Compression and Rebound
For advanced riders, fine-tuning both the compression and rebound settings can significantly affect ride quality. Experiment with different settings depending on the trail conditions and your riding style. Softer compression settings are ideal for rough, technical terrain, while firmer settings are better for smooth trails or high-speed riding.
Adjusting for Rider Weight and Riding Style
One of the best features of the TTX1Air shock is its adaptability to different rider weights and styles. Use a shock pump to set the correct air pressure based on your weight and adjust the compression and rebound for the optimal balance between comfort and control.
Comparison with Other Rear Shocks
When compared to other rear shock models, the TTX1Air offers a unique combination of performance and adjustability. Unlike many standard coil shocks, the air-sprung system in the TTX1Air provides a lighter and more customizable option. Additionally, Öhlins’ TTX technology gives the shock a distinct advantage in terms of compression control and ride smoothness, especially for riders who prioritize high-performance handling on a variety of terrains.
The TTX1Air’s compact design, combined with its advanced air spring system, makes it ideal for riders looking for a blend of lightweight construction and superior shock absorption. While other models may offer similar adjustability, few offer the same level of precision and durability as the TTX1Air.
Compatibility with Other Drivetrain Components
The TTX1Air rear shock is designed to work seamlessly with a wide range of road bike drivetrains. When pairing with other components, it is essential to ensure the shock’s travel and pressure range are compatible with the frame geometry and the intended use of the bike. Compatibility with rear suspension linkages and dropouts is also critical to ensure proper performance.
In most cases, the TTX1Air will work with any modern road bike drivetrain, but always check for clearance and mount compatibility before installation. The shock’s lightweight air spring system is adaptable, but it is best suited for high-performance road bikes that demand responsive and adjustable suspension systems.
