Installation of the TTX2Air Rear Shock

Installing the Öhlins TTX2Air rear shock is a straightforward process, but it requires precision and care. Follow these steps to ensure a proper and secure installation:

  1. Preparation:
    • Ensure your bike frame is compatible with the TTX2Air’s eye-to-eye length and stroke length.
    • Gather the necessary tools: torque wrench [paid link], Allen keys [paid link], suspension grease, and a shock pump.
  2. Remove the Old Shock:
    • Use an Allen key to remove the bolts securing the old rear shock. Keep the bolts safe as you will need them to install the TTX2Air.
    • If necessary, use a suspension grease to lubricate the contact points on the shock mounts.
  3. Install the TTX2Air Rear Shock:
    • Position the TTX2Air into the shock mount on the bike frame.
    • Align the shock mounts with the holes on the frame. Make sure the shock’s eyelets are facing the right direction.
    • Tighten the bolts using a torque wrench [paid link] to the manufacturer’s recommended torque setting, typically 10-15 Nm.
  4. Inflate the Shock:
    • Attach a shock pump to the air valve and adjust the air pressure according to your rider weight and preferences.
    • Ensure the air pressure is within the recommended range, typically between 180-230 PSI for optimal performance.
  5. Test the Installation:
    • After installation, compress the shock a few times to ensure smooth movement and proper alignment. Check for any unusual sounds or friction points.

Adjustment and Fine-Tuning of the TTX2Air Rear Shock

The TTX2Air is equipped with advanced adjustments that can be customized to suit various riding styles and terrains. Here’s how to fine-tune the shock for optimal performance:

  1. Rebound Adjustment:
    • The TTX2Air features a rebound adjuster, typically located on the shock’s shaft. Turn it clockwise to slow down the rebound and counterclockwise to speed it up.
    • Start with a medium rebound setting and test on the trails. Adjust as needed for a more controlled return after each compression.
  2. Compression Adjustment:
    • The TTX2Air offers separate high- and low-speed compression adjustments. High-speed compression affects the shock’s performance during fast, aggressive impacts, while low-speed compression is for smaller, slower movements.
    • Adjust the high-speed compression dial to control big hits and impacts. A stiffer setting is ideal for aggressive riders or rough terrain.
    • Use the low-speed compression to modify the shock’s response to body weight shifts, allowing for better pedaling efficiency.
  3. Air Spring Pressure:
    • The air spring pressure controls the overall feel of the shock. Higher pressure provides more support, while lower pressure gives a softer, more compliant feel.
    • Adjust the air spring pressure based on your body weight and riding style. Lighter riders may prefer lower pressures, while heavier riders may need higher air pressures for better support.
  4. Fine-Tuning:
    • The TTX2Air features a lockout function, which is ideal for climbing or smooth trails. Use the lockout to prevent unwanted movement in the shock when pedaling on flatter, less technical terrain.
    • Regularly check the shock settings and make adjustments as the conditions change or after significant rides.

Maintenance of the TTX2Air Rear Shock

Routine maintenance is essential to ensure the TTX2Air rear shock performs at its best for many years. Here’s how to keep it in top condition:

  1. Cleaning:
    • After every ride, wipe down the shock body with a clean cloth to remove dirt and debris. Pay particular attention to the shock seals to prevent dirt from entering the internals.
    • Use a mild soap solution and water to clean the shock, but avoid using solvents or degreasers that could damage the seals.
  2. Inspection:
    • Inspect the shock for any visible signs of damage, such as cracks, dents, or oil leaks. Pay close attention to the seals and ensure they are not worn or damaged.
    • Check the shock’s air pressure and adjust it according to the manufacturer’s recommendations, especially after long rides or rough terrain.
  3. Lubrication:
    • Apply a light coat of suspension grease to the shock mounts where the shock contacts the frame. This reduces friction and helps maintain smooth shock movement.
  4. Service:
    • The TTX2Air should be serviced by a professional technician every 100-150 hours of riding. During the service, the shock will be disassembled, cleaned, and recharged with oil if necessary. This ensures all internal components are functioning properly.

Troubleshooting Common Issues with the TTX2Air Rear Shock

Despite its robust design, the TTX2Air may encounter a few common issues. Here’s how to troubleshoot them:

  1. Shock Is Not Holding Air Pressure:
    • If the shock is losing air pressure, the most likely cause is a damaged air seal. Inspect the seals for any visible damage and replace them if necessary.
    • If air loss continues, take the shock to a certified technician for a full inspection.
  2. Excessive Rebound:
    • If the shock rebounds too quickly or uncontrollably, try adjusting the rebound setting to a slower position. Ensure that the shock is not set to too low of a rebound, which can lead to instability.
    • If the problem persists, check for any issues with the internal damper or air chamber.
  3. Unusual Sounds:
    • A knocking or clunking sound during compression could indicate that the shock is not properly lubricated or that debris has entered the shock body. Clean the shock thoroughly and check the seals.
  4. Shock Not Moving Smoothly:
    • If the shock feels stiff or jerky, check for any dirt or contamination around the seals. A lack of proper lubrication can also cause stiffness. Apply suspension grease and check the shock’s internal condition.

Customization and Optimization of the TTX2Air Rear Shock

The TTX2Air offers a wide range of customization options to help you tailor the suspension to your specific needs:

  1. Spring Rate Selection:
    • The air spring in the TTX2Air is highly adjustable. Riders can fine-tune the spring rate to their body weight, riding style, and terrain preferences. Customizing the spring rate will result in a more efficient and comfortable ride.
  2. Low-Speed Compression:
    • Adjusting the low-speed compression affects pedaling performance. By fine-tuning this setting, you can ensure that your bike performs optimally on both rough trails and smoother sections.
  3. High-Speed Compression:
    • The high-speed compression adjustment helps in tackling fast impacts such as drops or jumps. By optimizing this, riders can maintain a more controlled feel during aggressive descents or technical trail features.
  4. Lockout Function:
    • The lockout function is ideal for riders who need to switch between different terrains, such as on mixed trails where climbing is involved. You can quickly engage the lockout to prevent unnecessary shock movement when pedaling on flat surfaces.

Compatibility of the TTX2Air Rear Shock

The TTX2Air rear shock is designed to be compatible with a wide range of mountain bike frames, particularly those with a conventional rear shock mounting system. However, compatibility with other drivetrain components and frame geometries should be considered:

  1. Bike Frame Compatibility:
    • Ensure that your frame’s shock mount dimensions are compatible with the TTX2Air. The shock’s eye-to-eye length and stroke must match the frame’s design for proper fitment.
    • The shock is also optimized for modern bike geometries, providing great performance in long-travel suspension frames.
  2. Drivetrain Compatibility:
    • The TTX2Air works seamlessly with a wide range of drivetrains, from entry-level to high-end setups. Its adjustability and performance make it a great choice for riders seeking to optimize their bike’s suspension without being restricted by the drivetrain choice.
  3. Other Components:
    • Consider pairing the TTX2Air with Öhlins’ other suspension products for a fully optimized ride. The performance benefits are often maximized when all suspension components are from the same brand, as they are engineered to work in harmony.
