Maintaining the TTX2Air rear shock from Öhlins is essential to ensuring a smooth, high-performance ride. While servicing a rear shock might seem intimidating, with the right tools and knowledge, you can easily perform routine maintenance and repairs without a mechanic. This guide covers everything from installation and adjustments to troubleshooting common issues and optimizing performance. Whether you are a beginner or experienced cyclist, this step-by-step approach will help you take care of your TTX2Air rear shock.
Installation of the TTX2Air Rear Shock
Installing the TTX2Air rear shock properly is crucial for optimal performance. Incorrect installation can lead to poor handling and increased wear. Follow these steps to install the shock on your bike:
- Preparation: Ensure your bike is properly supported and stable before you begin. Use a bike stand [paid link] to keep the frame steady.
- Remove the Old Shock: Use the appropriate tools to remove the old rear shock. You may need to detach the linkage or any components that are connected to the shock.
- Install the TTX2Air:
- Slide the TTX2Air shock into place, aligning it with the frame’s shock mounts.
- Tighten the mounting bolts with the correct torque values. Be sure to follow the specifications provided by Öhlins to avoid over-tightening.
- Check Alignment: Ensure that the shock is aligned properly with the suspension linkage and the frame to prevent misalignment during use.

Adjusting the TTX2Air Rear Shock
Proper adjustment of the TTX2Air rear shock can significantly improve your riding experience. The shock offers several tuning options, including rebound, compression, and air pressure. Here’s how you can adjust them:
Air Pressure
The air pressure is the most critical adjustment for setting up the shock to your weight and riding style. Here’s how to set it:
- Check the rider’s weight: Start by referencing Öhlins’ recommended air pressure for your body weight.
- Use a shock pump: Attach the shock pump to the valve and adjust the air pressure according to the manufacturer’s recommendation.
- Check sag: Sit on the bike and check the sag, which is the amount the shock compresses under your body weight. Adjust the air pressure as necessary to achieve the correct sag.
Rebound Adjustment
The rebound adjustment controls how quickly the shock returns to its original position after compression. To adjust it:
- Locate the rebound knob: The rebound adjuster is typically found on the bottom of the shock.
- Turn the knob: Adjust the knob to make the shock rebound slower (turn clockwise) or faster (turn counterclockwise). A slower rebound may be preferred for aggressive riders, while a faster rebound is better for lighter riders or smoother trails.
Compression Adjustment
The compression setting controls how the shock responds to impacts. Adjusting it to your riding style is important for comfort and control:
- Locate the compression adjuster: This is often found near the top of the shock.
- Turn the knob: Turn the knob to increase (clockwise) or decrease (counterclockwise) compression damping. Softer compression is better for rough trails, while firmer compression works for smoother surfaces.
Routine Maintenance for the TTX2Air Rear Shock
Routine maintenance will keep your TTX2Air rear shock functioning optimally and prevent damage. Here’s how to perform regular maintenance:
Cleaning
Regular cleaning ensures that dirt and debris do not affect the performance of the shock. Follow these steps to clean your TTX2Air:
- Use a soft cloth: After every ride, wipe down the shock with a soft, damp cloth to remove dirt and debris.
- Check for damage: Inspect the shock’s seals and shaft for any signs of wear or damage. Replace seals if necessary.
- Avoid harsh chemicals: Do not use harsh chemicals or solvents, as they can degrade the shock’s components. Use water and mild soap only.
Lubrication
Lubricating the shock components helps to maintain smooth movement and prevent corrosion:
- Check shock seals: Make sure the seals are lubricated. Apply a small amount of suspension oil to the seals if needed.
- Inspect and replace oil: Every few months, it’s important to check the oil inside the shock and replace it if it has degraded. Refer to Öhlins’ service manual for the correct oil type.
Troubleshooting Common Issues
Even with proper installation and maintenance, you may encounter some issues with your TTX2Air rear shock. Here’s how to troubleshoot common problems:
Problem: Lack of Rebound or Slow Rebound
If the rebound is too fast or too slow, it can affect your control and comfort on the bike. Here’s what to check:
- Check the rebound setting: Ensure the rebound knob is set correctly. If the rebound is too slow, turn the knob counterclockwise. If it is too fast, turn it clockwise.
- Air pressure: Incorrect air pressure can also affect the rebound speed. Check and adjust the air pressure based on your weight.
Problem: Leaking Air or Oil
If the shock is leaking air or oil, it indicates a problem with the seals:
- Inspect seals: Examine the shock seals for any visible damage or wear. If you notice any cracks or cuts, you will need to replace the seals.
- Check for oil leaks: Oil leakage around the shock body usually means the internal components need to be serviced. In this case, contact a professional if you don’t feel comfortable disassembling the shock.
Problem: No Suspension Travel
If the shock is not compressing or the suspension travel feels stiff, it could be caused by incorrect air pressure or a fault in the damper system:
- Check air pressure: Ensure that the air pressure is set correctly for your weight.
- Check damper settings: Make sure the compression and rebound settings are not set too firmly, causing the shock to feel stiff.
Customization and Optimization
Optimizing your TTX2Air rear shock for better performance is crucial for tailoring the ride to your specific needs. Below are some tips for further customization:
- Adjust air pressure based on terrain: For smoother trails, use less air pressure for a softer ride. For rougher, more technical trails, increase air pressure to provide better support.
- Use the compression adjustment to fine-tune for different riding conditions: Softer compression for technical trails will allow the shock to absorb bumps more effectively, while firmer compression will provide stability on smooth trails.
- Fine-tune rebound: Adjust the rebound to match your riding style. A faster rebound may feel more responsive, while a slower rebound can help you maintain control on rough terrain.
Comparing the TTX2Air with Other Rear Shocks
When choosing a rear shock, it’s important to compare it with other models to ensure you’re making the best decision for your bike and riding style. The TTX2Air is designed for high-performance mountain biking, offering a balance between smoothness and durability. Here’s how it compares to other models:
- Compared to the Fox Float X2: The TTX2Air offers slightly more customization options for compression and rebound, providing finer tuning for different terrains. However, the Float X2 might be more suitable for riders who prefer a simpler setup with less adjustment complexity.
- Compared to the RockShox Super Deluxe: The TTX2Air tends to be more durable and offers better damping control. The RockShox, while effective, doesn’t match the fine-tuning range of the Öhlins shock.
Compatibility with Other Drivetrain Components
The TTX2Air rear shock is designed to work with a variety of drivetrain systems, but ensuring compatibility is key for optimal performance. The shock should be compatible with most modern full-suspension bikes with rear linkage designs, provided the correct mounting hardware is used. Always ensure that the shock is the correct size and that it fits your bike’s suspension design. The shock’s air pressure can be adjusted to match the weight and riding style, regardless of drivetrain components.
