Installation of TTX22M Coil Rear Shock

Installing the Öhlins TTX22M Coil Rear Shock requires a solid understanding of bike suspension systems. Proper installation ensures that the shock delivers its full potential in terms of performance and durability.

Tools Required:

  • 8mm, 10mm, and 12mm wrenches
  • Torque wrench [paid link] (with proper torque settings)
  • 2.5mm, 3mm, and 5mm Allen wrenches [paid link]
  • Suspension grease
  • Shock pump (for initial setup)
  • Soft cloth or rag
  • Safety glasses and gloves

Step-by-Step Installation:

  1. Remove the Old Shock: Begin by safely lifting the bike and removing the rear wheel. Use a 5mm Allen wrench [paid link] to detach the existing rear shock from the frame. Be sure to keep the mounting hardware as you will need it for the installation of the TTX22M.
  2. Prepare the New Shock: Clean the mounting area and apply a thin layer of suspension grease to the shock bushings or bearings. This helps prevent creaking and ensures smooth motion.
  3. Attach the Shock: Align the TTX22M Coil with the mounting points on the frame. Using the appropriate tools, install the mounting hardware and tighten it to the recommended torque specifications (typically 250–300Nm, depending on the model).
  4. Set the Spring Rate: Use a shock pump to set the spring preload and sag according to your weight and riding style. It’s important to adjust this setting to ensure proper suspension travel and responsiveness.
  5. Reinstall the Rear Wheel: Once the shock is installed, carefully reinstall the rear wheel and check that everything is securely fastened.
  6. Test the Suspension: Perform a few test compressions on the shock to ensure it operates smoothly. Verify that no parts are rubbing or interfering with the frame.

Adjustment and Tuning of TTX22M Coil Rear Shock

The TTX22M Coil Rear Shock is known for its precise adjustability, offering a wide range of tuning options to tailor the ride to your preferences.

Key Adjustment Features:

  • Rebound Damping: This adjustment controls how quickly the shock returns after compression. Slower rebound is beneficial on rough terrain, while faster rebound is more suited to smoother tracks.
  • Compression Damping: You can adjust the low-speed and high-speed compression damping to control how the shock handles impacts and smooths out rough sections of the trail. Low-speed compression is adjusted for general ride comfort, while high-speed compression controls sudden hits and big impacts.
  • Spring Preload: Adjust the preload to ensure the correct sag for your weight. Preload affects how much the shock compresses initially, which directly influences the comfort and responsiveness of your ride.

Step-by-Step Adjustment:

  1. Rebound Damping: Use the rebound adjuster on the shock to fine-tune the rebound speed. Start by setting it to the middle range and adjust according to the feedback you feel during your test ride.
  2. Compression Damping: Begin with the low-speed compression dial set in the middle and adjust according to the terrain you are riding. For more aggressive riders or technical trails, increase the compression to control excessive travel. For smoother riding, dial it back to allow for more suspension movement.
  3. Spring Preload: Adjust the preload by turning the adjuster on the shock’s spring until you achieve the desired amount of sag. The correct sag should be approximately 25-30% of the shock’s total travel. This ensures that the shock is neither too stiff nor too soft for optimal performance.

Maintenance of TTX22M Coil Rear Shock

Proper maintenance of the TTX22M Coil Rear Shock ensures its longevity and consistent performance. Regular service intervals and care can extend the shock’s lifespan and maintain its performance characteristics.

General Maintenance Steps:

  1. Cleaning the Shock: After each ride, wipe down the shock with a soft cloth to remove dirt, mud, and debris. Pay special attention to the shock’s seals and bushings, as they can accumulate grime that may lead to wear over time.
  2. Inspecting the Shock for Leaks: Check for any signs of oil leakage around the shock body, seals, or bushings. If you notice any leakage, it may indicate that the shock needs servicing.
  3. Lubricating the Shock: Apply a small amount of suspension-specific grease to the shock’s bushings or mounting hardware. This will ensure that the shock moves smoothly and prevent creaking noises.
  4. Spring Replacement: If the spring becomes damaged or if you wish to change to a different spring rate, replace it by carefully disassembling the shock. Consult the manufacturer’s manual for proper spring replacement instructions.
  5. Service Intervals: The TTX22M requires regular servicing, typically every 50-100 hours of riding, or at least once a year. This includes a complete oil change, seal replacement, and internal inspection to maintain peak [paid link] performance.

Troubleshooting Common Set-Up Issues

When installing or adjusting your TTX22M Coil, you might encounter a few common issues. Here’s how to address them:

1. Shock Bottoming Out: If the shock is bottoming out frequently, it may indicate that the spring rate is too soft for your weight or riding style. Try adjusting the spring preload or upgrading to a stiffer spring.

2. Excessive Rebound Speed: If the shock rebounds too quickly, it may be due to an improper rebound setting. Adjust the rebound damping to a slower setting and check if the problem is resolved.

3. Poor Ride Quality: If the ride feels harsh or unresponsive, it could be a result of high compression settings. Dial back the compression damping, particularly the high-speed compression, for a smoother ride.

Customization and Optimization for Better Performance

The TTX22M Coil Rear Shock offers multiple options for customization and optimization based on rider needs and preferences.

Customization Options:

  • Spring Rate: Choosing the right spring rate is crucial for achieving proper suspension performance. Riders can opt for a stiffer or softer spring depending on their weight and riding conditions.
  • Damping Settings: Fine-tuning the rebound and compression damping can dramatically alter the feel of the shock. By experimenting with different settings, riders can optimize the shock for different terrains, from downhill trails to cross-country rides.

Optimizing for Performance:

  • Adjusting for Terrain: For more aggressive riding, increase the high-speed compression damping and adjust the rebound to suit the terrain. On smoother trails, reduce compression damping for a plush feel.
  • Ride Feel: To achieve a more responsive ride, reduce the sag slightly and increase the spring preload. Conversely, increasing sag can improve comfort over rough terrain.

Compatibility with Other Drivetrain Components

The TTX22M Coil is designed to work seamlessly with a wide range of modern bike frames and drivetrains. However, compatibility depends on the frame’s shock mount configuration and rear suspension design.

Key Considerations:

  • Mounting Hardware: Ensure the shock’s eyelet and stroke length are compatible with your bike frame.
  • Spring Rate Selection: Different drivetrain setups, weight distributions, and riding styles may require different spring rates for optimal performance. It’s essential to select the appropriate spring for your specific needs.

Comparison with Similar Models

When considering the TTX22M Coil, it’s essential to compare it with similar rear shocks to ensure it fits your requirements.

TTX22M Coil vs. Fox DHX2:

  • The TTX22M is known for its more refined damping system and superior build quality, while the Fox DHX2 offers slightly more adjustability in terms of compression and rebound.
  • The Öhlins model is often preferred for smoother, more consistent performance in technical terrain, while the Fox DHX2 may be better for aggressive riders seeking greater customization.

TTX22M Coil vs. RockShox Super Deluxe Coil:

  • The RockShox Super Deluxe Coil is a slightly more budget-friendly option, but it lacks the damping precision and smoother performance of the TTX22M.
  • For riders looking for a higher level of performance and durability, the Öhlins shock outperforms the RockShox in rough and demanding conditions.
