The Öhlins TTX22M Trunnion [paid link] Rear Shock is a high-performance component designed for riders seeking superior suspension and control. To get the most out of your TTX22M, it’s essential to keep it well-maintained and perform any necessary adjustments to optimize performance. This guide will provide you with the knowledge you need to install, adjust, maintain, troubleshoot, and optimize your rear shock, ensuring it lasts for years to come.
Installation of the TTX22M Trunnion Rear Shock
Installing your TTX22M Trunnion [paid link] Rear Shock requires precision and care. Follow these steps to ensure a proper fit and installation.
1. Remove the Old Rear Shock
Before installing your TTX22M, you’ll need to remove the old shock. Begin by loosening the bolts that secure the shock to the frame and linkage. Make sure to keep all hardware in a safe place for reuse.
2. Install the TTX22M Trunnion Rear Shock
- Place the shock into the frame’s mounting point, ensuring it aligns with the trunnion mount.
- Secure the shock by tightening the bolts to the recommended torque settings (typically around 40–45 Nm).
- Double-check the alignment of the shock to avoid misalignment, which could lead to premature wear.
3. Reconnect the Linkage
Reconnect the shock to the rear linkage and tighten the bolts to secure the rear end. Ensure the linkage moves freely without binding.
4. Check for Proper Functionality
Once installed, compress the shock by hand and check for any unusual resistance or noises. If you feel any issues, the shock may require further inspection or service.
Adjusting the TTX22M Trunnion Rear Shock
The TTX22M offers various adjustments to suit your riding style and terrain. These adjustments will help you achieve optimal suspension performance and comfort.
1. Compression Adjustment
The compression damping controls how quickly the shock compresses when hitting obstacles. The TTX22M features an external adjustment dial, allowing you to fine-tune compression settings. A firmer compression setting is ideal for aggressive riding, while a softer setting works better for smoother trails.
2. Rebound Adjustment
The rebound damping controls how quickly the shock returns to its original position after compression. Too slow, and you’ll experience a sluggish feel; too fast, and the shock may bounce. Adjust the rebound using the dial at the base of the shock to achieve a comfortable return rate.
3. Air Pressure Adjustment
Air pressure is critical for achieving proper sag and suspension travel. Use a high-quality shock pump to adjust the air pressure to the recommended settings based on your weight and riding style. Correct air pressure helps maintain the shock’s responsiveness and prevents bottoming out.
4. Volume Spacers
Volume spacers are essential for adjusting the shock’s progressiveness. Adding spacers increases the ramp-up at the end of the stroke, which is helpful for preventing bottom-outs. If you’re a heavier rider or frequently ride aggressive trails, consider adding spacers to optimize performance.
Maintenance of the TTX22M Trunnion Rear Shock
Regular maintenance will extend the life of your TTX22M and keep it functioning at its peak [paid link]. Perform these tasks at regular intervals to ensure long-lasting performance.
1. Cleaning the Shock
After each ride, clean the shock to remove dirt, debris, and moisture that could damage seals and bearings. Use a mild detergent and warm water, then dry the shock thoroughly.
2. Checking for Leaks
Periodically check for any signs of oil leakage around the shock’s seals and body. Oil leaks can indicate that the seals are worn or damaged, and it’s crucial to address this issue promptly to prevent further damage.
3. Lubricating the Shock
Apply lubrication to the shock’s moving parts, such as the shaft and seals. This reduces friction and prevents excessive wear. Be cautious not to over-lubricate, as excess oil can attract dirt and cause damage.
4. Service the Shock Internally
Öhlins recommends servicing the shock every 50-100 hours of riding or at least once a year, depending on usage. Internal servicing should be done by a professional to maintain the shock’s performance. It involves disassembling the shock, inspecting the internals, and replacing any worn components.
Troubleshooting Common TTX22M Trunnion Rear Shock Issues
Even the best components may encounter issues from time to time. Here’s how to troubleshoot common problems with the TTX22M.
1. Excessive Rebound or Sluggishness
If the shock feels too bouncy or too slow when returning to its extended position, you may need to adjust the rebound setting. If adjusting the rebound doesn’t resolve the issue, check the air pressure and compression settings to ensure they’re within the recommended range.
2. Bottoming Out
Bottoming out occurs when the shock compresses fully, often resulting in a harsh ride. If this happens frequently, increase the compression damping or add volume spacers to make the shock more progressive. You may also want to check that the air pressure is set correctly.
3. Noisy Shock
If your shock is making unusual noises, it could indicate insufficient lubrication or worn-out seals. Check the shock for any visible damage and apply lubrication to the moving parts. If the noise persists, the shock may need internal servicing.
4. Leaking Oil
If you notice oil leaking from the shock, it’s a sign that the seals may have worn out. Worn seals should be replaced promptly to avoid further damage to the shock. If you’re unsure how to replace the seals, take the shock to a professional for servicing.
Customization and Optimization of the TTX22M Trunnion Rear Shock
Customizing the TTX22M to your specific riding style and preferences can elevate your performance. Here are a few tips for optimizing the shock:
1. Adjusting Air Pressure Based on Terrain
On smoother terrain, you can run slightly higher air pressure for a more responsive ride. For rougher trails with more aggressive features, lower air pressure will provide more travel and improve traction.
2. Fine-Tuning Compression for Different Riding Styles
For riders who focus on downhill racing or aggressive trail riding, a firmer compression setting will provide better control during high-speed descents. Conversely, riders focused on cross-country or endurance riding may prefer a softer compression setting for a more comfortable ride over longer distances.
3. Consider Upgrading to a Custom Tune
If you’re an experienced rider looking to get the most out of your shock, you can have a custom tune done. This involves adjusting the internals of the shock to better suit your weight, riding style, and the terrain you frequent.
Comparison with Similar Models
When choosing a rear shock, it’s essential to consider how the TTX22M stacks up against similar models in the market. Compared to other high-performance shocks in the same price range, the TTX22M offers excellent durability, easy adjustments, and a progressive feel that makes it suitable for both aggressive riders and those seeking comfort.
TTX22M vs. Fox Float X2
Both the Öhlins TTX22M and the Fox Float X2 are renowned for their performance. However, the TTX22M stands out with its more refined compression adjustment and more responsive damping system. While the Fox Float X2 offers a similar range of adjustability, the TTX22M provides a smoother, more controlled ride, especially on rough terrain.
TTX22M vs. RockShox Super Deluxe
The RockShox Super Deluxe is another competitor in the rear shock market. The TTX22M offers a more progressive and precise feel, while the Super Deluxe tends to offer a more plush and forgiving ride. If you prioritize precision and customization, the TTX22M is a better choice.
Compatibility with Other Drivetrain Components
The TTX22M Trunnion Rear Shock is compatible with a wide range of drivetrain components, but it’s essential to ensure that the shock’s specifications match your bike’s requirements. The trunnion mount system provides better linkage geometry and optimized suspension travel, making it ideal for a wide range of modern bikes.
When pairing the TTX22M with other drivetrain components, ensure that the suspension travel and geometry align with the front fork and other shock components. If you’re unsure, consult the manufacturer’s guidelines for compatibility with other suspension components.
By following this guide, you can extend the life of your TTX22M Trunnion Rear Shock and enjoy top-notch performance on every ride. Regular maintenance, fine-tuning adjustments, and quick troubleshooting will keep your shock performing at its peak [paid link] for many years.
