Installation of the Öhlins TTX1Air Rear Shock

Preparation

Before starting the installation of the TTX1Air rear shock, ensure you have all necessary tools and the correct shock specifications for your bike model. Double-check your bike’s frame to ensure it’s compatible with the TTX1Air’s mounting hardware. The TTX1Air is designed to fit a variety of mountain bike frames, but it’s always best to consult your frame’s manual for compatibility details.

Tools Required

• 5mm and 6mm Allen wrenches [paid link]
• Torque wrench [paid link]
• Shock pump (for air pressure adjustment)
• Shock eyelet bushings (if required)
• Clean cloth

Installation Steps

1. Remove the existing shock: Use the appropriate Allen wrenches [paid link] to remove the bolts securing the existing rear shock to the frame. Carefully remove the shock from its mount.
2. Install the TTX1Air shock: Position the TTX1Air into the shock mounts on your frame. Ensure the shock is properly aligned with the mount and that the mounting hardware is clean and undamaged.
3. Secure the shock: Tighten the mounting bolts to the manufacturer-recommended torque settings, ensuring the shock is firmly in place without over-tightening.
4. Set air pressure: Using a shock pump, adjust the air pressure to the recommended settings based on your weight and riding style. Start with the default pressure range and make adjustments as necessary for a tailored ride.
5. Check the shock’s alignment: Ensure the shock operates smoothly and there is no binding in the suspension travel.

Adjustment of the TTX1Air Rear Shock

The TTX1Air is highly adjustable, allowing riders to fine-tune the suspension for different terrains and riding styles. Here’s how to adjust its key settings:

Compression Damping

• Low-speed compression: This adjustment controls the shock’s response to slower impacts, such as riding over rocks or roots. Turn the low-speed compression knob clockwise to stiffen the shock, or counterclockwise to soften it for a more active feel.
• High-speed compression: This controls the shock’s reaction to faster, more aggressive impacts like drops or large hits. Adjusting the high-speed compression helps prevent bottoming out when hitting hard obstacles.

Rebound Damping

• Rebound adjustment: The rebound knob controls how quickly the shock returns after compressing. A slower rebound will offer a smoother ride, particularly on rough terrain, while a faster rebound will feel more responsive. Adjust this knob based on the specific trail conditions and your riding preference.

Air Spring Pressure

• Adjust the air spring pressure based on rider weight and preferred ride characteristics. The TTX1Air has an adjustable air chamber that can be set to provide optimal support and a smooth feel throughout the suspension stroke. Experiment with different pressures to find the ideal balance of plushness and support.

Maintenance of the TTX1Air Rear Shock

Regular maintenance of the Öhlins TTX1Air ensures optimal performance and longevity. Here’s a breakdown of key maintenance tasks:

Routine Cleaning

• Clean the shock after every ride to prevent dirt and debris from accumulating. Use a clean, soft cloth and water to wipe down the shock body, avoiding any harsh chemicals that could damage the seals or internal components.

Air Pressure Check

• Check the air pressure regularly, especially after riding. Air pressure can drop over time, and adjusting it ensures the shock remains at optimal performance. Use a shock pump to maintain the correct air pressure as outlined in the user manual.

Seal Maintenance

• Inspect the shock’s seals for any signs of wear or damage. If oil leakage is noticed, it may be time for a seal replacement. Regularly lubricate the seals with suspension oil to ensure smooth operation and reduce friction.

Annual Overhaul

• While the TTX1Air is a high-quality, durable shock, an annual service is recommended. This involves a thorough disassembly and inspection of internal components. It’s best to have this done by a professional technician, as it requires specialized tools and expertise.

Troubleshooting Common Set-Up Issues with the TTX1Air

Although the Öhlins TTX1Air is a high-performance shock, certain issues can arise during installation or use. Here are some common problems and how to address them:

Shock Bottoming Out

• Cause: Insufficient air pressure or too soft compression settings.
• Solution: Increase the air pressure to match your body weight and riding style. Additionally, adjust the compression settings to a stiffer setting, especially for high-speed compression.

Excessive Rebound or Poor Control

• Cause: Incorrect rebound damping settings or too high air pressure.
• Solution: Adjust the rebound damping to a slower setting for better control. If rebound is too fast, the shock may feel bouncy or unstable. Also, check and adjust air pressure to avoid a harsh ride.

Poor Performance on Small Bumps

• Cause: Low air pressure or too stiff compression settings.
• Solution: Lower the air pressure slightly to increase sensitivity to smaller impacts. Reduce the compression damping, especially low-speed compression, to allow the shock to react more easily to smaller bumps.

Customization and Optimization for Better Performance

The TTX1Air rear shock offers a wide range of customization options, allowing riders to fine-tune the shock to their riding style and terrain.

• Personalized Air Pressure: Based on body weight, riding style, and terrain, air pressure can be adjusted for a plush feel or firmer support.
• Compression Tuning: For technical riding or aggressive descending, adjusting the compression settings allows the shock to handle larger impacts more effectively while maintaining comfort on small bumps.
• Rebound Speed: Riders can adjust the rebound speed to suit their preferred suspension feel, with faster rebound for aggressive riders and slower rebound for smoother, more controlled descents.

Comparison with Similar Models

When considering the TTX1Air, it’s important to compare it with other high-end rear shocks on the market to determine if it is the best option for your needs.

TTX1Air vs. Fox Float X2

• The Fox Float X2 is known for its excellent small-bump sensitivity and a broad range of adjustability, but the TTX1Air typically offers superior damping control and better performance in technical terrain. The TTX1Air’s air spring system is also more responsive for heavier riders or those looking for a more aggressive setup.

TTX1Air vs. RockShox Super Deluxe Ultimate

• The RockShox Super Deluxe Ultimate is a great all-rounder with exceptional performance on most trails. However, the TTX1Air tends to have more precise control over the high-speed compression and rebound damping, making it the preferred choice for downhill riders or those tackling extreme terrain.

Understanding Compatibility with Other Drivetrain Components

The TTX1Air is designed to be compatible with most mountain bike frames, but there are a few considerations regarding drivetrain compatibility:

• Frame Compatibility: Ensure that your bike’s rear triangle is designed to work with a shock of the TTX1Air’s dimensions. The shock’s eyelet size and mounting configuration must match the frame’s design.
• Drivetrain Synergy: The rear shock doesn’t directly interact with the drivetrain, but having a compatible suspension system enhances overall bike handling. For example, pairing the TTX1Air with a well-matched fork, like the Öhlins RXF 36, ensures a smoother ride and better suspension performance across both ends of the bike.

The Öhlins TTX1Air is one of the top rear shocks available for mountain bikers, offering exceptional adjustability and performance across various terrains. It’s designed for riders who demand the highest level of control and customization, especially in technical and aggressive riding conditions. Whether you’re a seasoned pro or an enthusiastic rider, the TTX1Air delivers the kind of performance that can significantly enhance your mountain biking experience.
