Installation of the TTX22M Coil Rear Shock

Proper installation of your TTX22M Coil rear shock is critical for its performance. Follow these steps to ensure a smooth setup:

1. Remove the old rear shock: If you’re replacing an existing shock, begin by removing it from the frame. Use appropriate tools to unscrew the shock bolts and carefully detach it.
2. Install the TTX22M Coil shock: Position the TTX22M shock into the mount on the frame, ensuring the shock’s eyelet is aligned with the mounting points.
3. Secure the bolts: Tighten the mounting bolts with a torque wrench [paid link] to the manufacturer’s specified torque setting to ensure a secure attachment.
4. Install the coil spring: The TTX22M comes with an adjustable coil spring. Place it onto the shock, ensuring it’s seated correctly.
5. Check for free movement: After installation, check that the shock moves freely without any interference from the frame or other components.

Adjustment of the TTX22M Coil

The TTX22M Coil rear shock offers a wide range of adjustments for riders to fine-tune their suspension settings. These adjustments are crucial for optimizing comfort and performance based on riding style, weight, and terrain. The following sections break down the primary adjustments and how to fine-tune them.

Rebound Adjustment

The rebound control adjusts how quickly the shock returns to its original position after compression. Fine-tuning this setting will ensure you maintain control of the bike during high-speed descents.

• To adjust the rebound: Locate the rebound adjuster knob on the shock body. Turning it clockwise will slow the rebound, while turning it counterclockwise will speed it up.
• Ideal setting: Set the rebound so that the shock returns quickly but without causing excessive bouncing. A good rule of thumb is to set it so that the shock fully extends without feeling too harsh or overly sluggish.

Compression Adjustment

Compression damping controls how the shock resists being compressed under force, providing support when hitting bumps and drops. There are two types of compression adjustment: high-speed and low-speed.

• Low-speed compression: Adjusts the shock’s response to smaller, slower bumps and pedaling forces. This setting is essential for providing a stable, controlled ride.
• High-speed compression: Determines how the shock responds to bigger impacts and high-speed forces. This adjustment is crucial for aggressive riding and technical descents.

To adjust, turn the high-speed and low-speed compression dials on the shock body. Turning them clockwise will stiffen the compression, while turning counterclockwise will make it softer.

Spring Preload

The spring preload adjusts the initial tension of the coil spring, affecting the shock’s overall firmness and sag. Proper preload is vital for maintaining optimal ride height and suspension performance.

• To adjust preload: Use a spanner tool to turn the preload collar clockwise to increase tension or counterclockwise to decrease it. Adjust the preload so that the shock’s sag is within the recommended range, typically around 25-30% of the shock’s total stroke.

Maintenance of the TTX22M Coil

Regular maintenance is essential to keep your TTX22M Coil rear shock performing at its best. Here are some key maintenance tasks:

Lubrication

• Check the shock seals: Inspect the seals for any signs of wear or damage. If the seals are leaking oil, they will need to be replaced.
• Apply fresh oil: Use the recommended oil to lubricate the shock’s moving parts. Ensure that the oil is clean and properly filled to prevent internal friction and overheating.

Cleaning

• Clean the shock body: Regularly wipe down the shock body and eyelets to remove dirt, grime, and debris that could damage the shock. Use a soft cloth and mild detergent to clean the components.
• Inspect the coil spring: Check the coil spring for any signs of wear, including scratches or cracks. Clean it with a damp cloth to remove dirt.

Air Can Service

While the TTX22M Coil uses a coil spring for suspension, it also includes an air chamber that may require servicing. Periodically check the air pressure in this chamber and top it up if necessary.

Troubleshooting Common Set-Up Issues

Even the best components may experience issues from time to time. Here are a few common problems and how to resolve them:

Shock Bottoming Out

If the shock is bottoming out, it may be due to insufficient compression damping or too much sag. To resolve this issue:

• Increase the compression damping to resist bottoming out on bigger impacts.
• Adjust the preload to reduce sag and maintain proper ride height.

Excessive Rebound

Excessive rebound can cause the shock to feel too bouncy or uncontrolled. To correct this:

• Adjust the rebound to a slower setting, ensuring the shock doesn’t extend too quickly after compression.
• If the rebound is still too fast, check for air in the shock and ensure proper oil levels.

Squeaking or Noisy Shock

If your shock is making squeaking or creaking noises, it may be due to friction between the coil and shock body. To resolve this:

• Apply a small amount of lubricant to the coil and shock body to reduce friction.
• Inspect the shock’s seals for wear or damage, as they could be causing unwanted noise.

Customization and Optimization for Better Performance

Customizing your TTX22M Coil rear shock is crucial for achieving optimal performance on different types of terrain. Here are some key areas to focus on:

Tuning for Different Riding Styles

• Cross-Country Riders: Opt for a stiffer compression setting and minimal rebound to maximize pedaling efficiency and minimize energy loss.
• Enduro or Downhill Riders: A softer compression setting combined with slower rebound will provide more control and comfort when tackling rough, high-speed descents.

Adjusting for Weight and Riding Conditions

The weight of the rider plays a significant role in how the shock performs. Adjusting the preload and damping settings based on your weight will ensure that the shock performs at its best. Additionally, consider the type of terrain you’ll be riding on. Softer settings may be more appropriate for rougher trails, while firmer settings work better on smoother paths.

Comparison with Similar Models

When choosing a rear shock, it’s essential to compare the TTX22M Coil with similar models to determine which one fits your needs. Some common alternatives include the Fox DHX2 and the RockShox Super Deluxe Coil.

• Fox DHX2: Known for its high adjustability, the DHX2 features similar low-speed and high-speed compression adjustments, but the TTX22M Coil offers more precise control over fine-tuning with a wider range of settings.
• RockShox Super Deluxe Coil: While it is often praised for its plush feel, it doesn’t offer the same level of customizable rebound control as the TTX22M Coil, making the Öhlins shock a better option for riders looking for more precise adjustments.

Compatibility with Other Drivetrain Components

The TTX22M Coil rear shock is designed to be compatible with a wide variety of bike frames, but it’s essential to check compatibility with your drivetrain components. For example:

• Bikes with a direct mount frame: Ensure that the shock’s eyelet is compatible with your frame’s mounting standard.
• Suspension linkage systems: Check the shock’s stroke length and eye-to-eye length to make sure it fits within your frame’s suspension linkage system.

By considering these factors, you can ensure that your TTX22M Coil shock works seamlessly with your bike’s drivetrain and suspension system.
