  • Torque wrench [paid link]
  • Flathead screwdriver
  • T25 Torx driver
  • Suspension oil
  • Cleaning brush
  • Soft rag
  • Oil catch pan
  • Brake fluid (if applicable)
  • Sealant for suspension forks
  • Bicycle stand

Installation of the TTX22M Coil Fork

Installing the Öhlins TTX22M Coil Fork [paid link] requires careful attention to detail to ensure optimal performance and safety. Follow these steps to properly install your new fork.

Step 1: Preparing the Bike

  • Place your bike on a stand to ensure it is stable and secure during installation.
  • Remove the front wheel and the existing fork by loosening the headset bolts and any brake mount hardware.

Step 2: Installing the Fork

  • Slide the TTX22M fork into the head tube of your frame.
  • Tighten the headset bolts and make sure the fork is straight and aligned with the wheel. Adjust the stem to ensure the handlebars are in the correct position.

Step 3: Attaching the Brake Caliper

  • If your bike has a disc brake system, attach the brake caliper to the fork mounts.
  • Use a T25 Torx driver to tighten the bolts securing the brake caliper in place.

Step 4: Installing the Wheel

  • Once the fork is installed, reinstall the front wheel. Ensure the axle is properly secured.

Step 5: Final Checks

  • Double-check all bolts for proper torque specifications.
  • Test the movement of the fork to ensure it moves smoothly without any binding or unwanted resistance.

Adjusting the TTX22M Coil Fork

Proper adjustment of your Öhlins TTX22M Coil [paid link] Fork is crucial for maximizing performance. The TTX22M features advanced damping systems and customizable settings to cater to your riding style and terrain. Follow these steps for the ideal setup.

Step 1: Adjusting the Air Spring Preload

  • The TTX22M coil [paid link] fork uses a coil spring, but you can adjust the preload to customize the stiffness of the fork.
  • To adjust the preload, use the dedicated tool provided with the fork or a suitable wrench to turn the preload adjuster. Turning it clockwise will increase the preload and make the fork stiffer, while turning it counterclockwise will soften the suspension.

Step 2: Fine-tuning Compression and Rebound Damping

  • The fork comes with separate compression and rebound adjustments to fine-tune your ride.
  • Compression Damping: Adjust the compression setting to control how the fork reacts to impacts. For rough terrains, a firmer compression setting will help the fork absorb big hits. For smoother trails, a softer compression allows for more responsiveness.
  • Rebound Damping: Adjust the rebound damping to control how quickly the fork returns to its original position after compression. Too fast a rebound can cause instability, while too slow a rebound can affect performance. Aim for a balanced setting based on your riding style.

Step 3: Adjusting the Lockout

  • The TTX22M includes a lockout feature, allowing you to reduce unwanted fork movement during pedaling on smooth trails. Use the lockout lever to adjust this setting. Be cautious, as using the lockout too often on rough terrain can negatively affect suspension performance.

Maintenance of the TTX22M Coil Fork

Regular maintenance of the Öhlins TTX22M Coil Fork will ensure its longevity and consistent performance. Follow these guidelines to maintain the fork in optimal condition.

Step 1: Cleaning

  • After each ride, clean the fork with a soft rag to remove dirt, mud, and debris.
  • Use a brush to clean the seals and lower legs of the fork. Be careful not to damage any of the seals during this process.

Step 2: Checking for Leaks

  • Check the fork’s seals for any signs of oil leakage. If you notice any oil around the seals, it may be time to replace them. Replacing seals regularly will prevent dirt and water from entering the fork and causing internal damage.

Step 3: Changing the Oil

  • Regularly replace the suspension oil in your TTX22M fork to maintain damping performance.
  • Drain the old oil into an oil catch pan and carefully refill the fork with the recommended suspension oil.
  • Follow Öhlins’ guidelines for oil levels and types to ensure proper functioning.

Step 4: Replacing the Coil Spring

  • If you notice that your suspension is not performing as expected, it may be time to replace the coil spring.
  • Coil springs can wear out over time, especially if subjected to harsh riding conditions. Choose a replacement spring that suits your weight and riding style.

Step 5: Inspection

  • Periodically inspect the entire fork assembly for wear and tear. Look for cracks in the fork legs, worn-out bushings, or loose bolts. Catching potential issues early can prevent costly repairs down the road.

Troubleshooting Common Set-Up Issues

Even with the best suspension forks, issues can arise during setup. Here are a few common problems with the TTX22M and how to address them.

Issue 1: Insufficient Suspension Travel

  • Possible Cause: Incorrect preload or damping settings.
  • Solution: Adjust the preload and damping settings to match your weight and terrain. Ensure the fork is properly lubricated to allow full travel.

Issue 2: Fork Feeling Too Soft or Too Stiff

  • Possible Cause: Incorrect coil spring or improper preload.
  • Solution: Verify the coil spring rating matches your weight and riding style. Adjust the preload as necessary to fine-tune stiffness.

Issue 3: Unstable Rebound

  • Possible Cause: Incorrect rebound damping setting.
  • Solution: Adjust the rebound to achieve a smooth, controlled return. If the fork rebounds too quickly, increase the rebound damping. If the rebound is too slow, reduce the damping.

Customizing and Optimizing the TTX22M Coil Fork for Better Performance

Optimizing your Öhlins TTX22M Coil Fork can drastically enhance your riding experience. Customization can range from minor adjustments to swapping out parts for more advanced options.

Upgrading to a Different Coil Spring

  • If you feel the suspension is not handling the terrain as efficiently, upgrading to a different coil spring may be necessary. Choose a spring with a higher or lower rating based on your body weight and riding style.

Adding Volume Spacers

  • Volume spacers can be added to the fork to increase progression in the suspension. This modification prevents bottoming out and enhances overall performance on technical trails.

Fine-tuning Damping Settings

  • Use fine-tuning methods, such as changing the damping fluid or adjusting the internal shim stack, to modify the fork’s response to trail conditions. This is often recommended for riders looking to achieve the perfect balance between comfort and performance.

Compatibility with Other Drivetrain Components

The TTX22M Coil Fork is designed to work with a variety of mountain bikes and drivetrain systems, but it’s important to ensure compatibility with your current setup. The fork uses a standard 15mm or 20mm through-axle, and you should verify that your frame and wheelset support these axle sizes. Additionally, ensure that the brake mount matches the size of your brake rotor, whether you use a 160mm, 180mm, or 203mm disc.

Comparison with Similar Models

When comparing the Öhlins TTX22M Coil Fork to other suspension forks on the market, several factors come into play, including performance, adjustability, and price. Here’s how the TTX22M stacks up against some popular alternatives:

Fox 36 Float Factory Fork

  • The Fox 36 is a strong competitor, offering a lighter air-spring system, but it may not provide the same plush coil-spring feel that many riders prefer for downhill racing or aggressive riding.

RockShox Lyrik Ultimate

  • The Lyrik Ultimate offers excellent adjustability and a high-quality air spring, but the TTX22M’s coil spring offers a more consistent ride quality, especially for riders who prioritize control and feel.

DVO Onyx SC D1

  • The DVO Onyx SC D1 [paid link] is another high-performance option, similar in terms of adjustability and performance. However, the Öhlins TTX22M has the edge when it comes to coil spring consistency and rugged [paid link] durability.

Ultimately, the choice between these forks depends on your personal preferences, riding style, and specific needs. The TTX22M stands out in terms of consistent performance and durability, especially for riders who prefer the feel of a coil spring on rough and technical terrain.
