How 2 Setup Fox DHX2 coil shock

Summary

This video provides a comprehensive guide on tuning the DHX2 shock for optimal performance. The presenter walks through the process of selecting the right spring rate based on body weight, emphasizing the importance of dynamic sag and shock adjustments. With hands-on demonstrations, viewers learn how to fine-tune rebound and compression settings to achieve a smoother, more responsive ride, especially on blue flow trails. The presenter also explains how a faster rebound setting, paired with added compression, enhances the shock's performance. Overall, the video offers practical insights for cyclists looking to maximize their suspension setup.

Takeaways

• 😀 Start by using a spring calculator to find the right spring rate for your weight and bike setup (e.g., 220 lb rider with 160 mm travel).
• 😀 For DHX2 shocks, overspringing (28% sag) is often preferred to achieve better performance, especially for a linear coil shock.
• 😀 Static sag is useful for a quick setup, but dynamic sag (how the shock behaves while riding) is more critical for performance on the trail.
• 😀 The DHX2 shock has a wide range for rebound adjustment, allowing for fine-tuning of the shock’s reaction to trail conditions.
• 😀 Compression adjustment range on the DHX2 is more limited, but using the firm lever can help to fine-tune compression for different terrain.
• 😀 When adjusting suspension, make small incremental changes (e.g., 1-2 clicks) and assess performance on high-speed sections of the trail.
• 😀 Focus on reaching the fastest rebound setting for optimal shock control, balancing it with appropriate compression to maintain stability.
• 😀 The process involves trial and error, so it's recommended to make only three main adjustments before returning to baseline settings.
• 😀 Always verify suspension settings by riding on various trails, from blue flow trails to technical black trails, to ensure the suspension feels balanced and effective.
• 😀 The setup may require fine-tuning for rougher, high-speed terrain by adjusting compression or using the firm compression lever as needed.

Q & A

What is the importance of selecting the correct spring for the DHX2 shock?

Selecting the correct spring is crucial for the shock's performance. It ensures that the suspension is not too soft or too firm, which can negatively affect the bike's handling. A spring that's slightly oversprung, around 28% sag, works best for the DHX2 shock, especially since it is a linear coil shock.

How do you calculate the right spring rate for your weight?

You can use a spring calculator like the one on TF Tuned. Input your weight, travel length, and stroke length to determine the appropriate spring rate. For a 220 lb rider on a 160 mm travel bike, a 600 lb spring is a common recommendation.

What is the difference between static sag and dynamic sag?

Static sag is measured when the bike is stationary, while dynamic sag is assessed when the bike is in motion. Dynamic sag is more important for tuning, as it reflects how the shock behaves during actual riding conditions.

What is the 'rule of thirds' in suspension setup?

The 'rule of thirds' involves making only three adjustments to your suspension settings before returning to a baseline. Start with middle settings, then test and adjust incrementally based on how the bike feels during the ride.

What is the effect of adjusting the rebound too slowly on the DHX2 shock?

If the rebound is set too slowly, it will feel like the shock is locked out, making the ride harsh and unresponsive. The rebound range on the DHX2 is large, so adjusting it to be faster helps achieve better performance and smoother handling.

How do compression and rebound settings interact when tuning suspension?

Rebound and compression settings are interrelated. If you increase rebound speed to make the shock feel more responsive, you may need to add compression to slow it down to maintain balance and prevent the shock from becoming too 'bouncy.'

Why is testing suspension on high-speed sections important?

High-speed sections, like jumps and fast terrain, are where the suspension is put to the test. These sections provide more accurate feedback on how the shock handles forces, helping you fine-tune the rebound and compression settings for better performance.

What is the role of the firm lever on the DHX2 shock?

The firm lever on the DHX2 shock allows you to adjust the compression to make the suspension firmer. It's useful for specific riding conditions, such as when you're climbing or riding on smoother trails, to prevent excessive sag and improve control.

What happens when the rebound is set too fast on technical trails?

When the rebound is too fast on technical trails, the bike may feel too floaty or unstable, especially on rough or rocky sections. This can be corrected by increasing compression slightly to balance the rebound speed.

What is the significance of verifying suspension settings on unfamiliar terrain?

Verifying your suspension settings on unfamiliar terrain allows you to assess how the bike performs in various conditions. This helps ensure that your adjustments are effective for different types of trails, such as rocky or smooth surfaces, and provides an opportunity to make any final tweaks.
