S20 FAQ (8/28)


Is the suspension replaceable?

Yes, be sure to find a suspension thats 240-75 or 240-76.

What suspension comes with the S20?

The S20 will come with DNM RCP-2S with a 750lbs spring, however this is subject to change within the next weeks.

What suspension do you reccommend?

Fox shocks is undoubtedly the best available, Rockshox is also very good however not suitable for EUCs. It’s perfect for good or poor asphalt, not for off-roading. The shortcoming is that it’s prone to bottoming out, it’s easy to hit the bottom when riding on big obstacles, especially for heavier riders.

Although the DNM240-75 is an entry level coil suspension, the 750lb spring is suitable for most riders however for heavier riders we do suggest upgrading to a 1000lb spring if you do want to attempt the extreme.

Many of the shocks available for the S20 Eagle are basically some of the best on the market, with all adjustable compression and rebound dampening.

The adjustable compression dampening is the key to the limit, the blue knob can increase the limit of the S20 allowing it to take on a larger impact. If heavier riders are experiencing bottoming out, there’s a high probability for you to resolve this by adjusting the blue compression dampening. In the same way, light riders can switch to 550lbs spring if they feel that the shock absorber is too hard. You are able to change just the spring and not having to change the entire shock.

Lots of suspensions are readily available on the market as long as they meet the 240-75 or 240-76 you'll be able to fit it into your S20 Eagle.
