One of our eagle-eyed readers spotted this prototype shock from Fox out in the wild this afternoon at Mont Sainte Anne. The shock is mounted up to a Santa Cruz V10 and is pretty different from the DHX2 currently in production.
Most notably, the knobs/dials that control the compression and rebound damping seem to be revamped and are now different sizes and in a different position than the current DH shock. The reservoir is also slightly different. Additionally, there's a third dial at the opposite end of the shock near the eyelet. The current DHX2 has independently adjustable high- and low-speed rebound damping - perhaps this prototype does too, but with a different adjuster configuration. It's also possible that the adjuster near the reservoir does something else entirely...perhaps mid-speed damping?
While it's still a prototype, it does seem to be pretty refined so it very likely could be a product that will soon see production...as the DHX3, perhaps?
We reached out to Fox for comment and received the following response:
| In an effort to continually develop highly advanced suspension products, FOX constantly tests prototype components in the field under the world’s best racers. Some of these components – or parts of them – eventually make it into production, many of them do not. Testing in real-world environments, such as in racing applications, is a critical part of how we determine what works best – not only for our professional athletes but ultimately for every rider who puts their trust in FOX products. This field testing protocol is part of our proven and longstanding RAD (Racing Application Development) program.—Sean Estes - Brand Manager, Fox Factory |
If any additional details become available we'll be the first to let you know.
Yes looks like lsc is back on the main piston.
Top red adjuster is likely still hsr
already spotted a few months ago...
Although I would prefer it if they have incorporated some kind of hydraulic bottom out control/progressive damping
No it's not a beginning or end stroke system
It's a velocity sensitive system period.
Quite different from a position sensitive system with zones like a bypass shock.
But you probably haven't worked on both.
Can't get much lsc out of them without cranking down the hsc, the hsc blows open giving a huge hole in the mid speed damling and they hydraulic lock at high speeds.
That's the downside of a poppet based damper
Really all fox's current example of the twin tube has going for it is that the hsr is externally adjustable, meaning you don't have to re shim or as a mfg offer soft medium, and firm tunes. Fox absolutely loves not having to do soft medium and firm tunes. What do you get in return? A shit compression curve. Not a fair trade.
This is why the originators of the twin tube (ohlins) use a hybrid between a de carbon shock and a twin tube in off-road applications, they still use a mid valve and they use a proper shim stack on the base valve/high speed adjuster.
Simply using a shimmed valve in the high speed system like ohlins does will really be an improvement.
It appears that fox is headed that way with this shock, indicated by the apparently larger compression assembly. Fox appears to be keeping the HSR adjuster and judging by its size it's a poppet piston which works decent for rebound.
This will mitigate the downsides of the twin tube design while providing benefits from both designs.
BTW If you think your x2 is good send it to Craig at avalanche for the ssd mod,
You will see that in standard form it's actually garbage
