The new Fox DHX2 shock is already proving to be incredibly successful on the World Cup downhill circuit, and that technology is starting to trickle down to users now in the production models. One such piece of tech is the Rod Valve System (RVS)  which you can see working in the video above.

The RVS damper, which operates with 4 way adjustment, functions similarly to a Cane Creek Double Barrell. The product is based on prototype versions that were used by World Cup downhill racers under the Racing Applications Development (RAD) programme.

Also new is the orange Super Light Steel (SLS) spring. Fox claim this weighs less than a titanium spring due to a thinner wire and fewer coils, the steel is pre-treated so it retains its strength. It can also be retrofitted to old VAN and DHX coil shocks.

The DHX2 is partnered this year by the new Fox X2 air shock which features the same RVS damper system as the DHX2.

Both shocks will set you back £499.99 but it’s worth noting that the DHX2 doesn’t come with a spring. The SLS spring will cost £123 whereas the standard steel spring costs only £39.

The shocks have won five World Cups this year alone (Two for Aaron Gwin, two for Rachel Atherton and one for Greg Minnaar) so their performance quality is more than proven. Don’t think it’s all for downhill though, Fox reckons that the X2 will be light enough to use on hard hitting enduro bikes too.
