A bit of fun for your fork. The NOS (Neural Overload Soother) cap swaps your stock air valve cap for an oversized CNC dial you can spin while you wait at the trailhead. It changes nothing about your suspension, but it is easier to grip and looks the part.

Highlights

  • Replaces the stock air-side valve cap
  • Free-spinning indexed dial with no mechanical adjustment
  • Oversized for easy removal with gloves on when you check pressure
  • CNC-machined aluminium, anodised finish
  • F-Type for Fox 36, Fox 38 (pre-2027) and other listed forks, 22g

What it does, and what it does not

Turning the dial does not change air spring volume, pressure or damping; it is there to keep your hands busy at the trailhead. The dial is isolated from the valve core, so spinning it will not let air out. Install by hand: unscrew the stock cap and thread the NOS cap on finger-tight, no tools needed.

Compatibility & fit

  • Fox 36
  • Fox 38 (pre-2027)
  • Marzocchi Z1, Z2 and DJ

  • DVO Onyx and Diamond with a hex top cap
  • Not compatible: Fox 38 (2027), Fox Podium, Fox 40 and all coil forks
  • Fox 34: the thread matches, but FUNN does not recommend it as the oversized cap looks bulky on a 34mm stanchion
  • F-Type and RS-Type are not interchangeable; choose the type for your fork
