FUNN valve cap for FOX 36/38 forks

The best suspension upgrade ... for the space above your head.

You’ve set the sag, checked your tyre pressure and adjusted the rebound. But what about your nerves before the ride?

Meet the NOS air fork valve cap—the world’s first mountain bike component designed exclusively for the rider, not the bike. This replaceable air valve cap, standing for Neural Overload Soother, features a fully rotational, tactile knob that provides zero mechanical fork adjustment but 100% satisfaction for your fingers.

Waiting for your crew at the trailhead? Looking at a gnarly rock garden? Just reach down and twist the NOS cap. The smooth, satisfying rotation gives your hands something to do, channelling pre-descent adrenaline into pure focus.
