With the DebonAir Upgrade Kit, your fork gets a new air shaft. This was newly developed by Rock Shox and is installed as standard in models from 2019. A metal base plate with integrated sliding bushing and a new air piston reduce friction to a minimum. An enlargement of the negative air chamber ensures improved responsiveness and more traction. With this DebonAir upgrade, you bring the air unit of your suspension fork up to the latest state of the art.
