In recent years, the air chamber has changed on various FOX & ROCK SHOX suspension forks (FOX EVOL & RS DebonAir). A new AWK piston has been developed to ensure that your AWK works perfectly with the new air systems. This piston increases the AWK's escape chamber volume and reduces the main chamber of the suspension fork. This achieves an optimal size ratio of all air chambers.
This piston is compatible with all FOX EVOL & ROCK SHOX DebonAir as well as with suspension forks converted to EVOL/DebonAir.
