HS3

The FERRO USD 36 fork uses the HS3 technology, the unique hybrid
air spring system, already been famous with the appreciated ERA V2.

self-equalizing negative air chamber; HS3 is focused on mid-stroke
support around the dynamic sag position while offering amazing
sensitivity and bottom-out protection
