Selva V Airshaft Assembly

Selva V Air Spring

The all-new V air spring uses a floating piston design to reduce friction providing a more consistent feel all the way through the stroke. 

A single air valve is used to inflate both positive and negative air chambers. A unique concentric bypass valve design balances pressure between the chambers making setup simple.

Low-friction design for performance and reliability
Our floating piston design reduces friction throughout the stroke. The small imperfections inherent in metal can create friction at the main seal of the piston. By using an elastic mount which allows the piston to move both radially and axially, it can naturally compensate for these imperfections, reducing friction and providing a more consistent feel all the way through the stroke. 

Concentric bypass valve
A single air valve is used to inflate both positive and negative air chambers. To balance pressure between these chambers the Selva V uses a unique concentric bypass valve design, rather than a conventional bypass port. Repeated passage over a bypass groove can wear out a seal. To compensate for this a stronger, more robust seal is needed, one that inevitably adds friction The concentric bypass valve allows us to ditch grooves and reduce friction even more. 
 
All of this adds up to the lowest friction fork we have ever made, making this our most responsive fork ever.
