Ancillotti can call it whatever they like, the shock is compressed from both ends (one mounted to the frame, one to the push linkage). A true pull shock design works by mounting one of the shock's spring carriers to the frame via a trunnion mount and pulls the shock body through the static mount via the shock shaft.
ok i know that you mean , Ancillotti has called pullshok because the shock is pulled by linkage and not directly pushed ....is a simply monopivot with linkage......like to my Foes 2.1
i have also a yeti dh4 , that will posted here in few days ( i like call it extreme vpp )
