specialized epic rear shock.

just looking for a bit of tech info please. my wife has a 2007 spec epic comp with the brain rear shock. on our last trip to glentress i noticed that the rebound in the rear shock was really slow even on its fastest setting. i have no other epic to compare it to so i was just wondering are they supposed to be slower than other fox dhx etc or do i need to get it looked at. any help greatly appreciated. mick.
There was a major problem with those shocks. Just bring it back to your specialized dealer and it should be swapped out no questions. last year epic upped their warranty to five years on inhouse suspension.
