No change to the damping curve at all. In rebuilding a shock from each year back to back, the only difference I found was that the outside bleed port now has a small allen head bolt instead of the old Phillips head bolt. Shim stacks and porting and volumes are all completely the same.
The only significant change was after the '06 shock where they had a heavier shaft made of...steel? Can't remember, but it was silver and heavier.
roco 2008 has a smaller ai chamber and also a new range of pressure 170 to 210. the 2007 has 180 to 220psi. i dont know if its meanin somethin...
But its true that roco has a better small bump sensivity than dhx 5.0?
I heard it is enough to let air out, remove the schrader valve and you can actually move the IPF by turning it in or out. I'd like to make my roco more progressive but never had enough courage to do the trick myself. Is it truly that easy? Or you have to add/remove oil via bleed screw to compensate for changed volume?
