Going back to this, if you have a very basic shock then i think its worth it.
HOWEVER!! Also I find that a basic shock v a pushed one on normal UK riding conditions and I doubt you will notice much of a difference.
Now if you are doing an hour plus descent on rocky and varying terrain where the shock works hard and gets VERY warm (which affects damping etc..) then there is a huge difference.
My friend has Lapierre spicy 516 with the float RP23 shock, I have a Spicy with a pushed float R.
I hardly notice much difference, the rp23 climbs better, but obviously there is more slow speed compression damping….and you have to remember to flick the lever.
On the rock gardens I find the pushed one a bit more compliant… but only just.
Basically if I had an RP23 I wouldnt bother having it pushed but maybe ask Mojo to do some custom tuning whilst servicing for an extra £30 quid!!!
