Dhx
Can anyone help me with the DHX 5.0/AIR?
The boost valve, is this the same as compression dampening? (As in high Boost valve pressure [bvp] (150psi) is like running lots of high speed compression dampening)
As far as I can work out you can treat the propedal as a low speed setting and use the BVP to control high speed, but the bottom out effects this in the rate at which the high speed dampening ramps ... except the bvp seems to effect everything including low speed, since as far as I can tell it pressurises the oil (actually it seems to reduce the pressure difference of the oil flowing through the compression circuit. Hence slowing the oil making the shock slower to react, sort of making the shock stiffer, but without changing the spring-rate.)
So as far as I can work out, there is an ideal spring-rate from which you shouldn't deviate from (main chamber pressure for the air/correct coil and preload for the 5) giving 25% sag (depending on bike/geometry) then you should leave it well alone and only change the BVP and bottom-out and propedal, assuming you find the right rebound setting for the spring-rate.
So if you want a plush day, or your only going to ride little terrain but you want to use all of your travel back the BVP (75-80) off, and the bottom out (2nd line). But if you are going big crank up the BVP (142) and in (all the way) with the bottom-out.
Propedal depends on BVP for me, if I am running enough (120+) BVP I find I don't need any propedal at all.
Now my questions, has anyone found them to be useable with the bottom out all the way out?
Des anyone use a different combo of settings to me? (High BVP bottom-out out/bottom-out in BVP low)
Can anyone notice the effect of propedal at all after 120psi on the BVP?
Oh and is the unit noisy on the compression stroke? (Not the rebound)
I am trying to workout if my shock is fucked (I operated it with the BVP at 0psi, not such a good idea on the face of it)
