The advice so far is good. The shock will require a slightly different setup for each suspension type. When I did mine, I started off with 75% of my bodyweight as a baseline. 2/3 would be absolutely fine also – it’s up to you, as you will be adjusting from the baseline anyhow.
To be clear – take your weight in lbs and set the pressure to 75% of that in both the black and the red chambers and fiddle from there.
I am 200lbs so I put 150psi in the SPV (red) chamber to start with. I put the same amount in the main (black) chamber.
You are 56kg (~133lbs), so start of with 90-95psi.
With this starting pressure, measure the sag using the o-ring on the piston or use a zip tie as a substitute. You want about 25% or so of the overall travel.
I mucked around 20-30psi here and there and after 10 minutes worrying my neighbours riding round in circles in my garden and jumping the bike off the patio, ended up with about 160psi in the main chamber and can’t remember what in the SPV one – something like 155 I think.
Have a muck around from those settings and you’ll have it bob-on in no time. 😉
