IP-036 shock pressure (Rockshox Monarch RT3)

[DandyAndy]

Hi Guys,
what pressure everyone is running with your shocks on 036 Frame?

Some background story:
I put brand new Rockshox Monarch RT3 2016 on my new 036 build and at 200psi was still having ~60% sag (I'm ~85kg heavy). Being a recent convert to Rockshox from DT Swiss (which had burnt on me), I assumed that shock is a lemon and sent it back for a warranty. I am used to run 165mm DT Swiss at 80-100psi and it still was way too hard on my old bike. After repair it got better - at 200psi I'm having ~30% sag, however during the ride it sags further, (very much like that burned DT Swiss) and hangs on ~60-70%.
Now, I also have got a 2nd Rockshox Monarch RT3 2015 for my old bike. It's also brand new, never ridden so far.  So I put it on 036's instead and WTF!? I need 265psi to reach 30% sag.

So, do our frames naturally need such high pressures for the rear? Or is it just my "mega-luck" to get 2 lemons in a row?

There is an older thread here which is suggestive that this might be the case. http://chinertown.com/index.php/topic,799.msg8705.html#msg8705 However it is not active anymore and people there are some monster riders and rather discuss things way above my knowledge. 

BTW for the Front suspension (Rockshox Reba RL 120mm 2015, used to run Manitou Minute 3 100-120mm which is way too stiff) the picture is in reverse - need much lower pressures than recommended to get any notable sag (less than 10%). I'm currently playing around 60-70psi. Will see if it starts to bottom out.

i have a 036 and weigh in at 100kg... i have a fox ctd shock and i have mine set at 275psi (300 is max)

so i am on the upper end of  the PSI..

but i do prefer a bit stiffer suspension setup.

I bought an H/H tune damper tune assembly to swap in to the retail Monarch. That's highg compression damping and high rebound damping. That provides the correct time for the rear pivot leverage on this frame so you'll run a much lower pressure and get correct performance from the shock.

Installation is same as doing a full service, so doable if youre mechanically inclined. Pricey for what it is, but makes all the difference in the world. I weigh 165. Been a couple of years since I did the research and buy, so that's all I can remember.

Hope this helps,
Geoff.
