So I have a 2017 Specialized Stumpjumper Comp. The only problem I'm having is with the lockout on the Monarch RT Autosag shock that comes stock on the bike. There is air in the shock and it is set up correctly for my body weight with the Specialized Autosag feature. The shock performs great riding Enduro and gnarlier single track. The problem comes when I lockout the shock for a climb. When the lockout switch is fully engaged, it feels like the stiffness doesn't change at all. I don't think there could be anything wrong with the shock considering it is only one year old and it hasn't experienced anything outside of normal use. I'm wondering what I can do to change/fix this, I know it will never lockout completely because it can cause damage to the shock but I feel like when I lock it out it should be significantly stiffer. I've also heard one of my riding buddies mention the lockout max is only at like 215 psi or something like that? Not sure if than means anything or is true? If you could help me out at all it would be much appreciated. Salute

Forgot to mention before as well, I work at a Specialized dealer and I checked out some of the other bikes with the same shock as mine on them, all of them perform exactly like mine. I'm assuming this is a tune thing but I'm not sure how to make it better if it's even possible.

There should be a label on the air can with the threshold and damper tunes.
Has it been the same since you got the bike, or recently gotten softer?
If it really doesn't feel any firmer in the T setting, take it to the LBS to see if it's a warranty issue. I think SRAM stuff has a 2-year warranty.

It has been the same since I got the bike. The label reads M then under an unlocked symbol- L and under a locked symbol- 219.

Hi all, I just took delivery of my Reign 2. My Monarch RT rear shock also seems not right to me. I'm 13st+ and need to run 320psi for 30% sag and lockout only reduces it to 20% sag. I have not ridden it yet due to this as I am sure this can't be right.
Do I need to take it back to where I bought it?

I had a similar issue on my enduro where my shocker would stick halfway down in the cycle maybe.. 45% and none of the features worked, turned out it just required servicing i managed to get in under warranty.Jailbreak Jailbreak

SKIGAN14 did you get this sorted out? I've just got my hands on a new 2017 stumpy expert 29er and i'm experiencing the same problem.

I haven't. Let me know if you find anything out!

Can be a few things. Your IFP pressure could be too low, resulting in the compression assembly not closing fully. Could be the compression valving is actually broke as well. This shock has seen its fair share of issues. I would do a complete overhaul to asses what is happening.

Hey guys I have the same shock but on a 2014 Norco Sight. What I've discovered is that my Monarch RT shock has something called "threshold" not lockout. The "T" in Monarch RT stands for threshold, which does not lock out the rear suspension like a Monarch RL ("L" standing for lockout).
I've also discovered that for me it does work (barely) out on the trail. It makes a near negligible difference and worse yet it will take a minute or two after flipping the lever for the threshold to engage and become noticeable. I'll flip it to threshold when I know a long climb is coming. Once I'm at the top I'll bounce while sitting and turn the lever to open and there is a difference immediately apparent. The shock will feel supple once I put it in open mode. Flipping it back to threshold while still bouncing on my seat does not bring back the firmness I felt in the shock just 2 seconds prior when I flipped the lever from threshold to open.
Its weird.

UPDATE:
So I took my bike to the shop today and checked the IFP pressure. It read 100psi on the shock pump, and referencing the RockShox PDF manual that was 200 psi lower than the recommended 300! If you have a Monarch RL its up to 500psi in the IFP chamber. We pumped it up to 300 psi as recommended (you need an adapter for your shock pump to do this by the way) and now my threshold kicks in quite noticeably after 4 quick cycles, or bounces. This has fixed the issue for me. Beer Big Grin
Also, I didn't have to adjust my psi for 25% sag level afterwards.

I just got it back from service and it's doing the same thing. I will check the IFP pressure when I get home. Hope thats the solution tup

This is a common issue with these shocks. Some say its a "characteristic" of the design. Rob at Fluid Function has some crafty fixes for these. I suggest sending your shock to him.

How do you access/measure the IFP pressure?

The port is at the bottom of the shock near where the rocker pin would go through. You have to use a valve core removal tool to open the port (it's just a cover, not a valve) and that will expose the IFP valve. You take your shock pump and a special adapter and thread them into the valve. The shock pump gauge will read the IFP pressure and you would treat it just as you would the main air chamber on any air shock.

Sorry to necro this thread. but I'm having the same issue. my question is do I need to remove the pressure from the main chamber before adding pressure to the IFP chamber?
