Hi! On my friends bike, the shock makes hisses and its easy to compress in the first 20-25% of travel as i described in the title
This is the position where i feel like the negative air chamber gets the pressure equalized, but after equalizing maybe the shock does something which it shouldnt? That results in an interesting feeling
Its firm at first and then after some pressure the shock compresses to 20-25% and then gets the “natural” feel which i think a shock should have (good rebound, compression behavior like on my bike and any other bike i tested)
What do you think is the problem? Can this be solved with a seal kit or something more serious service needed? Is it even servicable?
After the 20-25% the shock feels good and responsive
Ty!
First 20-25% of travel on RS monarch plus+ RC3 feels “weird”

Question – what’s his weight, the PSI in the shock,volume spacers? When was the shock last serviced?
If the bike has gone a while since a service it’s a good idea to do one. RS makes service kits and really good manuals, if you are halfway handy I’m sure you could do it yourself.
Needs a rebuild badly, that squishing noise means air is mixed with the oil so things just are not working right. Put the serial in here to find out the kits and rebuild process, if you’ve never done a full rebuild and bleed though, it is pretty tricky to do it right. https://trailhead.rockshox.com/en/product/search/serial
