I'm about to give up on this Command Post and get something else.
It returns very fast with tonnes of force. It comes up so fast that it raises the saddle height. This is what the big problem is. The saddle height then is in the wrong position and it then makes my knees and legs hurt.
The seat post clamp is tightened at 5 NM.
I have put Carbon friction paste on the dropper post.
I have set the pressure to the recommended setting (15 to 20 PSI)
It still continues to raise the saddle height.
What makes the problem worse is when water gets onto the post. It doesn't have to be raining to cause this. Just riding where there is water on the ground (even with a rear Mud hugger!). For some reason when the Post gets wet it returns much quicker, coming up with a bang and causing the seat height to raise.
Lowering the pressure to < 10 psi just makes the post fail to return to its proper height a lot of the time.
Has anyone managed to solve this problem ?
I have searched the Web thoroughly for solutions about this and it appears that no one else has posted this problem! So this is my last attempt to solve this before giving up on the Command Post completely and getting something else.
It has had this problem from the start. However the return speed is more unpredictable in wet conditions than dry, which is why its become particularly problematic now.
All I can do at the moment is persevere with it and sit just above the post when returning it to prevent it returning too quick. But this does not make it a pleasure to use which it should be.
Spesh posts are designed to return at speed, Spesh say you are meant to control the return with your arse, your not meant to let it shoot up with no weight on it
There is not much else you can do apart from lowering the pressure, try between 10-15psi
Only other option is to sell it on and buy something else
Do the clamp up a bit tighter.
It's more mechanically sympathetic to control the rise with your backside but it shouldn't be essential.
If it's getting faster when it gets wet it sounds like it needs a service! Water is probably lubricating the seal and allowing it to move more freely and the seal isn't doing its job of keeping the crud out.
If you just let a command post rise in an uncontrolled fashion you'll end up knackering the brass keys and keyways. To raise the post, press the remote and stand up. Its really not difficult to do.
I have one as my first dropper and i got used to it in no time.
Sure its no reverb, but they are pretty reliable virtually impossible to break (unless you're an oaf) and are easily serviced at home.
I have one of these - I test the rebound with the pump still on - it's a very fine line between supersonic and too slow. But I usually cushion it with my arse or my inner thigh - it seems quite intuitive after a while.
But it sounds like yours needs lubrication. Give it a service and see if it'll rise on its own with lower pressure.

I must be an oaf then. Mine has been back to Spesh twice, once repaired and then second time replaced. Just stopped returning.

This is okay for normal riding. But for something like Cragg Quarry where the post needs to come up and down every few seconds! (the trail goes up and down constantly with no break)
It's a pain having to try and cushion it with your arse or inner thigh in this situation.. Often its a brief downhill then straight into a short steep techy climb where I'm trying to get the seat back up.
I'll have to ask local bike mechanic to service it. It already had a basic service recently but I doubt the seals have ever been replaced yet and it's put some miles in.
I've said this many times but I love the design of the command post, very simple - no hydraulics, just a simple air spring. Yes you're meant to control the rebound with your arse but I've never found this to be a problem, even at cragg.
