Once that's done, it drops fine, and extends fine, then drops again absolutely fine, until it's been extended fully for about half an hour, and the issue repeats itself.

    Any ideas? It's only a niggling small problem, but certainly one that wasn't there at the beginning of its time!
    What happens if you adjust remote to a slowest setting? If its getting worse bleeding of the cable should help.

    ^^^Yes. It's also possible to over-tighten the post clamp so it restricts movement of the post. Check the clamp torque. I believe the spec is 6.7 Nm (60 in-lb) max.
    Do the math.

    My reverb is much better after partial cleanup/regrease (was not able to remove lower cup, so no way to get into upper dust cover, need vice jaws thing for 9.5mm tube). No single "got stuck" situation on today ride.
    I guess I will get vice jaws and will do dropper cleanup/regrease from time to time as shown in the video below. Then it will be time to do "service kit" thing.

    That might be spec, but on my bike, anything over 3nm and it binds.
    Alcohol may lead nowhere, but it sure is the scenic route!

    ^^^ Yeah. It can be clamp dependent. Not saying this is your issues, but if a slot in the seatpost lines up with the slot in the clamp, it can really dig into the post. Arranging them so they don't line up can help. This is usually the default arrangement for use with carbon seatpost. Sometime they're 180 degrees apart but in some cases the seat tube may have two slots (Trek, for one) and the clamp slot is equidistant between the two.
    Do the math.

    it might be that you have an issue with the brass inserts since you wiggle your post before being able to put the post down. better make an appointment with a service or you can do it on your own with the right tools and instruction from sram via youtube.

    Question about the process to rebuild the Reverb stealth:

    Pulled it apart last night for the first time to reset the IFP, oil and all that because I was sagging. I had to make my own IFP oil height gauge using one of my remote bleed syringes and a piece of aquarium air hosing. With my Reverb, my height it supposed to be 186.5mm. Fine no problem. But what I found is I couldn't get the tubing far down enough in the shaft to get the full 186.5. I was off by 4 or 5mm. I double checked and this is because the diameter of the hosing is too wide to fit through the blue 'thing' that presses into the IFP tube. I'll have to source a slimmer tube. I reassembled anyway just because I was at my wit's end. At the end of the day, the post is solid and seems to work fine....not trail tested yet.

    So how critical is that oil height? SRAM makes it look like it has to be on the money exactly.

    Ive got a proper oil height gauge and it only ever picks up small dregs of oil. The first few times I actually poured some oil in so the gauge had something to suck up but found it wasn't necessary. I don't think it needs to be that accurate. The best test is a working post.

    Perfect good to know. I didn't get a chance to try it out on the trail but the post seems to working fine. Thanks.
