I've had a Oneup components dropper post for about 3 months and in the last week it won't return to full extension.
I've done a full service as per the Oneup components website.
Has anyone else had this happen to them? If so, what was the solution?

Many thanks

Dom

I had the same thing happen after about three months. I found that it only had about 150 psi when they recommend 250 - 300 psi. I bumped it up to 275 and it's back in action. I'm going to keep an eye on it to see if it loses any pressure going forward. Good luck!

I had the same problem, about 3 months in. Checked the pressure and it was at around 130 psi. Put 250 in it and it has been fine ever since.

Thanks for the replies, I should have said I've pumped it up already.
I'll check it again.

Hi I have a warranty replacement OneUp Dropper 170mm, working perfectly with a WolfTooth Remote.
A few months ago it stopped fully returning. I tried everything below, and found the white bush under the collar was too tight. Popped it up, removed it from the shaft and had full return. Lightly sanded it inside and out until it went in smooth, regreased and refit. Hasn't happened since.

-250-300 psi - done to 300?

-Top cap seal dry/dirty - Open it up, test, clean/lightly grease as needed, test.

-White bush under cap too tight - remove, test, sand thinner if too tight.
.
-Seat post clamp bolts too tight - my frame spec is 5nm, first post would not work over 3nm. Current post works ok at 5nm.

-Isolate post / lever from frame

-Isolate actuator from lever - remove cable, ferrule, test manually.
[-Don't let the o-ring and metal part drop down your cable into frame, you'll need to feed the housing up and nearly out to retrieve them.]

-Pull it apart for a service/ inspection - done - was the upper white bush tight?? That is all I found wrong with mine.

Good luck

Same issue after a month of owning, even when properly pressurized, proper cable tension and seat-post collar torque. I had them send me a warranty replacement, I am not opening up a month old post to do a service or sanding anything thats crazy.

I had the same with mine and it was the cable routing. Because the outer moves, not the inner, it can be an issue if the routing is tight. Apparently lots of SC owners have had problems due to this. Mine is the V1 by the way.

Thanks for the replies!
The post has started working properly again strangely. That said, it does creak a lot!
