[Closed] gravity dropper routine maintenance

my gravity dropper is working well now at the moment and I want to keep it like that.

On the site it tells you how to service it but I'm wondering how much is actually necessary to keep it running smoothly.

What do you do to it on a regular/ 'per ride' basis?
I have taken to just cleaning it, lifting up the concertina rubber boot, cleaning the dirt off the seal, putting a bit of oil around the seal and activating it a few times, so the oil lubricates the internal cylinder, and putting the rubber boot back.

Should I be doing more?

Cheers

Less.

I used mine for a couple of years before doing anything with it.

im struggling with mine at the mo - it locks out fine in the up position, yet when it goes down, it takes a hit, or bump and its coming back up without even touching the remote ๐Ÿ™

any ideas folks?

i really wish i could have a reverb ๐Ÿ™

If it's a GD and it's rising on its own, then the magnetic bolt which holds it down isn't seating properly. I'd strip it, re-grease it and make sure it's lining up. Once you've had one apart, you'll see how it all works and it becomes pretty self-explanatory

The biggest issue I have with mine is the cable getting sticky. If you haven't already I suggest you have the cable coming out the front of the post as its a bit stupid putting it at the back where it gets spray off the wheel. As druidh says take it apart and you'll soon see how simple the whole thing is.

Had this problem with mine:

The cap at the top of the lower post can be turned to adjust this. Give it a try!

cheers folk!

ferrit - the top cap you mean?? ive tried that, i tried loosening it off, and tightening it up - but neither seemed to work....

it locks down for a period as though its normal, then say your descending, then hit a bump/rock it goes back up on its own ๐Ÿ™

actually quite dangerous and distracting last night ๐Ÿ™

is there a fine adjustment to it, ie, dont tighten it all the way, and dont loosen it all the way? i took the play out of it as per GD site, but it still did it?

Yep, I meant the Top Cap.

Bummer - ah well, worth a try!

Routine maintenance for my GD is to remove the whole top section and clean up with a rag/re-grease. Once a year new cables and shims.

If your GD is moving independant of input make sure the top cap is set just right. The best way to do this is from full loose wind down half a turn at a time until you can get the lowermost position locked. Before doing this apply a small amount of loctite to the threads. This will keep the GD in the correct position and allow perfect movement to all given positions. Also check your cables as they get rough over time and can prevent bolts locking into position.

cheers duir - ill give that a shot, doing from all the way unscrewed makes sense, ill give that a try and then loctite the thread slightly, as it does definitely move slightly if not overly tight ๐Ÿ™‚

its a bummer as it has been working flawlessly for a while, then i had to adjust something else and havent had it working right since ๐Ÿ™

Turbo is pretty different to the classic in some ways, the post design is more or less the same but the actuation's totally different, no magnets, just a big bolt on a spring. It's a cruder, less clever system but simpler and IMO better.

So. What you have, is the bolt not engaging right.

Strip it down, clean it all, check the cable especially as it's the most likely cause by [i]miles[/i]. Mine had a wee kink in it that caused this to happen. Also check the holes in teh post to make sure they're not filled with grease or damaged round the edges- people get carried away with grease on these, it can stop them working.

I'd start just by unscrewing the bolt mechanism from the post and checking it's moving freely and smoothly.

Northwind - spot on squire! it was the pin thing not retracting/engaging properly, give it all a good clean, and some lube/grease and its working back to normal......the spring inside the turbo bit (where it angles off the post) was completely rusty and hardly moving, hence the pin bit not moving....good clean, lube up and shazzam back to knocking my bawlls up into my throat...and the no more random popping back up ๐Ÿ™‚ cheers northwind!

northwind - help required again ๐Ÿ™

jesus i had the worst day today with this blooooody post ๐Ÿ™

about 16 miles into a 37 miles ride (in the middle of nowhere/no return...and low and behold, my bloody seatpost starts to drop on itself......

i thoughtttt noooo, at least if its locked in the up position, ill be comfortable for the remaining 20 miles....but ohhh no, the bloody thing wont stay up....i had a fiddle with it, and again it appeared that the pin was not going in far enough to lock it out whilst up...(considering id messed with it yesterday, and the only other thing i didnt do was change the cable inner and outer)...it appeared fine, and was certainly fine for the first 10 miles or so, including being dropper and going back up...suddenly it just flopped...

i then had to ride for the rest of the ride with the seat post it the max line limit just to try and get some height (which was incredibly painful on the next 2000ft of climbing ๐Ÿ™

so i got home absolutly furious with it, and i mean raging, id already told myself i was going to saw it in half when got home ๐Ÿ˜† and stick my trusty thomson back on....

anyways, changed the cable to xtr and sp41 outer....finally got the thing to engage, and now it appears back to working again (as it did last night too).....the only difference is, if i tighten the two screws on the Turbo bit which holds the pin in place, then the post wont engage....so i now have the 2 screws not tight at all, but just about holding the turbo bit in place??? if i tighten up it wont work...if i leave it like that as soon as i hit rocky stuff i think they will defintely come out?? any ideas? i am missing something obvious?

i locked the big main spring underneath the pin bit first, to obviously stop the spring from shooting up.....then added the seat post in, parallel with the hole on the GD post.....

im so pisssed off with it today, really i am, ive had nothing but bother for the last month with mine, i only had it in november too ๐Ÿ™

ended up spoiling what had started as a pretty awesome ride ๐Ÿ™ ending up looking like im riding some form of dirt jump/bmx size wise for the remaining miles ๐Ÿ™

why oh why didnt RS do the reverb in 27.2? ๐Ÿ™

I don't know what's going on with it only working with the screws not tightened, but assuming the rest's really clean and the spring's working properly, and no catches/burrs on the holes in the inner post, then have a fanny about with the adjuster. Past that point I don't have much to add though, sorry

yeah its very very very strange, i really do not understand at all...i suppose if i screw the 2 screws in all the way (tight), it pushes the pin even further in? which its then not coming back far enough to dislodge the post and let it sink back down to the lowest position?

honestly really annoyed with it now, i had 4 months no problems, now the last month, every ride something seems to go wrong, and not always the same thing....the last 3 rides ive have spend far far far far far much more time messing with it than, if i just had a QR and normal seatpost :(...

im seriously considering it i must admit.....

anyone after a GD turbo 4"? id be willing to swap it for a new hope eternity seatpost?

only applies if your sufficient in fixing and maintenance, as ive just about had enough of it with this ๐Ÿ™
