Most more expensive posts seem to be totally rebuildable, but the top seal collar and cartridge are the only obvious parts the user can access on a giant.

I got about 100 hours out of my first Giant post before they warrantied it without fuss (and then a carbon frame a week after that came back). I’m guessing posts are still quite an immature product in the grand scheme of things and will start to get better in the next few generations.


There is a clear divide between posts which can have the innards serviced and posts which can only have major parts replaced (i.e. crimped shut gas struts inside).
Then there is the second divide for whether those parts are available.
Then a third for whether they're worth fixing even if they are servicable. There have been some absolute shockers sent to market in recent years.

Price is not an indicator of either and the market is that full that it's hard to keep up with all the different options.

On giant posts there are two horizontal grub screws in the top that retain the top of the gas strut. Remove the collar and those and there's not much left.

There's the bushing the inner post slides on. I can't see how to get to it.

FWIW. I bought a Funn UpDown from T7 for $236 (on sale from $359) and the cartridge seized after 10 months. Brand new one turned up a week later no questions asked. Really good service.

Then I sold it and bought a new bike :satan:

That's what I paid for the giant, and after one cartridge warranty it's been sweet.
I just like to stay on top of routine maintenance, and feel thwarted.

10 months being used in Wellie should be covered by the CGA.

I'm Wellie based very abusive of dropper posts (originally the Gravity Dropper, then Reverb and now KS Lev) - ride in the rain and mud etc.

Suffered from the early quality probs with the Reverb and that cost a bomb once out of warranty.

The Lev (for me...) has been by far the best. It does need waterproof grease under the top seal and a regular strip down clean to stop water-based corrosion.

I totally can't believe how the Lev has been so good for so long. Remarkable that it is still smooth with no slop.

Undo the lower actuator cap, remove the 2x grub screws in there (2mm hex key). Unscrew the collar and everything slides out the top.

You have to pull pretty hard to get the bushing to come out though, a bit like a slide hammer. Watch the plastic bits at the bottom dont fall off and disappear.

I had my Reverb rebuilt. I'd had it serviced and was warned that it needed an overhaul. Worked faultlessly until it didn't. Anyway, long story short, it needed a new piston. The distributor in NZ didn't have any, so the shop gave me the part number so I could order it online. I think it came from Germany in the end. I think all up it was nearly $250-300 to rebuild. I hope it lasts another four years!

the PRO droppers are similar to a KS, just replace the cartridge if when it expires
PRO is shimano's finishing kit brand so spares are available, not seen one yet but have been considering one for an upcoming build :paranoid:

How much faster was it after that? Depending on the brand and spec the oil you put in is 2-3 times thinner than the stock stuff.
