Had a HiLo fusion dropper seatpost for a couple of years (it's out of warrenty). Never been very impressed with it - compared with a reverb - but it's OK. However, despite a recent service, it's now got a significant sideways rotation, drops half an inch when you sit on it, and appears to be leaking oil.

Is it worth getting it serviced again (new seals etc) or should I just write it off as a bad job and get a better post (27.2 being the issue).

I just saw on Stif cycles the KS Crux which is available in 27.2 and 100mm drop for £170..
i'd buy that over a repair that may cost close to that.

Thanks for the suggestion, but that appears to be stealth routed only, which I don't think is an option for me (unless I get the drill out!)

I just got an overpriced seal kit for my Hilo ~£25 plus some fork oil ~£5 sorted the thing for £30 in parts plus a couple of hours faffing in the garage...

Vs spunking £170... good VFM?

Key word cookeaa: 'may'. I have no idea how much an xfusion costs to service so just offered up a suitable cheap new one.

Ignoring the fact that if you happen to get things wrong, they can explode oil all over your face, they are fairly easy to work on and there's even a good video on X-Fusions website. The collar can be a bit of a pig to unwind with a strap wrench. I used 5wt oil in my Hilo SL to speed up the rebound a bit, and also internally adjusted the plunger so it allows oil to pass through faster when opened. Sounds like the OP's one just needs seals and keys, which are all in the one kit.

Any tips on how to get the collar off? Mine won't budge.

Wrapped a tube round the shaft and the top seal and used a vice and molegrps (still managed to mark the topseal) go easy on the force used on the vice.

Let the air out, clamp the post back in the frame, wrap the collar in an old inner tube and then use grips or if you can find one, one of those pipe strap things with a handle... The outside of the collar on mine is marked but it still works fine, for reassembly, it only needs to be as tight as you can get it by hand...

There used to be a really handy pdf for service instructions available online, but it seems to have gone. I might have saved a copy elsewhere but I can't find one right now...
