Have you undone the collar and cycles the post up and down several times, usually gets mine behaving again.
Having said that though mine has just come back from 2pure due to oil contamination which amongst other problems was causing some spongy-ness. Had trouble getting a response from them via email, so rang in the end and everything was great from then on.
I’m sure this has been covered, but I can’t find it.
Joplins been fine for about a year, apart from the vast quantities of mud that it likes to swallow. However, it is now spongy at the top and bottom of it’s travel, no answer from 2pure and I’m off to Switchbacks in Spain on Saturday. Anybody had the problem and cured it?
I’ve worked through all the trouble shooting instructions to no avail.
If it’s spongy at the top (i.e. it moves down a bit without pressing the lever) it normally means there isn’t enough oil in it.
You’ll need to top up the oil and air to the correct levels (which will depend on whether it’s a 3 or a 4).
The manual / troubleshooting doesn’t go into this sort of stuff – it doesn’t even explain about the air pressure and how to set it (this is something I have to do on mine every few weeks when it starts to not want to spring back up).
