  • Home service Reverb with squish?

    Getting fed up with Reverbs now.

    My AXS has gone to Sram for investigation as to why it just stopped working.
    Now the Stealth on my HT has developed about 10 – 20mm of squish when sat on.

    Have tried the turn it upside down trick and sometimes it works for 10 minutes before squish comes back.

    Other web searches suggest it needs to go for a service – question is, can this service be done at home?
    I’ve got reasonable mechanical skills and tools etc, but don’t want to jettison something into space if it’s under pressure.

    Post is well over 2 yrs old so out of warranty.

    SRAM have a full service guide on their web page, its step by step and quite easy to do if a bit time consuming. Its usually quite obvious what is causing the issues when you dismantle it, usually a damaged seal. TF tuned sell seal kits.
    The only pressure in it is the air chamber, make sure you let the air out first.

    If you’ve had a Reverb which lasted 2 years without needing a service you’re doing well.
    Just buy another brand which is cheaper and more reliable

    From what I’ve read and watched on YouTube the squish can only be fixed by a full strip and rebuild.

    Have a watch through this and see if it’s something you would be comfortable doing:

    If not, this eBay seller will service them for 50 badgers (it’s £95 at TFT):

    Rebound Suspension we’re doing it for a similar price but they’re currently closed due to illness.

    Home service is easy enough, take a look at YouTube videos to see what it entails.  I think SRAM had a pretty good video I used.

    Some special tools make life easier but you can maybe manage without for example the IFP height tool you just need some way of pushing the IFP down the correct amount and the oil height has to be set at a specific level for which I used a syringe and pipe thing originally for motorcycle forks but had to squish the pipe a bit as it was too fat.  Crows foot wrenches so you can torque various bits but you may be happy to guesstimate that with a spanner

    But if you have some squish there is air somewhere it shouldn’t be.  I’m always a bit cautious dismantling anything like this, wear safety specs and don’t put my face in the line of fire.

    Oh, I also bought a special thingy for clamping the shaft.  Not easy to get around that without risking damage.  Frankly I love how totally rebuildable the Reverb is but when you add up the cost of servicing them it sadly makes a disposable cheapie look more sensible.

    If I ever think I’d spend insane money on an AXS Reverb the thought of ongoing inevitable service costs snap me straight back to reality

    There was a thread on this within the last 6 months or so. I put a link to a good tutorial.

    As above, the full rebuild is not particularly hard, but it takes a while and you can find yourself redoing large sections if you forget a piece / compress the post at the wrong moment. I did three posts in the same session; the first took over an hour, the last one took 10 minutes once I knew what I was doing. I’d say it’s pretty doable for people who like tinkering with suspension forks.

    You’ll need an IFP tool, some suspension grease and oils in addition to (mostly) standard tools and a vice. I’d also recommend replacing the IFP and its O-rings (the reason they develop squish is because those components are worn).

    That said, my current post was under warranty (and I had a spare), so I sent it back rather than doing it myself.

    You don’t really need any of the specialist tools, although I’m sure it makes things easier.

    Oh, I also bought a special thingy for clamping the shaft.

    I made one of these with a drill, a plane and some wood.

    Oil height tool – all you really need is some stiff tubing and a ruler.

    IFP tool – I used a ruler and the barrel from a (road) bike pump.

    You don’t need to take the post apart completely to de-squish it in most cases.

    The non stealth ones you only really needed to take them out of the bike to let the air out IIRC.

    Watch the videos through and note the state of the post at the point when you set the oil height. That’s how far you need to take it apart, set the oil height and reassemble. It might not work, but it probably will.

    I should probably note that it’s not a bad thing to do a full service, I just don’t think they need it as often as some posts need a bleed. As I’ve scratched the air shaft in a reverb even using the proper clamps, I reckon it’s worth avoiding a full service where possible.
