Afternoon All,
I have a set of 2008 Rebas that I have had since new and perform wonderfully.
I have the dual air system set up as per the RS manual for my weight etc.
One question though, if I add too much negative air pressure (i.e. more than the positive) it sucks in the stantions and reduces travel. Is this usual?
I guess its not an intentional design outcome of the fork?
[i]Is this usual?[/i]
Yes. Run my Revs with about equal +ve and -ve but still lose a bit of travel. Feel a bit harsh if I run the +ve higher than the -ve though
Yes, completely normal.
That is reassuring!
Its handy for reducing travel when needed - seemingly at no expense of performance 😕
I was a little confused when my stanchions started disappearing.. Then I remembered the sage advice.. Only set the +ve with the -ve completely empty, and then set the -ve.
Lo and behold, the rest of my stanchions re-appeared!
That's interesting Bikewhisperer, i've thought the travel on my missus Rebas looked a little short for awhile, this could well be why 💡

Just re-pressurized mine doing +ve first and all is good - full travel and dare I say it slightly better action 😳
Yes.. negative pressure works against the main spring. It's there to give a little boost to get the fork moving against the friction of the seals.
As well as setting + first, I find that setting the - with the bike upside down gives a more accurate Reading as you don't have the weight of the bike adding to the negative pressure ( this may work with + too but I only had the issues with the -)
nuke - same here
