Help!!!
Has anyone any Ideas about how to set up a Marzocchi 55 ATA Fork?
The instruction manual is next to useless and I cant find anything on the web.
In the instructions it says there are 2 Schraeder valves, but I can only find the one at the bottom of the right leg, where's the other?
My weight is 65kg
Any Ideas please!

I don't have a 55 but on other Marzocchi air forks, the positive air spring is normally at the top of the spring cartridge leg (ATA leg in your case). Is there a central cap that unscrews or a hole in the adjuster that lines up with a valve underneath.
The one on the bottom of the leg controls the spring ramp up so you can steepen the spring curve if you're bottoming it out, or slacken the curve off if you find your sag is right but you only get partial travel when riding.
Good luck!"Internet Forums - an amazing world where outright falsehoods become cyber-facts with a few witty key taps and a carefully placed emoticon."0 -
I found this topic because I too am trying to work out how to set these babies up properly. Please post up if you find anything useful.
Anyway, I can help with your question: on the top of the right leg is the ATA adjuster, this simply pulls off. You don't need to (can't) unscrew it and it's quite stiff.
Underneath is the schrader valve for adjusting both the positive and negative air chambers simultaneously. The valve you've found at the bottom is for tuning how the fork progresses through the end of its travel, ie bottoms out.
The problem I'm having is that the pressures suggested by marzocchi seem to make my fork stupidly stiff, and I'm also a bit unsure how the TST micro (gold) works in conjunction with the slider (red). Anyone?<font color="blue"><hr noshade size="1"><hr noshade size="1"></font id="blue">

well ive got some old marzocchi air forks (z150 from 05) and the pressure suggested by marzocchi is insanely stiff so just let some air out and experiment.Specialized Big hit (custom build, nearly done!)0

psyickphuk I think the gold dial is just to fine tune the compression in conjunction to the red TST dial which is a rapid compression adjuster or lockout.
Thanks for revealing the location of the second Schrader valve that one had me stumped, Marzocchi instructions are really bad!0 -
yer just experiment. diferent fork i know but i onyl run 38psi in my 36's wehreas it recommends about 60 ish in the manual for my weight. adjust it to what suits you.I said hit the brakes not the tree!!
