Upper Air Plug for older 24mm Marzocchi’s (pre XC500)


This is about an aluminium upper plug for older 24mm stanchions, named assembly Art. No. 17 for all older Marzocchi forks. It includes the base air plug, the valve base, the valve and an O-Ring. This part is very rare!

This is the complete Upper Air Plug which integrates the older valve model (compare to the pictures). It includes a Schrader (automative) valve and an O-Ring (4).

This 24mm version is used in most of the older forks built before the XC400/XC500.

It will also fit in the Marzocchi Rear damper A0033

Break-in Period
“Some forks may require 5-10 hours of use before the fork fully breaks-in. After the bushings, seals, and other parts have matched to each other, the fork will move smoother. The tight tolerances make the fork last longer and work better.” (original text from Marzocchi Bomber Technical Information (2000) )

Hallo Marcus, 
die Gabel ist angekommen und ich bin begeistert! Vielen Dank auch für die zusätzlichen Dichtringe und die Gummibärchen!!!
Wie kann ich die Dämpfung etwas weicher einstellen und welche Funktion haben eigentlich die Einstellschrauben jeweils auf den Standrohren?
Beste Grüße,
