20220616 / mkr : Because of a current customer experience :

  • All this springs are originals from Marzocchi Z1 only! Don’t wonder : I have about 30-40 Z1 in stock for Spares and Rebuilds.
  • As written above in the product text this product will be sent new or used. I have some very limited NEW ones to sell, but will keep the last examples as master parts for reproductions. So I sell this originals ones from Z1 and Z2, which I have sorted by diameter measurement.
  • The ‘NEW!’ on the main prodcut picture indicates a ‘new product in store’, not a ‘new spring set’ in all – a common shop product tag.
  • Also for your information: only the after market spring sets have been coloured completly, the others are standard black (⇒ picture). They standard black ones might have a little coloured mark on the top (picture included) or not. You can simply identify the sprongs type by measuring the wire diameter! Standard diameter for Z1 100mm travel is ⊘2,75mm, the red ones have ⊘3,20mm.
  • Also please understand : all this springs are not made out of stainless steel, like most of all springs! That means they become a little rusty on the surface in minutes, if you take them out of the oil bath, which is absolutly normal. They will be send to you un-cleaned in a 90um bag to keep some oil on the surface.
  • If you have any other expections or detail questions please ask before you buy, thanks!

Seals Assembling
When mounting the Oil Seals put crease between the inner lips of the seals before pushing the stanchions in!
Important : Use a suitable tool to press the Oil Seal verticaly in!! If you don’t do that, the metal skeleton will bend.

Seals ‘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) )

Knob / Dial Installation Instructions
Please glue the little screw of the dials with a little bit of middle hard screw glue. And use heat if you want to take it off than.

Sticker Instructions
Please use the sticker only in conditions >=20°C environment to make sure the glue will work and make the tubes oil- and grease-free using isopropanol etc.

“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,
