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!
