will a PD shock fit my 1988 bumble?

[Monty]

Hi,

In my quest for a replacement shock for the bumble, I have been offered a fairly low mileage Fournales shock from a 93 PD. Will this shock fit my bike, and is the Fournales a good prospect? Will I need to go and buy the special pump to adjust it? I know nothing about these.

Thanks for your ongoing help and understanding.

Yes, the Fournales will bolt straight on, PD is same frame etc as the 'basic' paralever..and yes you need their pump as well Plus if going offroad keep a metal bar the length of the two mounting points of the shock...then if the shock suddenly fails...you bolt this in it's place to get you home

So these shocks tend to fail more than a sprung one? I have searched on here and elsewhere online and I have not found a lot of reviews or information.

They are excellant shockers but if they do fail ( remember no spring ) then they collapse..so the bar is just a precaution in case you are in the middle of knowhere
Fournales also do a full reconditioning service as well.....it won't let you down

I had Fornales shocks on a couple of machines great shocks and as stated rebuild is no problem, you do have to get the air pressure correct thou
that will come after a week or two. The Fornales pump is about £39
go to a push bike shop same pumps £28 VERY high pressure pumps...
Oh! and you can get ( from Fornales ) a flexy hose ( remote valve )if the valve in hard to get at.

Thanks for the info. Would I need to tweak the pressure if going 2-up rather than solo, for example? It seems a bit of a faff if I have to change the pressure for each change in load on the bike, but maybe I am just not getting it yet. It does take a while for me to work stuff out.

Here's some info: http://www.fournales.fr/catalogue/2_Roues/MONOC_-_Aprilia_-_Beta_-_BMW_-_Buell_-_Cagiva_-_Ducati.htm my guess is that 20 bar is good for solo and dual.
