Marzocchi Bomber Z3 light - New Spings

[Paul]

Hi,

I have a set of Marzocchi Bomber Z3 light forks (Not much used over
last few years) from either 1998 or 1999, and I have a number of
queries which I hope someone might be able to help me with.

1. I am quite light and my sag is only about 18%, which I think is a
little low. Am I right in saying I probably need soft springs to
increase this sag up to 25%? If so does anyone know what the spring
rating was when the forks were new i.e. soft, medium, hard or extra
hard?

2. The adjustment on the top of the forks to increase or decrease seem
to make very little difference, is this normal?

3. All the documentation on this fork suggest the travel is 65mm
however my forks seem to be 80mm (if I am measuring from the right
point)

4. Chain reaction for 80mm forks only have med rated springs and above.
Does anyone know where I can get soft springs (UK) for these forks?

Thanks for your help in advance.

Paul

If you're preload adjusters are all the way out (anti-clockwise) and you
can't get the sag you need you'll need the softer springs, I believe they
came with medium as stock. I don't know if Marz is still supporting their
older models. If you were in the states I'd say check with QBP or BTI to
see if they had compatible springs in stock for your model fork. Check your
LBS for whatever parts catalog they have.
