Marzocchi MXC or MX Comp with the x-heavy spring set should do it. Is your back shock holding up
alright?

Hmm... I'm 250lbs and, as opposed to my experiences with my other Marzocchi forks (a 99 Z2
Alloy, a 99 Z2 Atom Bomb and a 99 Z1 alloy - all equipped with the stiffest springs available
for them), my experience with Marzocchi MX Comp forks has been that the x-heavy springs are too
heavy for my tastes.
When I built up my custom Curtlo steel hardtail last summer, I ordered a MX Comp from Doug Curtiss
(the framebuilder) because he said he could get me one with x-heavy springs already installed in it
at a great OEM price ($185) direct from Marzocchi. But it looked like there was going to be a delay
in getting this fork until after the frame was ready because Marzocchi USA was out of stock on
2003's and waiting for 2004's. Since I had an MTB event coming up in which I wanted to use the new
bike, I bought a 2003 MX Comp from my favorite LBS because they were able to get me one in a couple
of days through Quality Bicycle Products at a price that beat a lot of mail order places ($216 US).
At the advice of the LBS owner, I held off on ordering heavier springs for it until I saw how the
stock springs performed for me. To my surprise, the stock springs actually felt pretty damn good.
There was none of the mushiness, excessive bottoming out and brake dive that I experienced with my
other Marzocchi forks when I rode them with stock springs.
When I did receive the MX Comp from Curtlo, the first thing I did was swap the heavier springs into
the fork that was on the bike. I was suprised to find out how much harsher it felt with the heavier
springs. A major difference in the 2004 fork is that is uses an air preload mechanism opposed to the
mechanical screw type pre-load adjuster on the 2003 model. One of the advantages of the air-preload
set-up is that it gives you a means to adjust the overall spring rate without having to actually
swap coil springs. Since the preload mechanism is dictated entirely by the top cap assembly and
these parts are easy to swap between my two forks, I've been easily able to play around with
different springs and preload setups with both forks on the same bike . The setup I ended up with is
the stock springs from the 2003 in the 2004 fork with the air pre-load. For most of my riding I use
no added pressure in the pre-load. The only time I may add air pressure is when I know the ride is
going to be a long one on relatively smooth stuff.
Based on this experience I'd recommend heavier guys just buy a stock 2004 MX Comp and see how it
works out before getting heavier springs - especially if you have to pay extra for them. All you
may need is a bit of pressure in the pre-load to give you extra spring stiffness when you need
or want it.
