Mountain Biking - setting up marzocchi super t rcv

hi everyone, my son has just done a custom build iron horse yakuza ojiki, he has marzocchi super t rcv 2007 forks
please would somebody tell me how to set the forks up to his weight, he is about 8 1/2 stone, he'd like the forks very plush with quite quick rebound, he would like it setting up for dh
please help

please will someone reply because we are off riding this weekend and they need sorting, originaly they were set up for a 16stone rider

You could have found this, you know.

thanks m8, what sort of biking do you do
e.g. dh, freeride

hi that page oyu showed me didnt have how to set the forks to rider weight, do you know if so could you tell me

Dminor is a down hiller and free-rider...
looking at his sig would tell you.


Look at the owner manual for the fork... theres something called "setting sag or something along those lines."

Do you have lighter springs?

he got the forks off ebay so no manual and also i dont have any lighter springs but i will get the bike shop too sort it

I have a Marzocchi fork, so I've over looked the manual.
go to page 65, 66, 67.......
65-74 has everything you need for it.

Doesn't the Super T RCV have an air preload in addition to the spring in each leg (page 63)? On page 65 doesn't it tell and show a chart how to set the air pressure/sag per rider weight? Would you like me to fly there and read the manual to you?

Seriously, if you can't get it close for his weight with the springs you have and the air settings, you may have to go to a different weight of springs.

the air is really easy to set up.

since the fork is relatively low pressure, I used my frame pump (mini pump for pumping up tires) and just pumped slowly (it has a built in gauge)

Not a problem.

"

How to fi nd the best SAG
The best SAG for Cross-country forks is 15–20%, and for
Freeride forks is 25–30% .
In order to calculate the best SAG for your own fork, you will
need to make the following calculation:

SAG = T x S
T = total travel

S = suggested sinking percentage.
The best SAG is obtained by varying the spring preload
(spring fork legs) or by varying positive air pressure (air fork
legs)."

put a ziptie around the stancions. Have him sit on the bike, not bouncing and measure how far the fork compresses. (the ziptie will move up to show how far.)
adjust accordingly.
you will want a suggested 25-30% sag rate.

sorry i dont know that much about forks bu it has got 2 air valves on the top
thanks

hi i looked in the owners manual at the pages you told me but it says something about posotive air pressure, im not sure if is fork has that, there are two valves on the top but i think they are for setting spring preload via air, if there different could anyone tell me which is the different one and what it does
e.g. which is positive air and which is preload, but both the valves look the same so im not sure

looking at the manual...
theres a chart that lsits every single fork they make, and it has all the features, like positive air, preload, rebound, ect... it tell you what side of the fork it's on, and where its at.

the valves are going to look the same, they are both shrader valves.

On my fork, (MX Pro) both sides are positive air.

edit:
page 63:

Both the air valves are spring preload with air.....

and both legs have adjustments for RCV, which looking further up on the manual is: Rebound Compression valve.

these will most likely be on the lowers of the fork?

me and my son are going to try and adjust it tonight. i will tell you how it he gets on later tonight
