Hiya !

first i'm sorry if the question was answered many many many times ..
i' tried to search but the computer answered :Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 40004 bytes) in /data/data01/web/html/files/search.php on line 996:

and i did'nt find the things i would like to know in the other topics

Sorry :)

now the question :

i would like to offer my pack a ti spring for christmas :)
my weight is 85 kg => 180/190 lbs ....
and i've got a 500*2.25 spring on my pack

the sag is 40 % ...

what should i take for a firmer ride ?

a 550 ? 600 ? 650 ?

and what kind of ti spring would fit the shock ?

7.5*2 dhx 5. is so short that most of ti spring i tried were impossible to mount without compressing the spring

help me :)
please

ps: my talas 36 rc2 is gone ...
and i've got a pike 454 for the moment ....


and soon a van 36 rc2 ....:)

i hope that i found the right fork for me!

I think they have a ti spring made by answer that fits the dhx shocks

What brand Ti spring are you considering ?

The RCS Ti spring is both a poor fit on the 2" stroke DHX (requires too much compression), only saves about 2 ounces and hits the reservoir thus causing damage.

We tried 2 different RCS 550 Ti springs for the Pack's DHX and both were simply awful.

So ... it would be better getting a steel spring ?

That's up to you, but those RCS Ti springs are quite expensive for a slight weight savings.
I can't speak for the Answer springs.

Supposedly Answer does - check go-ride. I was looking for that elusive RCS spring for the Avy and called them. They said they had them to fit DHX, but that the answer spring would not fit Avy.

Hey Benni!

I am a 75 kilo rider and run a 600lbs spring at my Pack with a half turn of preload and achive 30% of sag.This is with 100psi in the boost chamber.
I would suggest to testride a 650lbs spring for your weight, maybe you can use the 600lbs spring,too.But that will depent at your riding style.For an more aggressive rider it would be better to use the stiffer spring, a 500lbs spring is definiatly to soft for your weight.
I know this because I had a 500lbs spring myself mounted at my Pack stock.
Here is a link to a correct working spring calculator.

RaD,
I'm your weight and run a 550 spring. I agree that 500 is too soft although I wouldn't want to run a 600 either. Darren from PUSH is 175 lbs (80kg) and also runs the 550. I'm at the lower end of the 550 spectrum and he's at the top end.

I also agree that Benni would likely be best with a 600 or 650 depending on preference & style.

Squeaky,I had tested a 550lbs and 600lbs several days back to back at my local trails,messured sag and did anything I was able to do with my limited capabilitys.
The 600lbs spring fitted my riding style the best, but I ride fairly aggressive and have to keep an eye to the bottom out control ;) .
Sadly the DHX proggression adjustment is not that usefull as I wish, for my personal feeling the spring rate is just right... :confused:
I can still fine tune it by adding/releasing some pressure from the boost valve (compression damping) for the needed application,this means a bit lower pressure for freeriding and goofing around and a bit more for trailriding/XC.
But I just came across this
link wich is actually discussed in a different Thread.
There it says that Fox allows a tolerance up to 15% in springrate.This tells me that my 600lbs spring,at least 600lbs is printed to it, could be a 550lbs or 540lbs or 570lbs or whatever spring in reality.Sadly I have no possibiltys to check the real spring rate,maybe this could be the cause why your spring is softer and mine appears to be harder?
At least the suspension feels right to me and bottoms out only 1-2 times during decents,so it works for me.
