Craig only offers a limited amount of springrates for his shocks(you can use Rimic springs though) and depending on the average leverage of you frame the weightlimit can vary a lot.Extrovert said:
so i suggest you ask craig about this one, and tell what frame you will be using with the shock.
the weght limit for the DHF Ti forks is 125-185lbs
for the dual damper versions its 145-250lbs
i don't know whether there is a weight limit for the MTN forks
The MTN can be set up quite stiff so it should be able to take a quite heavy rider I thinkUiUiUiUi said:
Hell yeah... the reservoir on those shocks is equal to the size of a coke can!!grimm said:have a look at Öhlins
Funky Monk said:
Yep....huge !!!
The rear shock (DHS) depends on the bike and especially on the lever ratio. If the bike has a very high lever ratio the springs might be too soft. What do you ride and what do you use of spring for the moment ?Extrovert said:
Well, - get a bike with a low lever ratio rear suspension and maybe go for the hardcore version of the DHF fork. Otherwise try to send a mail to Craig at Avalanche and he will know exactly.Extrovert said:
The Brooklyn Race Link is nice. It has a 3:1 lever ration (9" of travel to a 3" shock). Otherwise bikes that has a 3:1 or lower than that in lever ratio would be a good choise I think.Extrovert said:
Extrovert said:
Well...a low lever ratio and a linkage that ramps up progressively so you do not get the bottoming out problem that some linear and regressive systems had in the past. I think (but I do not know much about it) the VPP is nice too.
do you have some specific ideas of which frame you would like ?
Get an older Karpiel Disco.. it has the lowest leverage ratio evar!!!!!!!!!!!!!

Yes...that would be a bad idea.....
:angry: 
Extrovert said:
I do !! :devil: :devil: And I ride one
Extrovert said:
On the other hand I do not have to worry about how the CS is.....it does not exist
Well, - I like mine a lot. Not a racer, but nice for tough FR and drops stuff.
Don't get me startedseismic said:Yes...that would be a bad idea.....
I'm just stoked I finally have my Avy workin on the Disco.
DLo said:Don't get me started
Ups......
.....sorry.
Extrovert said:
Then just make sure you do not get a bike that is too light weight. Not nice if you have to change it every season or something like that
Hey wait! The amount of linkages does not affect the ratio!!!
If you are a heavy guy, you need a strong bike and a good shock
3:1 or lower is good. A 600 spring and a proper valved DHS will do the job.

Agree
So Espen you reckon a 600lb properly valved shock would be fine for a 17 1/2 stone guy (like me)?/
The reason I ask and what made me think into all this, was after reading a post on mtbr.. See below..
''I love the quality of the Avy Shocks and am actually the 1st person to put one on a Tomac 204. Craig gave me a good price in exchange for sending him pics on how I got it to fit, etc. Very cool guy.
Here's the problem for me.
The Avalanche shocks are great and are durable and seem like a godsend for a big guy like me (265 butt naked). BUT....you can't fit a spring on the shock that's big enough for a guy my size. Even with Ti its debatable. I have a ProPedal Vanilla RC on my Scream and its worked great. Not as smooth and "expensive" feeling as the Avy I had on my Tomac but Its properly sprung. I know I would not need to use a 1000 lb spring(thanx Pohl) like I do with the Fox. But still 700 is the highest you can go with Avy without using Ti and 800 is the highest with Ti and im not gonna spend THAT much to find out that im draggin the ground again. Sucks for me cuz I love quality, durable stuff.''
Any thoughts?

that guy is riding a Scream.Extrovert said:
this bike has +8" travel and only a 2.25" stroke shock.
really bad leverage ratio!
so THAT bike is nothing for you
Extrovert said:
Sorry for bugging in, - I think it still to a certain extent comes down to the lever ratio. I have had a bike that would be stiff as steel in the rear with just a 450lbs spring......so even though you are a big guy, - with a loe lever ratio I think it is possible to atleast get a spring from Avalanche that is stiff enough. It all comes down to the bike I think.
It all comes to the ratio. A 600 spring needs 600 pounds to move one inch down. A straightrate 3:1 frame needs 200 pounds to move one inch. This is without damping, weigh distribution etc.
Ofcource teory only, but gives you an indication.
It depends on what kind of frame you want, and what kind of riding you are doing.
You might want a 700 spring but, my suggest would be 6-700 and a on a 3:1 Raceframe.
And, I am no expert, just an entusiast.

Extrovert -- I think you're trying to over-simplify things. Basically the #1 thing you should look at is the leverage ratio of your bike. For example:
Cannondale Gemini DH -- 2.3:1 ratio, singlepivot. Good
Banshee Scream -- 3.6:1 ratio, 4-bar (multi pivot). Not as good.
The weight spring you need is ENTIRELY dependent on your leverage ratio. Because Avalanche springs are not available in super-high spring rates, you can't really use them on super-high leverage bikes (as you understand).
Don't blindly focus on info like number of pivots and 600lb springs, because depending on what frame you get, those two pieces of info may be completely unrelated to what you need.
