hello everyone,

i was looking at getting one of those statos ID cartridges for my new marz z.1 i have on the way but i was wondering if there any good i mean they sound good reading the discritiption on the stratos website but of course they want it to sound good so i'm wondering if any of you guys know anything about it? are they worth it? do they perform good? and other stuff like that

from stratosusa.com:
ID CARTRIDGE WITH INERTIA VALVE DESIGN SHIMMED FOR YOUR RIDING STYLE....

I've spoke with mike the owner and he said the inertia valve is like platform damping for your fork (i.e. manitou's SPV) but can tell the difference between rider input on the bike and terrain forces.....That is, pedal bob/fork dive it will resist, but still be responsive to terrain/bumps, under acceleration.

As long as you learn to pedal effectively without mashing down on the pedals and keep you shoulders still, I think Platform systems for a fork aren't necessary, at least for Downhill.

Others may feel different for XC applications....where you pedal .... waaay too much.

Go to www.mtbr.com to the "let's talk about shocks" forum; http://forums.mtbr.com/showthread.php?t=51397
There are a few threads there about this subject, including input from people who actually have the cartridge in their fork. I am a couple days away from recieving one for my super T.
Bacardi, If the id does what I'm told it will, it does have a place in dh forks. Eliminating some brake dive, and having a higher ride height when pointed downhill are two great benefits for a dh rider.
Besides using the brass weighted inertia valve like fox does, each cartridge is shimmed for a specific purpose with cup shaped shims. The fork is never locked out like the fox 100x fork is, and is supposed to react much faster than the fox.
I'll be able to give a more first person report in a week or so.

Here is an excerpt from one of the threads, from the guy who licensed the technology to stratos;
If you havn't riden an ID I can see why you be concerned. This is exactly the kind of question I asked myself before I designed and made my first inertia shock. What I found is that you can only theorize so much and you have to just build it, test it and then figure it out. The results are hard to explain and I'll do my best. The Stratos ID chassis circuit allows the bike to sag so that the wheel can extend (minimize tire force variation) and not alter the frame geometry. As you know when your going downhill the inertia valve is covering the compliance holes which means that the oil can only go through the chassis circuit. The chassis circuit is a shim stack that is tuned to blow off above the force needed to address pedaling inputs. When the inertia valve opens the oil is then metered by ANOTHER shim stack as opposed to just a BIG hole ie: terralogic. The compliance circuit and the way it's metered is critical to the way the bike feels over the bumps. What happens when you go downhill and the inertia valve opens, the compliance shim stack gives some low velocity resistance. The overall downhill bump response is that the chassis rises even though you used some travel, then the wheel goes over the other side of the bump and the wheel extends , the dynamic ride height stays about the same. The feeling is that you have the security of a better angle of attack and plushness at the same time. It sounds to good be true, but I'm sure other riders will speak up. These inertia valve benifits only apply if the valve responds within milliseconds and your not using a big hole for a compliance circuit. If your using an inertia valve fork that has a hydraulic delay (reset) feature then all bets are off. OT: I have not been able to respond to many questions for a few reasons. 1) time, I'm in the middle of setting up an new CNC R+D shop to address the needs in off road racing, and an affordable twin tube shock for car and truck aftermarket, etc. 2), I've been asked by my licensee to knock off giving their competitors information on MTBR.com (I can see their point). Some questions I can't resist .3) I'd rather see people without a vested interest respond.4) I've been traveling. I can't tell you how good it is to see this technological breakthrough get recognized and enjoyed. Hope this helps, Don R.

From that thread on mtbr it's really put me off getting an ID and i'm now 100% keen on the Mojo kit for my Boxxers.
