Considering one for the 36 when I bump the travel up to 170mm.
Thoughts?
Gimmickry, or the real deal?

It works pretty well for the end stroke fine tuning. I've had it both on Stage (air) and Ribbon (coil), has about the same effect on both.Got one in my Ribbon coil. No idea if it works or not. I've never bottomed the fork out... so maybe?
I think it's totally different in the coil, I'm guessing adjusting something in the damper, vs the cartridge for air forks which changes volume.Got one in my Ribbon coil. No idea if it works or not. I've never bottomed the fork out... so maybe?
It is the same thing - it limits speed with which air gets displaced to the lowers during high speed compression.I think it's totally different in the coil, I'm guessing adjusting something in the damper, vs the cartridge for air forks which changes volume.
Nope - has no impact on anything other than teh end of the stroke, from what I understand.Does it help with small bump sensitivity in the very beginning of the shock stroke?
Having a piston and seal with the right dimensions is more likely to help for small bump compliance. I don't know which generation is your 36 but the 2015 to 17 ones were randomly bad... I don't know if the newer generations are better.Does it help with small bump sensitivity in the very beginning of the shock stroke?
Kinda - indirectly. It prevents bottoming out in a reasonably setup fork so you don't have to dial as much HSC as you'd have to without the cartridge. In other words, if you compared two forks with the same resistance to bottoming out - one with the ramp up cartridge, one without, the one with will have less compression damping and therefore better small bump sensitivity.Does it help with small bump sensitivity in the very beginning of the shock stroke?
It is the same thing - it limits speed with which air gets displaced to the lowers during high speed compression.
It's a speed sensitive valve that controls air passing between two chambers. When air starts moving fast enough it chokes on the valve and you get the effect of a smaller chamber. The adjuster changes pre-load on the valve.
I should have mentioned "in the coil forks" in my line above. In coil forks, it basically turns the lowers into a secondary air spring that has real impact in fast compression events.
It's an '18, which is supposedly much betterer...Having a piston and seal with the right dimensions is more likely to help for small bump compliance. I don't know which generation is your 36 but the 2015 to 17 ones were randomly bad... I don't know if the newer generations are better.
From MRP's website:I bought it specifically for the claims of better small bump performance rather than bottom out
50 psi for your weight seems way too low. I had around 70psi for 160lbs which is more in line with Fox's recommendations. FWIWI'm 180 in riding gear and I run mine with about 50 psi in the positive chamber and 55 psi in the negative chamber.
Ok!Currently I am running 40 psi to get small bump compliance (one token) with a few bottom outs per ride, I'm looking to fix that. (180-185 loaded riding weight)
Or sell that piece of shit and get a Ribbon coil.<snip>
If the later, I would recommend going for a Luftkappe upgrade if you want small bump sensibility and midstroke support.
You didn't read down far enough.From MRP's website:

- Isolate and tune bottom-out with minimal changes to initial and mid-stroke.

I had lower pressure than that when the fork had problems with stiction from the seal of the air piston. I would check that out if I were you... Just my 2 cents
When I wake up from my Yeti induced financial hangover, I may consider it. That will be next year, though.Or sell that piece of shit and get a Ribbon coil.
Small bump combined with midstroke support? Got that in spades...
Ok, I missed that difference, sorry about that!You didn't read down far enough.
Fox 36, Version D
This new model goes beyond our previous offerings and includes parts
to convert the stock air-spring into an independent positive and negative chamber arrangement similar to the Fulfill™ spring found in our Ribbon and 2017 Stage forks. Once installed, you can now vary the pressures in your two chambers; increasing your negative spring rate to improve small bump sensitivity (a common complaint with the stock spring). This, in addition to the control you have over bottom-out and ending-stroke performance, gives you a radically more sophisticated air-spring that’s incredibly straightforward to tune and adjust!
Those pressures get me to 20% sag per Guerrilla Gravities recommendations. Seems to work for me. I'm guessing the increased negative pressure makes it go through the initial travel a little easier.
No worries. I see what you're saying about the pressures. I can't remember what I ran before the swap, but it is definitely less than I ran in the stock configuration. It feels great though. Really plush and only bottoms when I would expect it to. I think the saying is "If this is wrong I don't want to be right".Ok, I missed that difference, sorry about that!
