[Closed] New Fox 36's

Not yet, but I will on Sunday when I pick up my new bike!
They felt amazing when I demo'd them on various different bikes, next step on form the pikes I currently run.
Can't wait to go and get gnarly with them!

From your description it sounds like they are less progressive than previous models else there'd be no need to add two spacers?

Doesn't adding spacers make them ramp up more?

iv added two spacers and max on my air pressure

Just popped a pair on the newly built Bronson, took the new 2015 pikes straight of.
Comparing them to the CTD kashima 34 floats on my old bronson it's night & day.
I found I had to drop the pressure down to 70psi to get them how I wanted them, 30% sag, very supportive platform compared to the 34's, just starting to tweak & hopefully get them how I want them but they're fantastic.

Bike Scene at Giusborough have a demo Bronson with them fitted & a CCDB air CS which I went for too.

Interested in how you get on with them & any adjustments you make.

Cheers

without the spacers they are way too soft, mojo added them for and said it would be better as im a not a suspension guru. i was just curious if anyone noticed the same

Progressiveness depends on how fast you ride and how heavy you are.

IMO I still prefer coil forks and they are pretty linear - progressive springs aren't used in moto forks. I suspect the reason they are used in mountain biking is that up until the advent of procore and wide rims, bikes ran relatively high tyre pressures so need very soft initial strokes to gain any small bump compliance - and thus they have to use progressive springs to compensate and stop the fork from diving to much.

IMO, I'd run lower tyre pressures, take out the tokens and bump the spring rate up. So basically exactly the opposite to how Mojo have tuned those forks for you.

Also, this is one of the reasons why I am going for the Mattoc (maybe a Marzocchi). Both companies have attempted to emulate a linear coil spring with their respective air springs meaning that they dive a little bit more, however the Mattoc supposedly bests the Fox 36 and Pike through rough stuff as it's less prone to spiking. I suspect this is actually due to the linear nature of the air spring. However, the ramp up of the last portion of travel on the Mattoc can be controlled by an external hydraulic bottom out adjuster - which I think is great.

What I'm going to do is just run a procore setup, run about 20 psi in the front tyre and run the fork a little bit harder with the low speed compression cranked up a tad to control the diving. I think this will give the fork more control without feeling spikey.

Pretty much all the reviews say the same as this one, if anyones interested.

bump the spring rate up.

but you can only change the spring rate of an air spring by changing the geometry

I'll be sticking with my 2011 Van RC2, which fits 650b wheels fine, for another couple of years. only a c.200g weight penalty anyway

but I like Tom_W1987's approach

Got 2 pairs of them, stiffer than a Pike. Its taken me a while to get them how I want them though but they are now almost there.

I've got a set on my Spitfire after initially building it up with Sweeps and they are bloody fantastic in comparison. For me I've just gone with the stock setup suggested by Fox and it's been great so far.

I like the fact that they sit higher in their travel than the Sweeps did and they track a lot better as well on repeated hits as I found the Sweeps got knocked of their line too easily in really rough stuff. Plus given that they are 36 compared to the 34 of the Sweeps they're noticeably stiffer.

Very similar experience to you, I had 34 floats on my Bronson though they're good I rode a friends new 650b Orange five fitted with new 36s, big mistake as it cost me a small fortune on the new bike build, the forks track very well & as you say they sit much higher up in the travel, very supportive no diving either though it took three goes to get the initial feel & sag right so it's just minor tweaking from now on hopefully.

i cant run any lower than 35psi in my tyres due to being 17st i seem get loads of flats then. im at the max psi on my forks too which is 97psi.

See what they're like with one spacer and same pressure Biggs.

This ramping up you mentioned can you please explain???

Sorry if I'm wrong in this assumption, but isn't the benefit of adding tokens/spacers to allow you to actually run lower pressures in the forks?

Running the max air pressure for your weight with spacers will make them like pogo sticks so I would expect this is why you feel they "ramp up", maybe try dropping the pressure in them or take the tokens/spacers out and run the same pressure.

If you still can't get them feeling right for you maybe invest in getting them set up specifically for you by Mojo or another fettling company.

This ramping up you mentioned can you please explain???

"Ramping up" is when a fork gets progressively firmer towards the end of its travel. So you can run a lower pressure making it more supple in the first part of the travel but it won't bottom out easily as it ramps up enough further into the travel (usually achieved by volume spacers)

Pedantry, but you can only change the spring rate of an air spring by changing the geometry, specifically the diameter of the air piston, so this isn't actually a possibility. Changing the air pressure only changes the preload.

Really, so adding air to an air spring is only like adding preload to coil? Adding preload to a coil just means the initial break away force is higher.

This is over my head now if any engineers can care to explain.

Fox call it spring rate
