First boxxer, trying to set it up, im 220, so i started with 115psi, and i hardly get ANY sag, dropped it to 50 and its close to 30% but too soft, 60-70 seems to be the sweet spot, which is like a 100lb person. Not sure where to begin with anything, so any recomendations appreciated, but more importantly, do i run the boxxer super stiff with no sag, or run it way underpressure?

Do these forks come with oil?

help me :confused:

It's not for a 100lb person. At least not for my 2010 one. Mine have a sticker that's wrong with the weights. I use 50-55psi and get 25% sag at 160lbs

As for setting it up - the base settings RS gives in the manual are a good start. It should also have the correct pressure.

my experience are based on my 2010 Boxxer WorldCup with the updated rebound assembly installed.

i ran 30% sag. psi was about 5-10 under what was printed on the fork leg. make sure you got your usual riding gear/clothes on when measuring sag. i also have a friend hold the bike while i get into riding position. i bounce up and down to make sure i overcome any initial stiction and then measure.

the recommended settings from RS were a nice place to start out, i ended up running alittle more compression and rebound damping.

depends on riding style, terrain, and speed.

In my Boxxer I run 65-70psi. I weigh 165lbs. I Find the Boxxers to be a bit weak in the Midstroke range. Even with 2 Full turns of Bottom Out on.

Sag I get about 10% - 15% range. My advice. Start High and work your way Low...


BUT before any of that Check your Tire Pressure!

Anybody have any official text with this, mine came on a demo 8 (does that matter) So far the pressure is way lower than it needs to be (so what?) it seems i can easily bounce it to the 6 inch mark, shove it to 7, and just barely bottom it out by slamming it with the front brake (i THINK bottom out)

This whole air fork thing is new to me, and this is the first time i havent ran a fox fork EVER. My fox was so easy, drop in a spring u like, set rebound and ride (as compression does nothing)

Do the dials work on these forks? Will i notice any dial turning?

Then your damping cartridge was blown. Compression adjustments on a 40 make a huge difference.

his cart was blown, he posted a thread about it. He was running the soft spring at 220 lbs....... hard bottom out + way undersprung + air in bladder = dead cart

Yup, that would explain it. Why would you not get the proper spring after 6 years and 6 forks?

Preference really, i know it was wrong, but i felt it rode so much better with the blue spring, and i am really biased over the back, so it didnt really bottom out much. personal preference

You're definitely gonna want to run it with no sag if the sticker says that's right for your weight.

No sense in setting it up so it actually works.

Christ. Go to the RS website and download the manual. Setup the sag between that little sag brackets that are on your fork (20-30%) , use the basic settings and go from there. What is so hard in that?

Nothing is actually hard, except that the fork pressures are way off the manual. I dont mind how i have it set up, but i would imagine that undersprung in a coil fork is not nearly as bad as undersprung in an air fork.

It's not rocket surgery.

1. Ignore sticker recommendations
2. Add air
3. Too soft? add more air. Too hard? do the opposite.

The fork pressures are not off normal just the table been printed wrong. Just shift the pressure 1 weight bracket down and you are fine. That was the error on mine. You will not be undersprung if your pressures are not correct acording to a table, you will be undersprung if you have less sag than the fork should. I don't understand why do you see a problem while you have a fork with special sag bracket printed on it so it would be easier to set it up.

did you disassemble your fork, repack it with oil, send it to TF tuned, cut the dropstop in half, replace the seal head, replace the lowers, drop a spring weight, rotate the coil condoms, and install an avy cart?

Ah come on guys, can we cut the guy some slack?Im sure we all have our "dumb" moments sometimes.Demo9 has a legitimate question here...perhaps something is really wrong with his fork.

That said Demo9, what you've said about your previous forks doesnt make sense at all.Running a FOX 40 with zero compression and a blue spring when you weight 220# is NOT a matter of personal preferences and certainly not how it should be ran.Im 150# and Ive been running blue springs with a fair amount of both HSC/LSC pretty much ever since the 40 came out.I bottom out the thing at least a couple of times every day.

Something leads me to believe that ( and I may be completely wrong ) somehow you've got accustom to running an heavily undersprung pogo stick and to you this is how a fork should feel , hence why you seem to think that new BoXXer is SOOOO stiff with the recommended pressure in it...Maybe ???:think:

Here's what I would do, forget about the recommended pressure, maybe something is indeed wrong with it.Make sure you achieve the right sag by physically measuring it.Now (and I dont mean to insult you when I say this) , are you sure you know how to measure your sag correctly it ? You do realize you have to be standing up on your bike in a fairly aggressive position right ?

Even if you think you are very fast, you are not a WC racer and anything less than 20% is just plain silly IMO.One last thing, even if in theory compression settings shouldnt affect your sag, in the real life it does...I beleive it's call suspension drag or something like that but I would take that into account as well.Aim to get 20-25% sag with the compression somewhere in the middle and take it from there...Also , its ALWAYS good to service a brand new fork before riding it. Lube-it up , measure sag and go ride it . . .

Other than compression damping affecting sag (which it actually doesn't in any fork, only SPV/boost valves that close fully have that effect), that post was bang on. Your 40 setups were essentially totally f**ked, if you got used to riding something like that then no wonder anything else feels weird! Yeah it might have had amazingly good small bump compliance when it was run that soft, but it SHOULDN'T have, it should have compromised some of that for stability and big hits like normal setups do.

Why don't you try for yourself instead of asking numerous questions. The dials are obviously there for a reason. plus if they don't do anything then stop complaining since it seems as if the whole time you've been running forks with broken dials/ knobs.

Chance are ill just swap it for a new fox 40 (with a green spring, hate on) Did not plan on keeping the boxxer anyway (came on complete) I just figured i would give it a try since i had it, maybe not. Anybody want a 2011 Boxxer WC?

And fwiw, ill get the fox cheaper than ill sell the boxxer, so no, im not wasting money

I'll trade you my 2011 boxxer r2c2 for it, that way you can just drop the spring in of your choice (I have 3 for you to choose from) and your set like your fox.

It seems funny you are worrying that the rock shox recommendations are off but you don't go by the fox ones either.

I will bet if you take apart your air spring there is no lube on the o-rings and no oil inside the air spring.Do lube and oil your air spring and you will run the recommended air pressure on the leg.

Man I always wondered where the demo love came from but seriously? Buying a new fork because the manual and RM posts here have to many letters?
Seriously even a ****ty fork with proper settings will run better than what you've been doing up to date.
