Tuning the 2015 Fox 36 on HD3

CrashTheDOG · Feb 24, 2015

Thanks for all the feedback guys. I pick up my 36 equipped HD3 tomorrow and appreciate the insight on setup. First Fox fork since '09.

I'll have to look into getting a digital pump and tire gauge. I guess I should now that I have carbon rims!

Sceptic, I wonder how critical a super accurate shock pump is if you always use the same pump you used to established the desired sag. Especially when you use a pump like the Topeak DXG that has the two stage valve that prevents air loss when you remove the pump.

I would expect that from a 3' drop to flat. Unless your normal trails include more than this then I would say you are close. For my local riding I run 55 psi, but at Mammoth I run 65-70. If you are looking for a do it all setting then 60 PSI is probably close.

BTW is that a Butcher up front on the 741?

SP- Thanks! I'm liking this pressure. Feels pretty good. That tire is a Minion 3c that is the stock tire in the build kit. Woking pretty good so far.

Now that I've gotten used to running 60 psi, I'm finding it a bit harsh in a few places, so I am dropping to 50 psi this week. Maybe it's truly broken in now, and I'm getting the true feeling of the fork? Still using about 3 clicks of HSD, but slowly reducing it. So now I'm running 50 front, 150 in the DB Inline.

Scepticshock, how much do you weigh? I weigh around 140 with riding gear . . . found the fork to work well for me - and get full travel - with all volume spacers removed, low speed compression set about 8 clicks out from closed, and HSC fully open

scepticshock · Mar 16, 2015

With gear, and pack full of water abut 176.5. I haven't gotten to taking out any spacers yet. It may be something to try next. Right now I will try air in the 50-55 psi range and see how that goes.

thats the ticket for you scepticshock, try those settings

I tried it at 50 Psi no HSC and 8LSP and it worked pretty good. Today I took out the spacer and it made a huge difference with how much travel I got. I dialed back in 3-4 clicks of HSC to balance that a bit. So far so good.

Hey guys. I need some input. I"m a little heavier than most people responding on this forum at around 220 lbs. I"m currently running around 80 PSI. but I can not get full travel out of my forks. Maybe I should put my HSC full open? I think it's about 4 clicks from full. Any input?

scepticshock · Apr 9, 2015

As recommended above, I would remove the air volume spacer. You will get noticeably more travel. Then see how much HSC you need for the type of riding you do.Are you running 4 clicks from full closed? That sounds like a lot. 0-4 from full open sounds like what many here run. I'm running 3 from full open.

Junersun · Apr 9, 2015

Thanks.. yeah I"m riding 4 from open. I would have though for someone as heavy as me, the volume spacers would help! I'll give that a try. thanks.

Hope you guys don't mind me chiming in a little, since I'm not on a HD3, but on something similar (Canfield One), and have a 2015 36 fork on it. I was a little concerned about the harshness and lack of full travel. I'm 172 lbs without kit, took out the volume spacer, ran 52psi, 4 in from open on LSC, full open HSC, 5 from open rebound.

Still wasn't thrilled with the harshness/lack of full travel so searched and found the zip tie/seal trick to release any pressure in the lowers that may have built up. That made a huge difference for mine for harshness and full travel ability. steps: Let all the pressure out of the spring, peel back the stantion seal with fingernail and work a small zip tie in there until you hear a pssst. Then do the other side. I had to up the psi and add in some HSC as I was getting full travel much more often, and it felt a bit less harsh on the stutters too.

Another thing I found out is apparently Fox re-tuned the shim stack in the cartridge around Oct last year to make it a little more forgiving. I haven't updated mine but will ask for it when I need service. I found this info over on the susp forum in the 2015 36 thread.
Hope it might help someone. Cheers!

YMMV, I'm about 180 with gear. After setting sag I settled with 7clicks in LSC and 8 clicks in HSC. I used 90% of the travel riding DH stuff.

The apparent damping inconsistencies with this fork are disconcerting.

What pressure are you running?

PhoS · Apr 9, 2015

Wasn't paying attention, I pretty much stick to sag measurement sorry.

Removed that damn volume spacer and now it feels phenominal! Thanks guys. Next on the list angleset -1 degree!

scepticshock · Apr 11, 2015

Cool! Glad it helped! I'm not sure who has found those spacer useful. I guess Fox was being overly cautious about bottom out when they developed it.

Keep us posted on the angleset, and how it changes the ride. Just wondering if the angleset off the older HD would work on the HD3?

It wont unfortunately. They use a zs56. Old model i think use a zs49

alan1 · Apr 12, 2015

Running a -1 degree angleset on mine, bike is just as playful, no probs climbing steep tech either, feels more planted going down hill through the rough stuff, for my riding there is no drawbacks with slacker headangle, for reference running a 160 fox 36, roval fattie wheels with maxxis minnions DHf and DHr2, only minor concern for some could be the low bottom bracket mine is only 335mm, I havent had anymore pedal strikes than usual running 175 cranks

Nice! Did you use a zs or an ec? Im thinking if i use an ec then that will keep my head height the same so my bb height wont change. Im not concerned though. Itll still be higher than a nomad

I got a works components headset the bottom cup sits flush with the headtube, top cup add's 15mm so if you currently run spacers under the stem there will be know difference in stem height
