Zeb settings

Hi guys. I have just realised that my LSC knob just turns noth ways but there are no distinctive clicks.

It just seems to spin freely to a stop each direction but doesn't click whatsoever.

I have taken the 2mm hex screw out and removed the dials but nothing obvoius wrong.

Has anyone else encountered this issue. Can't find any info on it at all online. Its a Zeb ultimate

I would imagine the adjuster is still working if it still has stops at both ends, but the detent that give the click is messed up. Very annoying for sure. Could just not worry about how many clicks and go by 1/4 turns?

Thanks for your reply. Bike shop said the same thing.
What could mess the detents up? Rust?

Terrible design if so.

Ride it hard for the season and then send it off for a service and have it fixed then.

Local BS replace the indent band. Had one spare. Was corrosion. Less than 8 months on the bike.

Very poor

just got an EVIL Insurgent with the 180mm zeb and it seems super soft and way too much sag at suggested psi for me (66psi) at 185-190lbs but mine is brand new. Does anyone know if the zeb ultimate comes stock with any tokens? Ive heard they come with one from the factory.
P.S. I primarily freeride. Big jumps drops etc.. but come from bmx/moto so MTBs are pretty new to me. want a firm setup that won't bottom out and maintains speed but don't wanna run super high pressure. guess I need to try to buy a couple tokens, (if I can find any online)

im 210 and was running like 69-73 for 20ish depending on tracks/locations. im guessing you need to equalize the fork. common on rockshox forks

not sure if its too bad of a setup, i like it personaly.
so feel free to give me some constructive criticism or just criticisim.
53 psi
fully open rebound
4 clicks lsc from open
1 click hsc from open
125 lbs
15% sag

Been working with pressures. And speaking to a few suspension specialists. And common theme is people seem to run rebound too slow. Have bottomed put a few times on rockshox given recommendations for the fork. I’m 82/83kg recommended was 64/65psi still felt lacking support so trying 70psi and running the rebound a little faster 11 from closed and see what that feels like and adjust accordingly. Looking for the supple off the top feel but also support which hopefully will get now with the increase in pressure..

The stock air recommendations seem low. Ive been bottoming it out regularly every ride, added some PSI and turned the HSC up (1-2 clicks) and its WAY better, depending on the trial.

However I still needed some bottom out resistance for the wheelie drops and huck to flats (slow east coast tech). so I went to put in air today and noticed I had the fork already at 66 PSI.

Im 160lbs, 165 with gear.
Recommendation: 52-54PSI.

Since my PSI is well above recommendation, and the fork feels amazing otherwise. I'm going to try to add a token which puts me at 2 tokens. 66psi and 1-2 clicks of HSC. Fork is 170mm 29er

Hey guys, just found this thread. I agree, these forks are different than other rockshox forks I’ve owned and do not need that much air pressure to get right. They get harsh very easily, in fact I find the recommended psi unbearable. I think the issue with all the off psi numbers is the shock pumps everyone is using. I just switched to the rockshox digital pump and it’s completely different psi reading than my old standard rockshox pump. Anyhow I’m 175lbs running between 50-57 psi, still trying to figure it out.

Really interesting seeing the wide range of set ups for people. I’ll post mine in case it helps anyone. Aggressive rider, steep, drops, jumps, etc. PNW to start and now riding dry and rocky SoCal.

I’m 170lb without kit. Running my 170 Zeb now at:
56-57 PSI, no tokens
1 click HSC
7 clicks LSC
6 clicks rebound.

I had a heck of a time finding the sweet spot, but I think most of it was due inaccurate pump readings. I was running 62-65PSI and it felt harsh. Brought it down a bit and it was a noodle with no mid-stroke support and would dive on the steeps (suuper plush though). Came up to 57-56 and I use all the travel a couple times a ride but no harsh bottom outs. Would like to try adding a token and dropping a PSI and losing the click of HSC.

Hi everyone,

I also see a very wide range of settings and i was having difficulties to understand what was wrong with my zeb but eventual i think i have somehow sorted out my issues and i also can safely say why people do have so wide range of settings.

So according to my understanding and my experience this fork is affected massively from the trapped air inside the lower legs probably because it has a huge volume there.

So to sum up my story real quick.

I am 90kgr (198lbs) with gear and i ride an ebike.
When the fork was new in order to use full travel i was using about 55-60psi.
Trailhead recommends 78psi (for 90kgr on an ebike)

Trying 78psi was like a joke i couldn't use more than 70% of travel on a full race weekend and the fork was very very stiff.
Actually it was out of question to use such a setting and i was wondering why on earth rockshox suggests this pressure and was also wondering how on earth people could ride this fork with these pressures.

Then i saw some videos on YT regarding trapped air in the lowers and i used a zip tie (i know not the best way of doing it) and i removed the air from the lowers just for testing. I was not convinced that it will make any difference to be honest.

The results amazed me and they were totally unexpected.

So with no air in the lowers i managed to use almost full travel of the fork just by pushing it with my hands (i was not even on the bike) at 78psi!

So doing tests back to back with the exact same psi (78psi), with air in the lowers i cant push the fork more than about 40% of its travel and without air at all in the lowers i could easily push the fork down to almost 80% of the travel.
The difference is absolutely huge, and obviously this is why FOX38 have bleed valves in the lowers. Because on such a large air volume the trapped air does play in important role.

So sharing the air settings each one of us uses, makes no really sense when no one of us knows how much air is trapped in our lower legs and since we cant somehow predict how to deal with it.

I shared my thoughts to you just in case i miss something here or just in case i help others.
So please if anyone knows / has a tip please advice.

At this moment i have set up my fork as follows:

I equalised the air from the lowers while holding the fork at 20% sag.
This way i hope - believe that from 0-20% of forks travel the air in the lower legs acts like a negative air chamber (sucking the fork in) but from 20-100% of forks travel the air in the lower legs acts as a positive air chamber (trying to extend the fork to full travel or to 20% travel to be precise).

So at about 20% of forks travel the air in the lowers is neutral.


Thanks

So…

Indexing clip on the compression adjustment got corroded so sent it in to get serviced and at that time I got it tuned too by the company who serviced the fork

They have tuned it based on my weight, riding style, and leverage curve of the bike.

So once I received my fork back the settings which the fork was tuned to were as below

I’m a 83kg rider with kit.
68 psi
HSC 3 clicks from maximum
Lsc 6 clicks from maximum.

Just got back from bike park and first few runs yes had hand pump which I expected with the increase in pressure. But after that got use to it. Have support,grip and confidence to point and shoot which has worked really well at bike park and can confidently say will be keeping the settings for local mtb trails too.

Anyone knows or can confirm if the air shaft of the zeb ultimate is wider than the airshaft of the zeb charger?
I ordered a service kit for the ultimate and it doesn't fit. The lower seal head of the ultimate is designed for an airshaft with bigger outside diameter.

If you also realize that the airshaft itself is acting like a negative air chamber in the zeb, those of us having charger forks, we can increase our negative air chambers just by changing to a new airshaft.

By the way i have ended up my fork's setup and i use 75psi with one token and its simply amazing.

Take care everyone
