You can use a Shockwiz on any compatible fork mate. I like them myself. I've used lots

 

The best way to use these is to ride a trail section over and over. Then every time you run it tweak your settings and start a new session on the SW.
That is exactly how I DIDN’T use it. I would just do my complete ride and check and tweak after the ride. By doing it this way it takes a lot of rides to dial things in.
Don’t expect miracles. On my old Giant Trance the SW dialed in the Fox Rhythm/DPX really great. I felt like it was absolutely nailed when all the settings were green.
On my next bike (Orbea Occam) the green settings never felt right and I eventually gave up and tweaked by feel. I might throw it back on to see if I can get things dialed as my Occam still doesn’t feel as dialed in as my Trance.

 

Is it worth getting one of these little dudes in 2023? Are they ever going to release an updated one?

 

You're better off with a new hardtail than going that way

 

I'm not entirely sure these are worth using for anything tbh. I have 2 I've tried using and I've never been all that satisfied with the results. It practically tells me to run compression wide open on every fork and shock I put it on.

 

Does it spit out what your dynamic sag is while riding? That metric alone could be useful I would think

 

It does

 

Question guys.

Lyrik ultimate. 150mm, charger 2.1
Rider weight 63kg. 64psi.
Shockwiz shows
HSC fully left in red. Which way do I need to change his HSC? It's fully + currently on bike. So I need to - it? Or am I reading it completely incorrectly?

 

You're correct. The shockwiz is telling you to make HSC softer which means you would reduce compression damping by turning the dial counter-clockwise.

 

Does red mean too much or too little?

 

Yeah that's the bit i'm confused about with HSC, i've googled but i'm still not quite sure.

So his looks mostly like this.
shockwiz by Steve Weeks, on Flickr

He's got 5 clicks of HSC according to Google and we're maxed on +

So that's where the question is... do i need more + or more -

 

It literally says "make softer" right under the red tick.. so make it softer, that means HSC dial counter-clockwise...

 

Aye, that's what i was hoping/thinking. That's excellent because obviously i can't go the other way

Will get it tested hopefully on Sat, if not, it'll be practice Sun morning before racing.

 

Not sure if this will be helpful for anyone or if it was already mentioned in the previous 100 pages, but here are some CR's values which I measured:

RS Lyrik 150mm, MY 2019, B1 airspring:
0 token = 2.1
1 = 2.2
2 = 2.4
3 = 2.6
4 = ??
5 = 3.3

RS SuperDeluxe, MY 2021, 210x55
0 token = 2.3
1 = 2.4
2 = ??
3 = 2.7

 

Can anyone tell me what the CR should be on a Pike 140 with C1 airspring and one token? I keep getting 3.9 or 3.4 and those numbers can't be correct. Not sure what I'm doing wrong. With no token I got a 2.6 which seems correct. Thanks.

 

My Pike 140 with the original Debonair spring is 2.1 with zero tokens and 2.4 with 1 token. C1 airspring may be diff but certainly 3.9 with one token has to be way off. You're not running the C1 spring on an old (2017 and earlier) Pike are you? (ie, a Pike that isn't compatible with it).

 

Put 10psi in the fork and set it as the baseline air pressure. Then with the app open compress the fork to 20% then 30% then 50%. Make sure the app reads the correct sag. If it doesn't adjust the CR up or down until it does.

 

I'm pretty sure that 2.6 is not correct either. It shouldn't be that far away from Lyrik@150mm.. If my calculations are correct, Pike @140mm should have ~2.1 with 0 tokens, and ~2.2 with 1 token.

 

Either you are measuring it incorrectly or there is something wrong with your shockwiz.
Could you please post the SN of your fork so I can double check it in my calculator?

 

Thanks for this. 37T92468952

 

Well that's for sure 2.1 to 2.4 max with 0/1 tokens.

 

Thanks. Is this with the C airspring that I have installed? The fork came with B.

 

Yes, although C1 vs B1 doesn't make such a difference in regard of CR value with 1 token (about +0.1).
I don't know exactly the effective length of positive chamber in Pike, but I do know it in Lyrik and from that I assumed the Pike's length which should be about 2 cm shorter. And from that I get 2.1 to 2.4.
Even 3.4 you measured before is ridiculously high for 1 token, because that would mean 10.3 with 4 tokens.
Are you 100% sure you are measuring it correctly? Fork works ok?

 

Thanks guys, yes I saw Alexbn921 posted a similar method which I tried. Dano91 I'm pretty sure I'm doing it right and my buddy who I borrowed the Wiz from tried it several times and also got the same numbers. Using Alex's method about 3.4 got me to 100% at full compression, but the intermediate numbers of 20% and 30% compression were way off what the app was showing. I'm going to remove the battery and reset the device as something sure seems to be wrong. Vitaflo thanks for taking the time to recheck yours. Will let you know. Thanks again all for helping out.

 

Ok, I removed the Wiz from the bike and inserted the battery backwards for the reboot sequence. Reinstalled and calibrated and got 3.4 CR again.

 

I should also note that the 3.4 seems about right when compressing the fork and looking at the reading on the app. Is there something wrong with my fork?

 

Ok, now I'm confused - first you said that markings on the fork were off and now they match up? At the full top out, do you actually have 140mm of stanchions visible?

 

When I did the test with 10psi and manually input CR of 2.4, the markings of 20% and 30% did not correspond with what the app was saying. With the 3.4CR that the Wiz computed and with 60 PSI in the fork the 20% and 30% marks seem to match up.

 

I recently got a shockwiz to help tune a Fox DPX2 which I added to my Trek Fuel. When the shock is in its "open" mode, I got most of the settings in the green except compression. When I rode with the shock in the middle "trail" mode shockwiz the results got worse. Given the Trek Fuel doesn't have much anti-squat I normally pedal in the trail mode and descent in the open mode.

Should I try to find a balance between both modes or just ride in the open mode? It seems that even in the open mode the compression is still a bit stiff according to the reults.

The Fox DPX2 usually have very very little compression damping. Either you've got the one they made with too much or Shockwiz just can't make sense of it.

 

Have you replaced your air spring seals?

During last major service. I cleaned and greased air spring about 500 miles ago. I would think I'd be losing air if the seal was shot.

I'd tune it for descending and not worry about the other modes (also, iirc the instructions say to use it w/ the shock in open/descend mode since climb/pedal modes basically just close off your compression circuits).

 

OK. Shockwiz question, 2023 Fox 36 Factory @ 160.
Disclaimer: New fork was just freshly serviced by me. No spacers installed. Fluids and grease correct. I have done calibration several times, compression ratio is 3.2. Tuning profile set to balanced.

I weigh 195 pounds. Fox recommends an air pressure of 91 psi for this range. I'm at 79 psi currently, and the Shockwiz tells me to remove air, remove spacers, remove HSC, add LSC, and slow down rebound.

I'm scratching my head at reducing pressure. The trail I've been testing on is very rooty but only small drops, and is relatively flat. Is this normal Shockwiz behavior? The last thing I want to do is tune the fork to a place where I get diving under hard braking on steep trails.

Any advice on interpreting this would be quite helpful.

For what it is worth, the fork feels pretty OK, rebound feels fine to me, and it does need more compression as it is verging on "divey" when I grab the front brake - hence the concern about dropping more pressure.

It can only offer tuning advice on what it sees.

What's it giving you for dynamic sag?

 

18% is what I remember seeing. I'll have to go check.

edit: 19%

That seems reasonable. Try a different profile? Shockwiz just gives you a starting point and maybe you and the SRAM engineers have different ideas of what "Balanced" means.
