Answered Fox Suggested Sag Measurements

[pgtips]

Ok I would like around the 27% sag settings on my rear shock.
I just keep looking this table from Fox is and confusing the shite out of me!! I just don't get the way it reads. Can someone help please? What mm would you use to get to close desire settings of 27ish% ?

Your 2019 Levo has a shock stroke (travel) of 52.5mm. The Levo has a 150mm of travel at the rear, so your 52.5mm stroke has a ratio of 2.86 (2.86*52.5=150) to get to its 150mm travel at the rear.

If 51mm (as per above table) at 13mm sag = 25%, then your 52.5 needs 13.33mm sag to get to 25%.

Aim for 14mm sag - that'll be good enough to get to around 27% sag. No need to faff around any more than that to get it exact!

Cheers Rob......my fault I dint mention that I changed the shock to 2019 FLOAT DPX2.

As long as you got the correct stroke (52.5mm) then the calculations remain the same. Are there any codes / numbers on the box?

There is codes but in the fox site has no info for it!!! Strange.
I see how it reads now.......must have mental block or I'm just mental lol......Thanks Rob, I got it now mate

Also another question. To archive the 15mm sag I'm almost at 300 psi which is the maximum pressure for the shock ( 104 kg ) Do you think I need spacer in there?

No probs!

Fox dont actually list one for the 2019 Levo, they kinda get custom made. They list 210x50 (not enough stroke) or 210x55 (157.5mm travel). I think they custom make the Levo ones from a 210x55 and reduce the stroke to 52.5.

Yes this is custom made to 210x52.5

Spacer wont change sag, it'll change the progression of the shock. I'd try where you're at first before changing anything else.

Many thanks Rob....... I feel silly now as is pretty obvious when you explained it lol.

Nah, it's not obvious at all! They do it that way (shock stroke / travel) as the 'travel' depends on the ratios of the bike that they put it on. That same shock could have a travel of 140mm on another bike...

And I only know as i just got the exact same shock.. and did the same setup last night!!

You just been nice to me

Thanks Steve...... very good read

What is the largest spacer you can put in compared to psi? My spacers arrived today, just don't want to install the wrong size. Tia.

 

[steve_sordy]

Nothing to do with psi.
When I first tried adding air tuning spacers to my Fox shock, the pack arrived with three spacers for my shock and two spacers for a larger shock. Of the three (S, M, L) spacers for my size of shock, I started with the smallest first (O.2 cubic inches, if I remember correctly). I noticed two things: First, there was an immediate increase in mid stroke support so that the shock was not compressing quite so much. Jumping to flat, the fork and shock travel were more in line with each other. Second, I needed less air pressure to get the same %sag as before, making the shock more responsive over small bumps.

But of course , if the small one was good, would the medium one (0.4 cu.in) be even better?
So I gave that a go, but it made the shock feel too harsh. I left it in for the rest of the trail just to make sure, but I didn't like it, so I replaced it with the small one. I didn't even try the large one (0.6 cu.in). I'm sure I still have the M & L spacers (+ the two for the larger shock) somewhere in my toolbox, but I don't have that shock anymore.

The job of fitting is so simple to do that I saw a magazine write up that they did it trailside. My first fitting was in my garage, and it really was easy as I didn't have to remove the shock. On the test ride, I actually removed the small spacer and added the medium spacer by the side of the trail. It really was that easy, and quick to do! However, I must have introduced a speck of grit because at the next shock service, there was some internal scoring and it cost me another £60 for the damaged part. So, don't do it trailside, no matter how easy it is!

I was just looking at the DPX2, is it a good fit for the Levo and do you need to remove the bottle cage?

It fits well and you can leave the bottle cage if you want too, but there is no much space to slide a bottle from the top. Better off using one of the side load bottle cage's if you still want to use it. I never used mine as I always carry my Camel backpack with the blader. Even when I go out for a quick blast.

Thanks for that. Did you get the shock travel adjusted from 55 down to 52.5? I’m paranoid that I’ll damage something if I don’t.

I purchased mine from here as I have most of my shocks and forks. They don't advertise the 52.5 but if you give them a call they usually have them in stock.
