SC Bullit recommended fork sag

[Thedude74]

Hi

So understand the sag is very much a baseline and individual setting, however I’d be interested to know what sag Bullit owners are set to based on a Fox 38 fork?

Fox guide recommends 15% firm 20% plush, SC suspension setup guide gives no sag advice apart from recommended psi based up weight. On my Zeb I ran min 25% fork sag

The fox setting of 20% for a 170 fork seems to be more on the firm side. Plus SC recommend 30 shock sag - the balance would seem off to me based on the Fox 20% plush setting?

Thanks

20% on a fox 38 170 is 34mm it doesn't matter what bike it's on.
I run mine around 30mm.
30% on the shock is pretty much standard.

Interesting - I know it’s a totally different fork to the Zeb Ultimate (plus different frame etc) but 20% or less just seems firm . Does the Fox prefer to sit higher in the travel to get the best setup?

If it's the older grip damper, then they are notoriously harsh.

Running them with more sag does not work very well.
Apparently the ebike damper shim stack tune is worthwhile.
Running the slow rebound fully open helps as the damper oil goes through that first, so closing that restricts oil to the rest of the circuit.
I don't know about the newer X2 damper apart from it has a bigger shim stack and offers more adjustments.
The zeb would be easier to alter as it will be more user/ diy friendly.

I have only bottomed out my shock 5-6 times. My forks…never. It’s not a very nice feeling when you bottom out your fork or shock but it can happen for a number of reasons. Wrong suspension sag, extreme drops etc. your right though, 30% is the recommended baseline setting. It mostly depends on your style of riding though.

30% sag suitesme and my style of riding, just fine. I usually record the psi amount for air shocks or forks so I can set the psi again if there any noticeable changes. What is critical for me is the 3 points where I touch the bike …grips, pedals and saddle. Suspension settings play a big part in that.

I tried %20 sag before and I don’t like it. Instead I changed my saddle, the grips, the bar, pedals and set the suspension sag to %30. It’s not perfect but it works for me.

Front, I just go by psi in the fork. I start with the recommended psi by the manufacture and adjust psi from there by riding feel and riding situation/condition.
For rear, I set sag for the first ride as a starting point. After the first ride, I go by psi.
I might check sag for rear once in awhile just to get an idea where I'm at for my curiosity but I don't use it for further adjustment.
The reason for that is that sag measurement is far less accurate than checking psi, especially the front.
When you change just a few psi in front, I don't think you can really see that in sag.

Firm? More sag results in a higher spring rate, which can result in more harshness over small bumps at speed. Go with the recommended sag.

I have a bsolutely no idea what SAG I have on any of my bikes! The reason being I only use recommended SAG when first setting up a fork......but then play with rebound and compression in conjunction with adjusting PSI in the fork to achieve the performance I want on each bike. Once I find that I only record the fork PSI, rebound and compression settings. The only exception to that would be if the fork offers separate Low and high speed compression settings. In that case I may have a more open HSC for most rides but with the ability to increase HSC for a ride with additional features.

On a Fox 36 or 38 I would suggest using 20% as a starter provided you are setting SAG when the "ready" position, for a bike you expect to be mainly up on the pedals rather than seated: 25% if setting SAG seated and the use of the bike will be mosty in the saddle. After that, it is by repeated runs with the bike playing with different rebound, compression AND fork PSI levels. Most riders objectives are to find a setting that is plush, runs the fork mostly in mid travel, and does not easilly bottom out.............on typical terrain that bike is used for. Virtually any setting is a compromise if you use the same bike for very different terrain. For example on my Enduro bike I have no expectation of plush performance on rumbly gravel.....that sort of terrain is not the priority for that bike.

It is virtually impossible to get any meaningful guidance by comparing other rider's settings unless
your bikes have the same head angle, you and the other rider are the same weight, the forks used by both are identical ( quite a bit of variation even by manufacture year with Fox!), you both ride the same terrain with the same intensity.

Thanks appreciated

I’m not really looking to use the settings of other riders, more so just wondered if there is a ‘stock’ base sag setting for the fork specific to the SC Bullit - then I tune from there.

I’ll kick off at 20% initially and then go by feel and psi.

Cheers

Personally I wouldn't bother with percentage of sag on the front. On the rear, yes. Just try the recommended air pressure in the fork and adjust to your preferences. There are so many other factors like bar height, stem height, compression, rebound settings, etc and not to mention the trails you're riding. You have to find what suits you best and the trails you ride.
