So question what is your sitbone measurement? On the Sitero narrow measurement to the front of perforated saddle and wider further back. There needs to be good drop from saddle to bars.

Not sure exactly, but I'm pretty narrow. If I scoot back and forth on the Sitero to where it feels like my sitbones are at the edge of the saddle (or close to it) ... the Sitero measures 90mm

I made the switch. Then switched back. I had chafing issues with the sitero that I could never work out.

I went from Adamo to Cobb (V-flow MAX) and was very happy with the results.

I've not found instruction that says what is the recommended tilt for the saddle. With the Adamo, their instruction is to have the saddle rails be level, which then gives a bit of tilt if you put a level on the saddle, back to front.

Adamo is drunk basically when it comes to tri set up. They set up all their saddles like a road bike even if they tell you its a tri set up. Its also why their saddles are awesome but too wide a lot of the time but that's a different post.
So, get your smart phone out and download an angle app (any will do). Put it on your saddle where you sit. Play around with it for comfort and don't go more than 2 degrees down. Same with the sitero and pretty much any saddle you use.

Second question would be, if others have made this switch, where did you end up positioning the Sitero fore/aft compared to the Adamo?
Don't worry about sit bones. You shouldn't be on your sit bones anyway - pubic rami is where you'll be supported if you're on it (it defined as any saddle) correctly. It also depends on which adamo. They have different 'lasts,' lengths, and padding. I've ridden a bunch of the alamos (am currently on the PN 1.1) and have ridden the sitero multiple times. It is super comfy if you're upright but a more rotated position just didn't work for me because the relief doesn't go all the way to/through the nose like it does with adamo(s).
You'll want to make sure both saddles have the same set back from the BB. Not physically but effectively - e.g. where you sit on it. Meaning, you may have much less setback w/the sitero if you have something like the prologue.

After that, give it some adaptation time and its a one way ticket to Crush City.
oh, and p.s. recheck saddle height afterward, it can move quite a bit with a new saddle and fore/aft positioning. If it moves more than a cm you may want to recheck drop/reach too.

Neither as they are both painful
- Specialized Power which is an evolution of Siteros

I dunno ... I've found the Adamo instructions to be right on for me. I have the TT saddle ... probably 7 years old now, before they changed the name and made more models.

That means there is a fair amount of tilt if you measure back to front. But the front part, where I actually sit, is pretty level or just slightly down

I'll sit back farther on the Sitero (still maintaining same position relative to the bike, but on a spot farther back on the saddle). Just curious what others may have found with this. So I know the Sitero will result in less setback.

I'll have to play with the Sitero then, with respect to the tilt and see what feels right

thanks for the input

Not obvious, but the iOS Compass app has a built-in level (swipe to the page.)

I discarded OEM Adamo installed Spez Power. The most comfortable saddle I have ever had rather MTB, road or tri. Forget about it. Have Spez bracket for 2 bottle cages bolts into saddle. Awesome.

This....

Went from Adamo (good cushioning but too wide in front, not enough taper),
to the super hard and 'edgy' Sitero (better shaped, narrower up front but super hard and with 'plastic' edges),

to the Specialized.....which looks like a traditional saddle, but is not (unique shape and taper).

Super narrow up front and just fits my anatomy perfectly (narrow hips....somewhat bigger thighs).
