I have been cycling for a couple of months and I have saddle soreness. I use a Triban RC120 (everything stock) and a Van Rysel D100 home trainer.
My sit bones’ centers are roughly 12cm apart (picture 2)
The Triban’s stock saddle is 12cm (a bit less) of width in its largest section (picture 1)
I have pain both on my sit bones and a lil bit on the perineum.
The pain occurs regardless of my position on the bike: upright with the hands on the handlebars, or more aggressive with the hands on the brake levers and with the pelvis tilted forward.
Saddle height, tilt and shift done by a professional bike fitter, who said I should try his fit before considering a saddle change but I still have pain.
Should I buy a larger saddle?

Need 140mm saddle
Yes. Try a 145mm
Besides the wider saddle, take into account that indoor training is way worse on your ass, because the bike is way more rigid than it is when cycling in the real world
Also, I tried using cycling shorts with 125 kg/m3 density but no improvements
Your sit bones are effectively on the outside air of the saddle not on the saddle wings. I would go wider
The rule is typically sit bones plus 20mm. So, you should be on a minimum 145mm saddle and could probably run a 155mm as there is typically little penalty for “too wide” and lots of penalty for too narrow.
The other user is right too, you should add some sort of motion to your trainer for additional comfort. I can’t go over an hour with a fixed, rigid trainer. See if you can get some trainer feet or a rocker plate.
Besides the wider saddle that others have recommended, maybe try rollers instead of a stationary trainer, or do some of your training out of the saddle.
The specialized calculator for saddle width to sit bone width is pretty spot on
I would return to my fitter and point out the issues. As they did the work to get you where you are, and that seems to be the only problem, changing the saddle MAY change other Equally important parameters. This is what you paid for!
Just asking, but how long have you been trying the existing saddle and how quickly does it become painful? It’s normal for the first 2 or three bike rides of the season to be relatively uncomfortable. I don’t know how but the body can somehow adapt a bit.
Been there, same measurements, i had a 130mm saddle, now i ride with a 144mm. No problems.
It is most likely not Your saddle. Saddle height, reach and setback are much more common causes of the issues you facing. But without video or pictures, its anyones guess really.
Bike fitting with saddle analysis will save you a lot of money in the long run. I am on my 8th saddle along the years, until I found one that felt proper.
Sit bones should land on the meaty part of the saddle, around where the 1 and 11 or 2 and 10 are in your first pic.
Are you wearing cycle shorts with padding? Are you changing position often, like you would in real world cycling?
