Ohhhh my backside...lol!!!
 

I know there will be many opinions on this but there were on my computer post also which led me to the one for me after reading and checking all the posts which I would have never known existed...so Thanks all for that!!!!.Got a 2021 Specialized sirrus x5.0...Love it !!! except for the fact that being 65 the "in house butt padding "...lol that was there in my youth has migrated in the form of love handles..so I want to start biking again to trim those down!!! Stock seat is gorgeous and sleek..but it is killing me...Need to find a more comfortable one that isn't obnoxiously huge and would go with the flow of the bike..All opinions are welcomed as I known there will be many but this is how I learn what's out there that I may have never known of...All opinions respected and appreciated!!! Thanks all and thanks all for leading me to my Xoss bike computer, which I would have never considered unless I posted!!

The secret to finding a comfortable saddle is to try lots of saddles. There is no rule of thumb to narrow the choices other than that too soft itself can cause discomfort. Some bike shops may have a loaner program to help with selection. In my case, I found over time and a number of different saddles the shape best suited for me.

I agree with the above, but it takes a good many miles to break one's butt in. How many miles have you ridden so far on the new saddle? You've got to give each candidate some time to find out if it's wrong or right.

Also, how far do you expect to ride? I've got 4 seats that are good for 10 miles. I've got one that's good for 45, and that's as far as I have ridden. If I go for a 62 miles, that saddle may or may not work for me.

It also helps to consider the problem critically, so notice where you hurt and when in a ride.

ziptie the living room chair over the seat? It'll ride like those late 80s early 90s Broughams.

Get some padded riding shorts or padded underwear to wear under regular shorts.

I wear full kit when I ride but when I ride with the family I wear padded tights under regular shorts. Last week I went of a family ride and didn't wear anything but plain shorts. Wont do that again.

A good seat is wide enough for your pelvic bones. padded shorts and extra foam on the seat will do no good if it is not wide enough. The selection is a personal problem. If the seat is causing more than muscle pain go a little wider. I tried a Brooks Pro in 1978. Right out of the box it was comfortable. I have used several models since then but never there narrowest saddles. The more upright you sit the more weight rests across your pelvic bones. I checked out the Bicycle you posted about and that looks like a nice lightweight racing seat with the minimal material for someone riding crouched on a road bike.

Early in the season I will wear a second padded bike short. Also works well for longer rides as long as the weather is relatively cool.

I'm a big fan of WTB.

I started riding last year on a similar bike and had the same problem, tried different saddles and suffered till I saw a thread here about rotating the hips/pelvis forward. I focused on that for a few rides and it made all the difference in the world. Can spend hours on the original saddle now without it killing me. I'd link the thread but don't think I have enough posts.

Saddle comfort relies on a number of things some of which have little to do with the actual model and brand of saddle, the first thing and most important thing is fit. A seatpost too high or low a saddle at the wrong angle or setback/forward and poor hand positioning can cause a great deal of problems that have not to do with the actual saddle itself. Once you have that sorted out then it is figure out the correct width for your sit bones too narrow or wide and that saddle won't give you support. If you go too wide you might not be able to pedal right as it will rub and chafe. Then you start getting into length and cut outs and things like that. However you need to adjust and ride the current saddle first before looking at new saddles going out and saying new saddle right away does you no good because you cannot really give solid feedback on what your butt doesn't like about that current saddle. When I talk with clients and they say "that saddle is uncomfortable" (sometimes after just looking at it for a second or two) I always say "there is little you can tell me about that saddle other than what it says on it" because until your butt gets used to it a little and it is better adjusted for you, there is nothing to go on unless you have ridden that saddle before.

Also keep in mind as you get more upright you will put more pressure on the whole buttox so you may need to go wider in certain circumstances as you sit bones are moving to a different position as you go up.

Personally my butt likes the Brooks Cambium C17 Carved but I have wider sit bones (closer to a 168 or something like that, I cannot remember it has been a while since measurement) and for longer rides I typically will wear bib shorts which have padding. However this may not translate to all. I know plenty of folks who also swear by the cambiums and other folks who hate them dearly (and part of that could be adjustment or just be a wrong saddle which is possible)

I would talk to your local fitter or see if your shop offers fitting services or knows someone who can (which may be hard under COVID) also enjoy the bike the Sirrus X 5.0 is a nice hybrid and if I didn't already had a parts hybrid filling a similar purpose and the plan for a flat-bar gravel bike down the pike it would be on the list.

A bike shop can measure the span between your ‘sit bones’ and recommend appropriate saddles. Selle dealers will allow you to trial ride their saddles for I believe a week until you find the right one.
