You are so right, in the matters of the butt.
At first, I did not adjust the position of the saddle and just went for a long ride on the new bike.
After a while, I had a painful ass which took some time to go away.
The next time, I carefully checked how I could adjust the position of the saddle and found that I could turn the seat post 180 degrees to turn it around so that the saddle can be positioned as near to the handlebars as possible.
I had to take out the saddle, turn it around and screw it on again as it was facing backwards.
But when I tried a short ride, it just felt so much more comfortable than the almost crouching position of the new bike without adjustment. Now I felt like my weight was more on the "meat" of the butt rather than the two lower bones under my butt, if you get what I mean.
This improved position helped but it did not completely removed the soreness after a long ride.
So I had two options: 1) change the saddle to something more comfortable or 2) buy padded pants.
As the padded pants were not cheap, I decided to look at another saddle and found what is a godsend gift for relieving painful butts, a Royal Gel saddle from MBShop.... Selle Royal brand. This was easily the most valuable buy for my bike and it did not cost too much, surprisingly as it was made in Italy.
Now I could enjoy long rides comfortably.
will definitely need to relook the saddle issue .. need to get some tools to open them up
