If you don’t want a part of your body to get sore, then that part shouldn’t be pushing against something that doesn’t move along with it. That’s the thinking behind the vabsRider bicycle saddle, the two sides of which pivot in time with your pedaling.
Not sure but it sounds like your old one was maybe Brooks b67?
It also sounds like the new saddle didn’t fit you. Your sit bones should match the width of the saddle.
Oh, those look really cool… the one I replaced on my bike was a Schwinn comfort saddle that you can get at Walmart for $40.
Less expensive isn’t inherently bad, as long as it fits and holds up those are the big ones.
