I went into my bike shop after confirming that yes, indeed, this puppy gets uncomfortable by 10 miles. I tried to analyze my riding and figured that with less gut I'm bending over a bit more ... but basically there seemed to be more weight and pressure in the wrong places. I was even pondering the fact that thanks to doing my cattle-prod duties (I've been instigating some rides iwth a couple of buddies ... ) I've done about five times as much fast riding as ever before in any given season and ... maybe I was learning to... and leaning to... oh, road bike position? (I have a fast hybrid.)
welp, that seed just might have been planted ... we'll see...
... but I went in and my bike guru says "let's see." And he asks "what's that lump on your seat?"
And now that he has sawed off that screw, my seats not.... ahem... screwed up so the problem may be solved - going to ride hard tomorro and find out
I could have spent a chunk of change on a seat... so often dealing ith an LBS *saves* money.
