Just another link to a different seat.
Didn't see anything aftermarket at the bike show last weekend or in any of my internet searchs.
My last SO whined a little about being uncomfortable at times as well. She mentioned trading the bike in to make her happy. I compromised and traded her in. Now I'm happy.
Let me know if you find anything.
