Since you remind me that it was one side specifically -- OP could also try adjusting the saddle
straightness. Counterintuitively, pointing the nose of the saddle
toward the side that chafes could reduce the contact between the inner thigh and the saddle.
Here again, try very small changes at a time. (Maybe the saddle wasn't straight to begin with, and that was the source of the problem all along.)
