Regarding saddles, as elsewhere, the more things change, the more they stay the same.
From Jerome K Jerome's "Three Men on the Bummel" via project Gutenberg:
"...this is an imperfect world of joy and sorrow mingled. There may be a better land where bicycle saddles are made out of rainbow, stuffed with cloud; in this world the simplest thing is to get used to something hard. There was that saddle you bought in Birmingham; it was divided in the middle, and looked like a pair of kidneys.”
He said: “You mean that one constructed on anatomical principles.”
“Very likely,” I replied. ... I only know that I tried it myself, and that to a man who wore flesh it was agony. Every time you went over a stone or a rut it nipped you; it was like riding on an irritable lobster.”
Yet the Brooks remains - and remains essentially unchanged. And it doesn't look like a pair of kidneys.
The B67 works really well on a folder, it should be noted.
