My issue has been perineal pressure. 24 hours of numbness in the nether region after a 400 km brevet was a bit concerning, and made me glad that I already had three children and was not planning on having any more. I had been riding on a Fizzik Arrone. It is a great saddle for anything up to a century for me. I switched to a Selle Anatomica before my first 600 km last year and had great success with no pain. I will say this. In less than 3000 miles of riding I have nearly extended the tensioning bolt to its limit. The seat is comfortable, but I think there is a loss of energy transfer because of the movement of the anatomica. It is just not as stable of a platform. Does that make sense? I have ridden a Brooks Team Pro in the past. I still have it, but it has cracked at the rear rivets. I thought about getting a new one, but then decided to try the Anatomica.
Any opinions on the loss of efficiency?
