I had an Adamo, don’t remember the model. I used it for less than three months before giving it to the local bike co-op. After a twelve day tour I had such a painful rash on the inside of my thighs I had to tip the saddle way down in the front just to keep riding. I’ve read this is a common complaint. On the plus side there is zero pressure on the soft tender places. I see a number of triathletes using them on their TT bikes. You sit far forward with half or more of the rear section there just to satisfy UCI rules.
