I am 56 years old, and cycle 3 times a week for a total of about 125 km per week and elevation of about 2000 Meters a week. As a "more mature" rider, discomfort from the saddle has been a real issue, even with very padded shorts. I could not go more then 1 1/2 hrs without feeling real discomfort and even pain. I decided I would try the Selle Anatomica Leather saddle and I am very, very pleased. I can now ride for 3 hours and although I can't say "I don't feel the saddle", but it is SO much more comfortable then any other saddle I have ever been on. I am VERY happy I bought the X series and will definitely return when I am ready for an "upgrade!" 5 stars! As an aside, I live in Israel and was amazed at the speed and efficiency of the shipping department. Quite impressive!
