I definitely feel & know that this is NOT the right saddle for me on this bike, and it will be changed once I acquire another black Brooks B17. However, if I had different handlebars on this bike I could likely use this saddle, so again....boils down to handlebars. Interesting topic. Interested to see what others say.
