I am one happy owner of the Fizik Terra Argo X3 Saddle. I bought this saddle with the intention of using it for a mixture of Gravel & Road riding, albeit for my Gravel Bike. As for myself, this saddle has made a huge difference in my daily riding. Comfort, stability and performance come to mind without the feeling of an over cushioned seat. This saddle is firm, but compliant and does an excellent job of dampening vibration when riding on washboard gravel roads. I have 500 miles plus on this saddle and haven't had one saddle sore yet!! Most of my rides consist of 2-4 hours time in the saddle. Please note that there are two different sizes in this saddle ... a 150mm and 160mm width. I chose the 150mm for my style of riding which is training, racing, and time in the drops. I did consult with the Fizik directly about the sizing, and they suggested the 150 mm for my style of riding (Racing) which coincides with my physical measurements. As a result, I ended up purchasing the same saddle for my custom gravel bike build project. Lastly, this saddle flat out work! I have found it to deliver in every aspect of the market claim made by Fizik. It's hard for me to imagine if there is a better saddle out there. For a greater technical description feel free to go Fizik's website.
Hands down this is the most comfortable saddle that I've ridden to date. No saddle sores, or chaffing. Helps with the dampening.. Helps with stability and balance while giving a solid plant when seated. My bum definitely approves! :)
