I've been riding the traditional Arione for several years and decided to give the Evo model a try because some friends told me they like pressure relief channels. I rode my Arione Evo for about 600 miles and couldn't feel any positive difference. The saddle edges are sharper and more pronounced, and I sometimes noticed them rubbing the inside of my thighs while riding in an aggressive position. I eventually switched back to my old Arione felt an improvement in comfort immediately. On a positive note, Fizik's actual weights always match their claimed weights. My Arione Evo weighs 210g on the scale, just as the marketing info suggests. Overall, this isn't a bad saddle-just not the right saddle for me.
Great Saddle! I have both the R3 and the R1 of this saddle. I really like them both. They are built for competitive cyclists, so there is not a ton of padding. However, for the competitive cyclist, they are both comfortable.
