This is my third Selle Italia, but the first SLR. I bought it to replace another Italian brand that was similar in design, a bit lighter, but caused significant muscular pain from the contact area all the way down the ham string. The first ride on this saddle was the Alpen Brevet in Switzerland. After 11 hours in the saddle, I not only felt exhilarated from having finished, but also physically great. This is a perfect match to my Specialized Tarmac. I recommend it with no reservation.
