The Selle Italia SLR Carbonio saddle is a lightweight saddle of refined style. It is perfect for road or mountain use and an elegant choice for the show bike. The SLR carbonio utilizes the best properties of carbon--extraordinary lightness and high strength.
I really like this saddle. Found it for about $100 on a different site last fall. Didnt expect to like a saddle this small and minimally padded. Want a second but dont want to spend near full price. I am over 170 lbs and have broken several Ti railed saddles, almost a full season and so far so good. The carbon rails are thick but fit fine in my Giants ISP seat-mast clamp.
Except for the carbon rails, its identical to the ti SLR. Its a bit lighter. The padding seems the same. Despite being carbon, I was surprised at the sturdiness of the rails. And thats where the 4 out of 5 rating comes in. The rails are almost twice as thick as their ti counterpart. It was not compatible with my USE carbon seatpost. But was compatible with my Easton carbon seatpost.
