Braided carbon fiber rails underneath this saddle are obvious, and they offer a nice weight savings, that's not what this saddle is really about. It's about the carbon fiber shell. It's actually two layers of carbon-fiber sandwiching a thin layer of foam. This provides great support while allowing appreciable flex at the edges. Along with the WingFlex technology, this means that the sides of the saddle will move with your legs while the top will remain rigid. A true racing saddle. Color: Black.
