Fizik Aliante Versus Saddle Braided Carbon Rails 2013: Super comfortable Aliante saddle with Versus pressure relief channel is now offered in a even lighter saddle thanks to rails made out of carbon braided the perfect combination of comfort & lightness. Aliante Versus Saddles incorporate a pressure relief area into the most popular Spine Concept shape. Fizik believe comfort is achieved by optimising the seating surface area & that full cutout designs decrease seating surface & support. Versus saddles have the same surface area as the corresponding solid surface saddles. Versus saddles us the same base as the currant road saddles to maintain structural integrity. Saddles with cutouts have a weaker base structure, & begin to flex & sag immediately in use. Versus saddles use the optimum ergonomic channel shape to ensure pressure relief & support without involving the sharp edges common in cut-out saddles. Shell: Nylon carbon reinforced Padding: Low density with relief channel Rail: Braided Carbon Weight: 219 gr
