Fizik Aliante Versus Saddle with K:IUM Rails 2013: Super comfortable Aliante saddle with Versus pressure relieft channel. Aliante Versus Saddles incorporate a pressure relief area into the most popular Spine Concept shapes. 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. Cover: Black / black glossy microtex Shell: Nylon carbon reinforced Padding: Low density with relief channel Rail: K:ium Weight: 259 gr Dimensions: 265 x 142 mm
