The Fi'zi:k Arione Versus MG Bike Saddle combines fi'zi:k's Spine Concept and a central relief channel. The Arione is longer than any other saddle, flat from nose to tail, with a narrow nose so you can move around to find your power spot. The Arione Versus MG adds the Comfort Channel along the length of the saddle. Additionally, it features a carbon reinforced Nylon shell for support with optimized stiffness to-weight construction - with Wing Flex technology which enables flexibility where your thighs meet the saddle - and a manganese rail for light weight and strength. If you've used Fi'z:k's Spine Concept and have found which animal you identify with based on the flexibility of your spine, the Arione Versus falls into the Snake category.
