Rail Material: Kium Alloy
Weight: 250 g.
The Fizik Arione Versus X saddle features a 20mm deep relief channel down the middle allowing greater pressure relief while maintaining the stiffness and durability of a solid base saddle. The outer shell is nylon carbon reinforced with a black Microtex cover. The Kium rails are made with a special alloy with a high strength-to-weight ratio and excellent vibration damping (8% weight reduction compared to solid titanium). Arione VS X is for The Snake: Flexible Spine. If you are very spinally flexible (far less than 90 degrees between your straight legs and your back when bending over as far as you can, keeping your legs straight a shoulders' width apart), you are a Snake. You achieve the performance position using your spinal flexibility alone, not rotating your pelvis at all. You will like the flat, narrow and long shape of the Arione. ICS compatible.
