Rail Material: K:ium Alloy
Weight: 210 g.
The Fizik Antares 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 K:ium 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). Antares Versus X is for The Chameleon: Medium Spine. If you have an intermediate degree of spinal flexibility (approximately 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 chameleon. Your degree of spinal flexibility helps you so far, before you need to rotate your pelvis slightly to achieve fully the performance position. You will benefit from the increased width and slight curvature of the Antares shape. ICS compatible.
