VS saddles feature a 7mm channel design that allows for greater pressure relief, whilst maintaining the stiffness & durability of a solid-base saddle. -Solid base ensures saddle’s structural integrity is unaffected. -No reduction in saddle’s surface area, therefore no subsequent increase in pressure. -Relief channel spans the length of the saddle, allowing the rider freedom to move along it. -Edge of relief channel is a gradual change in the foam mould leaving no sharp edges that might cause pressure points. Arione VS is for The Snake: Flexible Spine. If you are very spinally flexible (far less than 90 degrees between your straight legs & 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 & long shape of the Arione.
