Specialized new Power Pro Elaston saddle is in a category all its own. To start, they  focused on ensuring that it's very lightweight, which led to the design's inclusion of a stiff, FACT carbon shell with durable titanium rails. Meanwhile, the Body Geometry design was developed to cater to both men and women alike, and this helps deliver superior performance in all sitting positions—especially in aggressive ones. They have proven this extensively through blood flow testing and pressure mapping, and this process inspired them to create the lightest level of padding available. And this is where the Elaston differs from its Power brethren.
