Specialized's Phenom Pro is a World Cup-level off-road saddle. Its generously padded nose lets you scale steep grades, while the rounded tail encourages sliding off the back on descents, and scuff guards ward off damage in case you get a little too rowdy. The Phenom boasts Specialized's renowned Body Geometry ergonomics for all day comfort. You also get a supportive, vibration-damping carbon-reinforced shell, a weather-resistant top and featherweight FACT-carbon rails. And, it's available in three widths for a perfect fit.
