Upgrade to Specialized's Phenom Expert Saddle and charge hard on all your off-road rides. Its generously padded nose lets you scoot forward to scale steep grades, while the rounded tail lets you slide off the back on descents and scuff guards ward off damage in case you get a little too rowdy. For excellent comfort and support, the Phenom boasts Specialized's Body Geometry ergonomics. You also get a vibration-damping carbon-reinforced shell, a weather-resistant top and lightweight hollow titanium rails. And, it's available in two widths for a perfect fit.
