The Phenom Expert is a mountain bike saddle that's designed for comfort and strength over long days on the trail. It features a carbon-reinforced construction at the shell with outer-edges that conform to your body for a near-custom fit. This version, unlike the Pro, has rugged titanium rails for lightweight durability, and like the Pro, it has our medium density, Level Two Padding for ample support and comfort. Likewise, at the tail, you'll find the Phenom hallmarks of a rounded, anti-snag design, and throughout the saddle, an expertly tuned construction that provides the ideal degree of both stiffness and efficiency.
