The Phenom Comp 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, along with our Adaptive Edge base that allows the outer edge to conform to your body for a near-custom fit. This version, unlike the Expert, has durable Cr-Mo rails for peace of mind, and like the Pro & Expert, 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.
