The Phenom Comp was designed for comfort and strength over long days on the road or trail. It features a carbon-reinforced shell with outer edges that 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 Expert it has our medium density Level 2 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.
