The Phenom Comp was designed for comfort and durability during long road or mountain bike rides. It features a reinforced carbon shell with outer edges that conform to your body for an almost custom fit. Unlike the Expert model, this version has durable Cr-Mo rails for added peace of mind. Like the Pro and Expert models, it includes our level II medium-density padding for extra support and comfort. At the back, you'll find the rounded shape unique to the Phenom with its anti-chafing coating, and along the entire saddle, a perfect construction that offers the ideal balance of stiffness and flexibility.
