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. Patented Body Geometry Design is lab tested to assure blood flow to sensitive arteries. Carbon-reinforced shell with flexible Adaptive Edge technology adapts to your body for a custom fit and all-day comfort. Low friction panels on the nose and tail improve pedaling efficiency and mobility while moving aon and offa the saddle. Light and super-durable, hollow Cr-Mo rails. Lightweight and supportive PU foam for increased comfort on longer rides. Level 2 padding: Medium density foam for bike feel with additional cushioning.
