The Power Comp saddle features a stiff, carbon-reinforced shell and a Body Geometry design that caters to all riders. Where it differs, however, is a matter of rails-Cr-Mo rails to be exact. This means that you sacrifice some weight savings, but otherwise, you receive the same superior performance in all seating positions-especially aggressive ones. Proven through blood flow testing and pressure mapping, and featuring our medium-grade Level 2 PU padding, the extra wide and elongated Body Geometry channel and proper sit bone support provides all-day comfort. Patented Body Geometry design is lab-tested for both men and women to assure blood flow to sensitive arteries. Stiff, carbon-reinforced shell for longevity and all-day riding efficiency. Lightweight and supportive PU padding for comfort and support on longer rides. Durable hollow Cr-Mo rails. Tough, lightweight, and water-resistant cover. Level 2 padding: Medium density foam for bike feel with additional cushioning. SWAT(TM)-compatible mounts molded into the saddle base allow for sleek and integrated storage solutions.
