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 medium-grade Level 2 PU padding, the extra wide and elongated Body Geometry channel and proper sit bone support provides all-day comfort.
