The Power Comp saddle features a stiff, carbon-reinforced shell & a Body Geometry design that caters to both men & women. 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 & pressure mapping, & featuring our medium-grade Level II PU padding, the extra wide & elongated Body Geometry channel & proper sit bone support provides all-day comfort.
