Selle Specialized Power Comp 155mm Noir

Where the Power Comp 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.
