PN 2.1It features the same 40 series foam and gel padding as the PN 1. 1, but features custom laser etched graphics, upgraded chromoly rails, and a rear transition hook for easy racking and storage. Like the other Performance Narrow saddles, the PN 2. 1 is 110mm wide, offering superb thigh and hamstring clearance. This allows for more rider body movement around the seat, and is great for diving into fast corners.
