The Kool Stop Campi Super Record 2011 brake pads are a quality replacement brake pad that is also friendly to the wallet. They have the void on the back for use with the 2011 and newer 11-speed skeleton brakes that allow for the brake pad retention spring/clip located on the pad holder. They are also backward compatible with 2000 and newer Campagnolo® and Zero Gravity® brakes so these will basically work for any Campagnolo brakes made after 1999.
The black compound is Kool Stop's standard compound which is great for all weather conditions, but designed for dry condition riding. Sold as a pair so buy 2 pair for one bike.
