This is our top 3 high performance model. The outline is a touch wider from nose to tail. The bottom rocker has a harmonic flat entry and finishes with a fair curve in the tail which has a deep single concave with a double inside around the tail area, going to a smooth single for the rest of the board. The board is extreme fast and responsive, it has the right balance for those modern manoeuvres. The Kryptonite as the name suggests "from the Super-man series" it is a very addictive board for the everyday mushy to those perfect glassy days.
