We left all the forward volume our original Chem Zen had in this model. With the Chem Zenagain we removed the retro beak, added more nose and tail rocker while widening the tail block. This allows the board to fit in the curve of the wave easier and keeps the tail loose. You can choose the Chem Zenagain with or without 4 channels. The 4 channels give the board a bit more bite on the wave, but not too much where you won’t be able to turn it. The Chem Zenagain is a modern version of a proven design that has been a staple in our line up since 2010.
