The CSU is a user-friendly step up to compliment our CMG. Featuring a thumbtail and some of the concave from the CMG, the CSU feels connected in bigger more powerful surf and still allows for open face carves and snaps when you want to loosen things up. The CSU is great for novice surfers as a first step up, all the way up to experts wanting a more shortboard feel from their step up. The CSU should be ordered 2-6 inches longer than your shortboard. Sizes range from 6'0-6'6
