Yellow Deck, Blue Deck, Red Deck. All with Black Rails and White Slick

hey, im very interested in buying this in the 42". just wondering what is a "rocker" and what does each type of rocker do? thanks

Hey Adam The rocker is the curve through the length of the board. If you put the board on the ground slick down the board will rock if you tap it on the nose or tail. Dead flat means it will lie flat with the gradient shaped into the nose the only thing coming off the ground. It will not "rock" This is fast and holds in well, More for the advanced rider. Little bit of nose rocker means it will have a slight lift off the ground from around the first foot or so from the nose. Less Likely to Nosedive and easier to turn. For the Intermediate Rider. Quite a lot of rocker means both the nose and tail will be lifting off the ground if it's lying on the ground. Only the middle of the board will be touching the ground. Not likely to nosedive and easy to turn but not very fast or responsive. For the Beginner rider Touch of reverse rocker means the nose and tail will be touching the ground and there will be a slight lift off the ground in the middle of the board. This board is super fast and responsive but easy to catch rails and nosedive. For the Advance rider or pro Most boards are Dead Flat. Most Pro's ride Reverse rocker. Hope this answers your questions.
