On a camber deck, there will be much more flex because of the higher center of gravity. Rocker decks have a low center of gravity, and many riders find the dipped shape more comfortable to stand on and feel 'locked-in' on, giving confidence more rapidly. The minimal flex makes rocker boards a good choice for stability and predictability when riding. A camber can give a nice springy 'pump' when carving, but can be a little more complex when handling due to this nothing too difficult though.
The majority of longboard decks are flat-have no camber or rocker, though some cruisers and longboards feature camber-style decks. The longitudinal curve of the deck also plays an important role. Decks with a raised center are known as camber and low decks are rockers. With positive camber there will be a lot more flex due to the higher center of gravity. The rocker ones have a low center of gravity, much more stable in downhill and at high speeds. There are 2 types of truck mounting on the longboard: the top mount and drop through.
Top mount means that the truck is hooked directly under the board and therefore will be more responsive to commands.
While drop through trucks have their baseplate attached to the top of the deck, so you will have a low center of gravity for more stability. Although their purpose is similar, longboard trucks are extremely different from skateboard trucks, as they are obviously wider to adapt to the difference in size most are mm or mm. A longboard truck is known as a reverse kingpin, because the axle is located on the other side of the kingpin compared to a standard truck, in order to have a greater turning angle and more maneuverability.
Wheelbase should be a top factor in determining which deck you want to buy. The wheelbase of a deck contributes to everything about the board. From the way it turns in to the way it handles speed, wheelbase is incredibly important.
This is because the wheelbase determines the overall riding experience. The longer the wheelbase, the bigger the arch it takes to turn a skateboard with the same amount of lean.
In downhill and freeride applications, some people prefer shorter wheelbases for more grip and longer wheelbases for more drift. This is because shorter wheelbases allow the rider to focus more weight directly over the trucks. Concave on a longboard is perhaps the most important aspect there is. It is the concave that provides the rider the foothold they need to perform at the top of their game. There are six main types of concaves as seen above.
These images are slightly exaggerated profiles of skateboard decks from the perspective of looking head on and straight down the length of the board. Radial - Radial is probably the most common form of concave. If you were to draw a giant circle and then slice part of it out, you could use the small curve you cut for as a template for radial concave. Progressive - Like Radial, progressive forms a continuous arch. However, progressive concave gets progressively steeper wow, is that how they named it?
Convex - Convex is the opposite of concave. Convex is when the board arches up instead of inward. This is the least common type of concave as it allows for minimal leverage over the rails. Asymmetric - Asymmetric concave is for those who want a different feel during their toeside and heelside turns.
Because riders can typically get more leverage over their heelside turns, asymmetric attempts to compensate for all those little toes. This keeps feet flatter and in a more natural position, yet still allows for that needed leverage at the toes and heels. No Concave - We don't have a picture of this guy because no concave is just flat and not hard to imagine. However, no concave is common in longboards, especially pintails and other cruisers, so it is definitely worth mentioning.
Camber and Rocker are opposites of each other. This usually allows more energy to be stored in the board as the pan will be designed to flex down flat when the rider is standing on it. Like Rocker, Camber can put the rider in a precarious position at high speed.
A flexy board tends to be less stable and a stiff board with camber puts the rider above the trucks high center of gravity. Both of these makes the board susceptible to rider errors and thus speed wobbles. The nose or tail of the skateboard that has been bent upwards to allow for more leverage over the rest of the deck. This feature is commonly known as a kicktail upturned tail or kicks referring to both the nose and the tail. The kicktail or kicks can allow the rider to ollie, manual, etc.
This opens the door to a plethora of various other tricks. There are several basic types of defining longboard truck mountings. Different mountings change the way the rider puts leverage over the trucks and thus changes the way the rider turns the board. The rider can feel these changes through their feet.
The various types of truck mountings are as follows. Top Mount - Tried and true, a top mount is exactly as it sounds. The trucks mount directly flush to the deck and the deck includes no fancy curvatures to position the trucks.
This gives the rider the most leverage over the trucks as a boarder is standing "on top" of the trucks. Skilled downhill guys like this because it's the most responsive and touchy set up. Newer riders might find a board like this too twitchy. Camber is very common on cruising and carving boards. Rocker is the opposite of camber. Rockered boards bow downward creating an uphill surface for the rider to leverage against and reducing the height of the board off the ground.
Rocker is a popular curvature for freeride and downhill boards. Dropped curvatures create a lowered deck platform with extreme drops in the tip to tail curvature of the board.
These drops often create pockets that are great for locking your feet in for turns or slides. Dropped platforms are lower to the ground, easier to push and more stable at speed. Single Kick and Double Kick boards have either one or two kick tails.
