Most boards measure 84 to 150 centimetres (33 to 59 in) long while the width varies from 22.8 to 25.4 centimetres (9.0 to 10.0 in). There are several shapes of longboards, such as pintails, flat-nose riders, drop through decks, drop decks and boards with the same shape of a standard skateboard. Pintails permit looser trucks and larger wheels which are better suited for carving or a "smooth" feel, whereas drop decks and drop throughs allow the rider to be closer to the ground, hence a lower center of gravity which increases stability and allows these boards to support more high speed downhill riding disciplines. Mid-length boards, 94 to 127 centimetres (37 to 50 in) are the most versatile. Their greater weight and bulk makes them less suitable for many skateboarding tricks, but contributes to a fluid motion by providing more momentum. The longboard's design allows for big turns or quick short carves similar to the motions of surfers or snowboarders. Longboards have 3 axes: the tail axis (running from tail to tail), the central axis (running straight down through the center of the board), and the short axis (running from the width of the board and perpendicular to the tail axis).
The previous record for the longest distance traveled on a longboard was set by David Cornthwaite in 2006 when he skated 3,638.26 miles (5,855.21 km) from Perth to Brisbane across Australia. This record has since been broken by Rob Thomas of New Zealand, who skated 7,555 miles (12,159 km). The land speed record on a longboard was set in 2012, when Mischo Erban reached a speed of 129.94 km/h (80.741 mph).
Equipment & protection
The ‘helmet culture’ is more prevalent in longboarding than in skateboarding. Most riders wear protective equipment in all disciplines, and nearly all professionals wear a helmet and gloves. Longboard protective equipment is similar to standard skateboard equipment, with the exception of slide gloves. Most longboarders wear slide gloves and helmets, as these are considered the bare minimum for protection. Additional protection includes: leathers, wrist guards, knee pads, elbow pads and sometimes spine protectors and padded shorts. Many professional longboarding teams and riders are required to wear and advocate all aspects of protection. In the sliding and downhill disciplines, riders wear "slide gloves" which are specialized gloves made out of a strong materials such as leather and synthetic fabrics, and have large discs called "pucks" attached to the palms. These are attached to protect the hands as the rider uses them to pivot during slides along the ground. The pucks are usually made of synthetic polymers: delrin, UHMW, or corian.
Longboards are skateboards in terms of parts and general construction. However, the parts generally have different dimensions and the wheels are most likely a lot softer. Some, however, have relatively hard wheels for sliding, which makes longboards feel quite different than the ubiquitous skateboard.
Longboard decks are typically made from plywood anywhere from two to eleven layers of usually 2 millimetres (0.079 in) in thickness, composed of birch, bamboo, maple, koa, or oak wood . Longboards are commercially available in a variety of shapes and sizes. Each variety has certain advantages and disadvantages, which come into play depending on the technique or personal preferences of the rider.
Decks intended for riding downhill are typically stiff and have a wheelbase of around 30"-28" . Designers and manufacturers aim to make these boards as stiff and light as possible. The primary three designs of downhill boards are "drop decks", "top mounts" and "drop throughs". Each design has its own advantages.
The "drop deck" has a lowered foot platform that sits below the height of the trucks, as a result, there is a lower center of gravity which adds to stability but gives you less traction and maneuverability. Wooden drop decks with concave have foot pockets by the drops. However, some carbon boards are able feature concave by the drops instead of foot pockets giving you more leverage in your turn.
The "drop through" design has cutouts that allow the baseplate of the truck to protrude through the board, thus lowering the deck and providing more stability. In addition to this, drop through decks decrease grip, as the deck is closer to the axle and Moment arm of the wheel. There is also less leverage on the truck, which makes turning negligibly more difficult.
"Top mount" boards are the simplest design of the three. There are no dramatic bends aside from the foot concave. The board sits on top of the trucks as it would in a street skateboard. Advantages to this design include increased grip and ease of turning; disadvantages include a high center of gravity, which could contribute to a lack of stability.
There are many variations of the aforementioned designs, including a "double-drop" board, which incorporates both a drop through and drop down pattern. These are preferable for "freeride" as they are extremely low to the ground, which allows for ease of sliding. Footspace is important because there must be enough room on the board for the rider to form an aerodynamic "tuck". Downhill boards are made as stiff as possible to minimize the amount of energy stored in the deck in order to ameliorate the creation of "speed wobbles".
Some boards are designed to be flexible. Flexible boards are usually intended for lower speed riding because when going faster, a flexible board can have torsional flex which is one cause of speed wobbles.
Longboard decks can be shaped in such a way that they bow up or down along the length of the board. They can also have a downward bend along the width of the board. Concave boards, which bend upward on the sides, give the rider more friction for their toe and heel, thus giving them more control. Longboards, typically boards designed for downhill and or freeride, can also have W concave which is concave with a ridge in the middle forming the "W" shape. W concave is helpful in a slide or corner by giving your feet extra grip so that your feet (especially back foot) stays on the board. A camber board is a gradual upward arch along the length of the board. This sets the center of the board above the truck mounts. This is often used on flexible boards to prevent the board from sagging when it is being ridden. A "rocker" shape is the opposite of camber, which sets the center of the board below the truck mounts when it is being ridden. This lets the rider more easily perform tricks like sliding by locking your feet into the board.
The pintail shape is used to prevent the wheel from coming in contact with the board (called "wheelbite") while still providing ample footspace. Pintails are most commonly used with top mounted trucks.
Drop-Through boards, not to be confused with a double drop deck, have a cutout in the deck, allowing the baseplates of the trucks to be mounted through the deck. The lowered platform allows for greater stability at high speeds. Some examples of drop-through decks are the Landyachtz Drop speed, Jaseboards Drop, Rayne Vendetta, Bustin Maestro, Original freeride 41, the Sector 9 motha Star and the Loaded Tan Tien.
These kind of longboards include wheel cutouts which provide room for the wheels to turn at sharper angles while avoiding wheelbite. Hybrids also tend to be shorter than other longboards, which allows the rider to complete the same tricks as on a standard skateboard. A downside of hybrid longboards is the potential for "shoebite" which happens when the rider's shoe rubs the wheel, slowing or abruptly stopping the rider.
A most common deck shape, these have a somewhat similar shape to normal skateboards, in that they have a "kick-tail" on the back. The main difference is it has trucks that are higher than standard skateboard truck also the wheels may be larger and are much softer than standard skateboard wheels. The bushings are much more flexible, giving the rider the ability to turn (carve) and maneuver more efficiently.
Trucks are the metal turning mechanism that attach the longboard wheels to the deck. They come in a wide range of styles, with wider trucks meaning a wider turning circle. They use the motion of the rider's feet and body to turn the board by pivoting a joint in the middle of the truck. There are generally two types of trucks used on longboards: reverse kingpin trucks and conventional skateboard trucks (vertical kingpin). Conventional skateboard trucks have the axle on the outer side (towards the nose and tail) of the kingpin, whereas reverse kingpin trucks have the axle on the inner side (towards the center of the board) of the kingpin.
Popular conventional skateboard trucks include Independent and Tracker. Popular reverse kingpin trucks include Randal and Paris. Reverse kingpin trucks were created with longboarding in mind. While they are usually considered to have more grip and stability (two important things in the downhill discipline), conventional trucks have a very different feel that is often preferred by many longboarders.
Hanger width can greatly influence the turning characteristics of a truck. A wider hanger is thought to be more stable (turn less quickly). This is because the board generally has less leverage over the hanger, the wheels have a further distance to travel to get to an angle, and more board lean is lost due to bushing compression.
The angle of the baseplate can also greatly influence the turning and stability of a truck. As a general rule, as the degree gets smaller, the truck will be more stable, but turn less (its turn essentially becomes more vertically oriented rather than horizontally oriented). For example, trucks with 44 degree baseplates will generally be more stable (turn less) than trucks with 50 degree baseplates.
Bushings are perhaps the easiest things to change on a truck in order to change the feel of how it turns. Bushings are usually made of a polyurethane material, and come in varying shapes and durometers (hardness). Two of the most standard bushing shapes include barrels and cones. Barrels, having a larger shape, are often thought to have more stability and rebound whereas cones, having a more narrow shape, allow for more turn and less rebound. The durometer of the bushing also greatly influences its characteristics. a harder bushing (such as a bushing with a rating around 97A) will be much harder to turn on than a softer bushing (something around 78A). The type of washers used with the bushing can also greatly affect the bushing's characteristics. While it depends on the size of the washer, generally a cupped washer will be the most restrictive on a bushing, a flat washer will be neutral, and a flipped cup washer will be the least restrictive. Another aspect of the longboard that has an influence on bushing performance is the bushing seat on the truck. The bushing seat is the area on the hangar where the bushing makes contact. This area often has a rim to cup the edge of the bushing, adding a small amount of restriction as the bushing deforms through a turn. Some trucks have very loose or even non-existent bushing seats, whereas others have very restrictive bushing seats, greatly reducing bushing deformation. More restrictive bushing seats generally found on trucks designed with faster riding in mind as they offer more stability and lean.
Riser pads increase the distance between the wheels on a longboard and the deck in order to prevent wheel bite (when the deck scrapes the wheels, causing the wheels to stop turning). They also reduce the strain on the deck from the trucks being directly in contact with it. Riser pads are normally made of plastic. Shock pads, which are more rubbery than riser pads, serve the same function only with more emphasis on reducing strain and less on increasing the distance between the wheels and deck. Riser pads also come angled which can make the board turn more or less. Angled risers are usually used by LDP's(Long Distance Pumper) to help aid the rider in pumping (propelling the board with turns)
Bearings connect the wheel to turn smoothly. Bearings can be made of many materials, including steel (which is most prevalent), titanium, or ceramics. Ceramic bearings are the most expensive. Bearings are usually rated in the ABEC scale. The ratings run from 1-9, using only odd numbers. The higher the rating, the more precise tolerances the bearing has been machined to. However, ABEC rating is not compulsory and not all bearings use ABEC ratings. Some companies will use other methods to describe the bearings' resistance and durability. Optionally, longboarders add bearing spacers between the bearings in the wheels. This allows for the axle nut to be tightened all the way down eliminating the high frequency wobbles and increasing the lifetime of the bearings.
Almost all longboard wheels are made from urethane. The performance of longboard wheels is determined by five characteristics: height, lip shape, contact patch, durometer, and hub setting. Typical longboard wheels range from 65 to 107 millimetres (2.6 to 4.2 in). A taller wheel will have slower acceleration but a faster rolling speed. Smaller wheels have the opposite effect. The durometer of a wheel is how hard the urethane is. A softer wheel will be ultimately slower than a harder wheel on smooth surface. When the road surface gets rougher a softer wheel provides a smoother, faster ride. The fastest duro for the normal road is around 80a. Softer wheels have more grip than harder wheels on any surface. The contact patch of a wheel is the width of the section of the wheel that makes contact with the road. Generally, the wider the wheel, the more traction it will have. Wheels can be anywhere from 50 to 100 millimetres (2.0 to 3.9 in) in width, but most commonly between 60 and 70 millimetres (2.4–2.8 in). The shape of the lip has a noticeable effect on traction. Rounded lips are made to break loose into a slide and square lips are made to grip. Square lipped wheels do break loose but the slide is not as smooth as that of a round lipped wheel. A wheel hub (or core) is the plastic (or sometimes aluminum) center of a wheel that holds the bearings. The position of the hub affects the properties of the wheel.The Longboard is faster than Skate, but a variation of greater speed occurs Longboards properly prepared
The hubs in centerset wheels are set equidistant from each lip of the wheel. Centerset wheels tend to have the most grip, because they have large inner lips, and it is the inner lip of a longboard wheel that grips the most. Some longboarders prefer centerset wheels for sliding because they wear more evenly and when they become coned they can be flipped and still have the same feel. Centerset wheels are more difficult to break loose than other wheels, and more speed is lost during the slide, but the slide is more controlled because of the grip the wheel has.
Side-set have wheel hubs set flush with the inside edge of the wheel. Side-set wheels offer a smooth transition from grip to slide, the slide typically being longer than that of any other wheel. This type of wheel has by far the fastest and most uneven wear because the rider's weight is on the very inside of the wheel. Freeriding is typically the discipline that this particular kind of wheel is used for.
The hub of an offset wheel is between the center and the inside edge of the wheel. Offset wheels provide less grip than a centerset wheel, but more than a side-set wheel. Similarly, they break loose more easily than a centerset wheel, but less easily than a side-set wheel. These wheels usually feature square edges for more traction around corners or in carves. Off-set wheels are the most common wheel, typically used and designed for Downhill but they are used for all the other disciplines as well.
A pair of slide gloves is an important piece of equipment for longboarding. Slide gloves are for control as much as for safety. They allow the rider to touch the road and lean on his or her hand(s) to slide to a stop, to pre-drift into a corner, to touch the road to regain balance if balance is lost, and to protect the hands and support the rider's body during a fall. There are many style moves that also can slow the rider down that can be used called slides. There are various slides such as the K9, pendulum, coleman, and 1 footed stalefish. These type of gloves could be home made with just a thick plastic layer, and a glove.
The Big Stick is a large pole or stick, usually with rubber or something similar on the end. This can be used to propel the rider far distances without the use of the riders legs, and is primarily a form of locomotion derived by the riders arms. The rubber end sometimes resembles wheels however they can not turn as they are fastened. Being in a wheel shape allows even wear as you can losen, turn and fasten them again instead of having to replace the rubber. The Big Stick was invented by Steve McBride of Kahuna Creations.
