Each skateboard wheel is mounted on its axle via two bearings. With few exceptions, the bearings are the industrial standard "608" size, with a bore of 8 mm (or 10mm depending on the axle), an outer diameter of 22 mm, and a width of 7 mm. These are usually made of steel, though silicon nitride, a high-tech ceramic, is sometimes used. Many skateboard bearings are graded according to the ABEC scale. The scale starts with ABEC1 as the lowest, followed by 3, 5, 7, and 9. It is a common misconception that the higher ABECs are better for skateboarding, as the ABEC rating only measures tolerances, which do not necessarily apply to skateboards. Bearing performance is determined by how well maintained the bearings are. Maintenance on bearings includes periodically cleaning and lubricating them . Bearings that are kept unmaintained have their performance greatly lowered and will soon need to be replaced. Bearing cleaning kits are commonly available on the market. The ABEC rating does not determine the speed or durability of a skateboard bearing. In particular, the ABEC rating says nothing about how well a bearing handles axial (side-to-side) loads, which are severe in most skateboard applications. Many companies do not show the ABEC rating, such as Bones Bearings, which makes bearings specifically for skateboarding, often marketed as "Skate Rated". Each bearing usually contains 7 steel or ceramic bearing balls, although other configurations are used as well.
The DreadXBoards Concave Skateboard has Plastic Deck Injection Molded for excellent durability. It features Urethane Wheels 59mm 78a, aluminum trucks, and Abec 7 Bearings. It is completely assembled and is ready to ride. It is perfect for beginners or experienced riders. It can load up to 185 lbs. It is great for kids and adults. It has an excellent rating of 4 on Amazon.
The board is shaped like a cup in the center, and has whale tails on both ends, designed to make tricks easier to do. The blue stain on the board looks like the picture. It has a semi flat finish with no lacquer top coat. The underside is plain which allows the owner to add stickers and graphics if they want but they look great just the way they are.
Bought as a Christmas gift for our nephew. He's not an expert or anything so I was looking for something that would work while he gets used to riding one. When I received it I pulled it out of the package to check it out and the construction was good. The wheels spun smoothly and the grip tape was nicely put on. I don't know how it would resist to some board slides but for a 15 year old just starting out its a good board.
GREAT board. Great design graphics. The boards deck has a real POP to it that makes it GREAT for tricks and a AWESOME beginner board. Only problem is It's super slow and requires a lot of work to maintain speed or to pick up speed period. A simple $20 wheel barring upgrade will fix that and BOOM PERFECT board, PERFECT caved in deck. Only 4 stars because of the lack of speed. I prefer my boards ready out of the box already pre-upgraded, but for the price, no point in complaining. Like almost all new boards, u have to ajust the wheels and the flex of the board to customize it to your liking. You won't regret it. But order it with some "Lucky" or "Red bearings" and your set.
The skater can gain greater clearance from the ground by jumping higher, popping faster, sliding the front foot farther forwards (starting the jump with the front foot farther back), and pulling the legs higher into the chest to raise the feet higher. Skaters attempting record-setting ollies even contort the legs so that board and feet are not directly below them, allowing the board to rise at or just below the level of the pelvis.
The type of skating the rider wants to do will inform the board choice, which sometimes involves skating a non-popsicle shaped board. But if you are just starting out, you can simply start with the traditional popsicle shaped deck that you probably recognize. As you skate more and get to know what shapes you like or what kind of skateboarding you enjoy best, your decisions will take into account for company, shape, width, and style of riding. Until then, choosing a board by its graphic is totally acceptable. For an overview on types of skateboard decks and riding styles, check out our Skateboard Decks Section in our Buyer’s Guide. Once you find a deck you like, you can simply select the default wheels, trucks, bearings and grip tape or you have the option to make it a complete.
The wheels of a skateboard are usually made of polyurethane, and come in many different sizes and shapes to suit different types of skating. Larger diameters (55–85 mm) roll faster, and move more easily over cracks in pavement and are better for transition skateboarding. Smaller diameters (48–54 mm) keep the board closer to the ground, require less force to accelerate and produce a lower center of gravity which allows for a better response time, but also make for a slower top speed and are better for street skateboarding. Wheels also are available in a variety of hardnesses usually measured on the Shore durometer "A" scale. Again like car tires, wheels range from the very soft (about Shore A 75) to the very hard (about Shore A 101). As the A scale stops at 100, any wheels labeled 101A or higher are harder, but do not use the appropriate durometer scale. Some wheel manufacturers now use the "B" or "D" scales, which have a larger and more accurate range of hardness. Modern street skaters prefer medium-sized wheels (usually 51–54 mm), as small wheels with lighter trucks can make tricks like kickflips and other flip tricks easier by keeping the center of gravity of the skateboard closer to the deck, thus making the deck easier to spin. Street wheels are harder (A 100/A 101). Vertical ramp or "vert" skating requires larger wheels (usually 55–65 mm), as it involves higher speeds. Vert wheels are also usually slightly softer (A 98/ A 99), allowing them to maintain high speed on ramps without sliding. Slalom skating requires even larger wheels (60–75 mm) to sustain the highest speeds possible. They also need to be soft and have better grip to make the tight and frequent turns in slalom racing. Even larger wheels are used in longboarding and downhill skateboarding. Sizes range from 65 mm to 100 mm. These extreme sizes of wheels almost always have cores of hard plastic that can be made thinner and lighter than a solid polyurethane wheel. They are often used by skateboard videographers as well, as the large soft wheels allow for smooth and easy movement over any terrain.
Grip tape is a sheet of paper or fabric with adhesive on one side and a surface similar to fine sandpaper on the other. Grip tape is applied to the top surface of a board to allow the rider's feet to grip the surface and help the skater stay on the board while doing tricks. Grip tape is usually black, but is also available in many different colors such as pink, red, yellow, checkered, camo, and even clear. Often, they have designs die-cut to show the color of the board, or to display the board's company logo. Grip tape accumulates dirt and other substances that will inhibit grip, so use of a grip eraser or rubber eraser is necessary after riding through mud or with dirty shoes.
In 1977, skate parks began cropping up all over the place, including Skateboard USA, where Gelfand began to spend most of his time. His buddy, Scott Goodman, is the one who gave Gelfand the nickname of “Ollie” and dubbed his aerial lipside the “ollie-pop.” Pictures of Gelfand during this time period clearly show him getting airborne and performing the trick associated with his name today.
This board is an excellent option for beginners because of its simplicity and durability. The lightly concave design allows for simple turns but doesn’t require the rider to be an excellent navigator. You can start off riding this deck down the street and use it as you learn ollies, kickflips and how to drop in to a half pipe. It will withstand it all and look good doing it.
