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 [1]. 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.
Sublimation (phase transition) is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase. Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram. In this case, ink is transferred to a base layer, fibreglass for example, through heat and pressure, the result is a full color graphic that will not come off as easily as the more common heat transfers. This application is often found with bamboo boards and composite construction longboards where fibreglass can allow for various degrees of flex or stiffness depending on the ride you're looking for, cruising and carving versus slalom and downhill.
In this modern era, manufacturers are incorporating hi-tech processes and top-shelf materials into the construction of the skateboard. Companies such as Almost have several versions of hi-tech decks such as the Impact, Double Impact, and Uber Light Series. Element makes Highlight decks with inlayed fiberglass beams, and Foundation has its signature Fiberprime decks. Other manufactures such as Flip, Habitat, Plan B, Skate Mental, and Zero offer boards with high-end P2 Construction. Hi-tech decks differ from traditional 7-ply Maple in that they are inlayed with Carbon Fiber, Fiberglass, Poly Ply, or Kevlar to produce a stronger skateboard with more pop. For more options, head over to our stellar selection of Hi-Tech Decks! Although hi-tech decks have made a strong presence within the market, standard 7-ply Maple remain the gold standard. This is due to the solid feeling and pop afforded through layering 7 Maple wood veneers together. The large majority of skateboard decks offered are constructed of 7-ply Maple. Most board manufacturers offer both high-tech decks and standard 7-ply Maple. No matter what you desire, CCS offers a complete selection in multiple sizes, shapes, and construction types!

4 amazing skateboards in one nice lot. 1. 1990's Tony Hawk Conplete Skateboard, original falcon 3 design. With Rekon trucks and firelite classic wheels. 2. Sk8mafia Lucero deck. Signed by John Lucero. Brand new deck. 3. 1031 deck signed by entire team on a brand new creepy crawl deck. 4. Brand new super rare Big Mess deck with Blast design. This deck is extremely rare and is a must have for any collector. Both the signed decks are personalized to a guy named Jason that owned a skate shop here in Grant's Pass Or. Those guys were on his wall for a long time before he went out of business. If you have any questions or concerns please let me know. Thanks for looking. Steve
