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 1978, Alan Gelfand, who was given his nickname "Ollie" by Scott Goodman, learned to perform no-handed aerials in bowls and pools using a gentle raising of the nose and scooping motion to keep the board with the feet. There are numerous references to Alan Gelfand's Ollie with most notably pictures in the 1970s skateboarding magazine "Skateboarder".
The ollie is a skateboarding trick where the rider and board leap into the air without the use of the rider's hands. It is basically the combination of popping, sliding, and jumping on the skateboard all at the same time. Originated in vertical skateboarding, and later on flat ground, it is not intuitively obvious how the liftoff is achieved, making the movement visually striking.
The Krown Rookie Skateboard Complete 7.5 comes with thick, sturdy 7-ply maple wood deck. It gives you more control and permits you to perform various tricks. It features carbon steel ABEC-3 bearings, aluminum trucks, bushings and 54mm x 34mm wheels. This board is perfect for kids who are 8 years and older. It has a maximum weight capacity of up to 220 lbs.
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.
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.
