This can be tricky to figure out, so just take your time and relax. The first few times you try and ollie, it helps to not worry about this part. You will end up doing a sort of half-ollie, popping just a little in the air. Or, you might fall! But, don't worry, this is all part of learning. If you want though, you can certainly start with rolling your ankle when you try and ollie - whatever works for you! Eventually, you will need to roll and drag, and you'll figure it out. Just take your time!
Skateboarding is all about creativity and finding new challenges. A great way to explore skateboarding is to ride different shaped boards, wider trucks, and different size wheels. As you progress and start to ride new terrain and skate different kinds of spots, you may find one wheel size or board shape works better for you than another. There’s no wrong or right anything. There are no rules. Except for maybe one, and that is to keep skating. Skate as often as you can. Never is this more true than in the beginning while you’re developing your style and fundamentals.
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.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
