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.
Hey guys. I’m a girl and I am having some trouble with my ollie. I know the steps in order to do an ollie, but I can’t seem to do all of them. I can do a perfect pop on the back foot, but my problem lies in my front foot. (I am regular footed but idk if that matters) I know I just need to get my back wheels off the ground, but when I try to slide it, my foot just stays frozen. I try really hard to make it move, and when it does it just goes straight across, skimming the bottom of my shoes. Even then I can only move it half an inch. I have pretty mild griptape, that might change something? Idk.
Before we show you how to ollie, let’s get familiar with the legends that brought this skateboard trick to the masses. If it were a person, the history of ollie would start way back in 1974, when Alan Gelfand got his first skateboard from his father after his family moved to Hollywood, Florida from New York state. It didn’t take him too long to get the hang of it; he won the South Florida Skateboard championships two years later.
Shock pads are made of polyurethane and rubber. They are very similar to risers but vary in the fact that their sole purpose is to cushion the board from the trucks. Since the trucks are metal and the board wood, whenever the board hits the ground after doing a trick, the energy goes through the truck to the board ─ this has caused boards to crack, split, or even break in half, and shock pads were created to prevent this.
