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.
My fiancee purchased this via my account and he says that it has good concave shape and pop.Assembling was fairly simple, easier if you have a box cutter on hand to help with laying the grip tape. The deck was the best part but the bearings were good too. He thought the bushings were the worst, after about two hours of skating, both bushings were crushed and stuck in one direction. He's been skating for almost 13 years. Hope this helps!
If you are new to skateboarding and are looking to build a custom skateboard complete, the best place to start is with the deck. While not all boards are created equal, groms will do well on just about any brand skateboard offered at CCS as durability really won’t come into play until riders start to skate bigger gaps and transition. So your focus should primarily be on finding the right deck width, board graphic, and brand that resonates with you or the rider.
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 ollie is a fundamental trick in street skateboarding, and is used to leap onto, over, or off obstacles, or over gaps of unfriendly terrain such as grass or stairs. As so many other tricks depend on it - for example the kickflip and heelflip - the ollie is often the first trick to be learned by a new skateboarder. The ollie typically takes considerable practice to learn.
