A skateboard consists of a deck, trucks, wheels, bearings, hardware, and griptape. All parts come in a variety of sizes, graphics, colors, and signature pro series. The deck is the essential part of any skateboard. The deck ranges generally from 7.5" to 8.5". Skaters choose their board size for many reasons, but the basic deciding factor comes down to style of skating and foot size. Transition skaters usually ride a wider deck, while street skaters tend to go with a smaller deck. Skate brands such as Girl, enjoi, and Welcome offer a wide range of boards in regards to sizes and graphics. Skateboard trucks come in either a high or low setting, and also in a range of widths. The main factors in a truck, are how well they turn, and how well they grind. Independent, Venture, and Thunder, are truck brands that are well known for their turning and grinding capabilities. The skate hardware is generally either Phillips head or Allen key bolts. The skateboard wheels range from 50mm to 60mm. Some brands offer smaller and larger sizes, but 50-60mm is the general range. Like the deck sizes, wheel sizes depend on the skater's choice of terrain: Transition skaters tend to ride bigger wheels, while street skaters usually go with smaller wheels. Bones, Spitfire, Ricta, and Wayward wheel companies all make wheels for any terrain, whether you're a street shredder or a park burner. Skate bearings follow the ABEC rating system, which includes grades 1, 3, 5, 7, and 9. Bones, Bronson, and Andale are some of the top bearing brands in the skate market. CCS proudly carries all these brands, and many more.
In general an axle width should be chosen that is close to the width of the deck it will be used with. For example, a 7.75" wide deck will usually be fitted with trucks that have axles between 7.5" wide and 8.0" wide. (Standard truck axle nut size is 5/16"-24tpi UNF, and the thinner "jam" style with an optional nylon lock.) Trucks that are too wide can make doing tricks difficult and can cause the wheels to get in the way when the skateboard is being ridden. Trucks that are too small can be hard to maintain stability and can cause wheel bite to occur when turning.
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.
