Bearings are rated by the ABEC scale (1-9), which has nothing to do with skateboarding. Manufacturers know skaters believe higher ABEC ratings mean faster bearings. They do not, and you won’t find high-quality bearings on off-the-shelf skateboards. Most of these completes are slow. Make a bearing upgrade a top priority. Good bearings can make almost any skateboard fast. This article by longtime pro Anthony Pappalardo gives an insider’s perspective on bearings.
Progressive designs deliver a more dramatic upward curve and a wider base, providing increasingly secure footing and a locked-in feel. The W-concave shape is more narrow with an additional center curve, allowing for a greater shift in energy between the heel and toe. This design also boasts more responsive control and quick turning capabilities. Tub concave decks resemble the radial shape, however their rails extend at a sharp angle instead of a gradual curve. Asymmetrical decks feature rails that extend at different angles, affording more power to a rider's heels when making turns. Less commonly used are decks with convex and completely flat shapes. Convex boards offer an upwards-arching shape, which some downhill skateboarders prefer for a more natural feel, whereas flat designs increase available foot space and are more popular for experienced riders looking to perform fancy tricks.
If you are completely new to skateboarding, consider taking a minute to read through the Skateboard Decks Section in our Buyer’s Guide will be helpful, but a good rule of thumb is: the bigger your feet, the wider your board should be. If you wear a size 9 and up, you can’t go wrong with buying an 8” board. Narrow boards are easier to flip while wider boards are more stable, but there are no hard and fast rules to skateboarding. The only way to really find out what you like is by trying new shapes, sizes, and brands. Brands like Welcome, Baker, Chocolate, Deathwish, and Element all have a wide variety of sizes, shapes, and graphics.
