In skateboarding, grinds are tricks that involve the skateboarder sliding along a surface, making contact with the trucks of the skateboard. Grinds can be performed on any object narrow enough to fit between wheels and are performed on curbs, rails, the coping of a skate ramp, funboxes, ledges, and a variety of other surfaces. [1]
The move likely originated in backyard pools in the mid 1970s, as the early skaters gained in skill and confidence with their high speed carves around the top of the pool walls and one day unintentionally skated up to the edge of the pool, causing the trucks or board of the skateboard to slide (or grind) along the surface . The trucks of the time, often being merely 'borrowed' trucks from roller skates, didn't allow much contact due to their narrowness, but as skateboarding gained its own truck manufacturers who widened the hanger design, the possibilities for exploration became apparent, and all sorts of moves started popping up . There was a big leap in street skating starting in the 1990s [ quantify ]. It has evolved ever since. Today, grinds are commonly performed on handrails, lips of benches, tables, hubbas (ledge on a slope), on a hard normal ledge, a flatbar, or just simply anything that is possible enough to grind on it.
Grinding is damaging to materials which are not hardened for the specific purpose of the sport, as may be found in a skate park. The trucks are composed of a hard metal without lubricant or bearings on the grinding surface, so they literally do grind on the objects they slide across. Grinding can strip paint off of steel and wear down the edges of concrete, stone, aluminum, and wood building materials. Affected business owners and government buildings have put up anti-skate devices as a deterrent to grinding. [2] Grinding in public places may be seen as a form of vandalism and may cause skateboarding to be banned by business owners and city ordinances. [3]
Whether a grind is back-side (BS) or front-side (FS) depends on how rider approaches the rail or edge. If the skater approaches the rail with his back to it, the grind is a back-side grind. If the skater approaches the rail with the front of his body to the rail, the grind is a front-side grind.
Skateboarding is an action sport that involves riding and performing tricks using a skateboard, as well as a recreational activity, an art form, an entertainment industry job, and a method of transportation. Originating in the United States, skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue, with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding would be represented at the 2020 Summer Olympics in Tokyo, for both male and female teams. Skateboarding made its Olympic debut in 2020 and was included in the 2024 games.
A skateboarding trick, or simply a trick, is a maneuver performed by manipulating a skateboard, usually with one's feet, in a specific way to achieve the desired outcome – the trick.
Boardsports are active outdoor sports that are played with any sort of board as the primary equipment. These sports take place on a variety of terrains, from paved flat-ground and snow-covered hills to water and air. Most boardsports are considered action sports or extreme sports, and thus often appeal to youth. Some board sports were marginalized in the past. However, many board sports are gaining mainstream recognition, and with this recognition, they have gotten wider broadcasting, sponsorship and inclusion in institutional sporting events, including the Olympic Games.
Inline skates are a type of roller skate used for inline skating. Unlike typical roller skates, which have two front and two rear wheels, inline skates typically have two to five wheels arranged in a single line. Some, especially those for recreation, have a rubber "stop" or "brake" block attached to the rear of one or occasionally both of the skates so that the skater can slow down or stop by leaning back on the foot with the brake skate.
A skatepark, or skate park, is a purpose-built recreational environment made for skateboarding, BMX, scootering, and aggressive inline skating. A skatepark may contain half-pipes, handrails, funboxes, vert ramps, stairsets, quarter pipes, ledges, spine transfers, pyramids, banked ramps, full pipes, pools, bowls, snake runs, and any number of other objects.
A half-pipe is a structure used in gravity extreme sports such as snowboarding, skateboarding, skiing, freestyle BMX, skating, and scooter riding.
Inline skating is a multi-disciplinary sport and can refer to a number of activities practiced using inline skates. Inline skates typically have two to five polyurethane wheels depending on the style of practice, arranged in a single line by a metal or plastic frame on the underside of a boot. The in-line design allows for greater speed and maneuverability than traditional roller skates. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines.
A terrain park or snow park is an outdoor recreation area containing terrain that allows skiers, snowboarders and snowbikers to perform tricks. Terrain parks have their roots in skateparks and many of the features are common to both.
A longboard is a type of skateboard typified by longer decks and wheelbases, larger-diameter and softer (lower-durometer) wheels, and often lower riding height compared to street skateboards, though there is wide variation in the geometry and construction of longboards. Among the earliest types of skateboards, longboards were inspired by surfing, with early longboards drawing from the design of surfboards, resembling and mimicking the motion of riding a surfboard, but adapted to riding on streets in a practice known as sidewalk surfing.
Longboarding is a variation of skateboarding typified by the use of longer boards ("decks") with longer wheelbases and softer wheels. While longboards vary widely in shape and size, compared to street skateboards longboards are designed to be more stable at speed and to have more traction due to larger wheel sizes and softer wheel durometers. While standard street skateboards may typically be between 28 and 34 inches long, longboards can range anywhere from 32 to 50 inches in length. Ride characteristics of longboards generally differ from that of street skateboards due to the use of specialized longboard trucks that have different properties than those typically used with skateboards; while street skateboards use "traditional kingpin" (TKP) trucks that are optimized for tight turning radii, ollie and flip tricks, slides, grinds, and transition skating, longboards are typically paired with "reverse kingpin" (RKP) trucks that are designed for increased stability at higher speeds, more "surfy" carving characteristics, and/or greater ride comfort for commuting over longer distances.
Natas Kaupas is an American former professional skateboarder. He grew up in South Santa Monica, California, in the area known as Dogtown, and is of Lithuanian descent. He is often referred to as one of the first true professional street skateboarders.
A snowskate is a snow sliding device which can be described as a hybrid of a snowboard, and a skateboard. Unlike a snowboard which uses bindings to secure the board to a riders feet, a snowskate is typically bindingless. The lack of bindings allows the rider to perform more skateboard-like flip tricks on the snow as apposed to what can be done on a traditional snowboard. Although the bindingless nature of the snowskate allows for the aforementioned skateboard-like tricks, snowskates can also be ridden in a style similar to traditional snowboarding, but with the added challenge and freedom of riding and carving bindingless. There are many types of snowskates depending on the brand and styling of riding, but the most common are single deck and bi-level snowskates.
In surfing, skateboarding, snowboarding and aggressive inline skating, frontside and backside are terms that are used to describe how a person approaches an obstacle or performs a certain trick. In aggressive inline skating, frontside and backside are types of grinds.
Freestyle BMX is bicycle motocross stunt riding on BMX bikes. It is an extreme sport descended from BMX racing that consists of five disciplines: street, park, vert, trails, and flatland. In June 2017, the International Olympic Committee announced that freestyle park was to be added as an Olympic event to the 2020 Summer Olympics.
A freestyle skateboarding trick is a trick performed with a skateboard while freestyle skateboarding. Some of these tricks are done in a stationary position, unlike many other skateboarding tricks. The keys to a good freestyle contest run are variety, difficulty, fluidity, and creativity. This is an incomplete list, which includes most notable tricks.
A slide is a skateboarding trick where the skateboarder slides sideways either on the deck or the trucks.
A skateboard style refers to the way a skateboarder can ride a skateboard. Styles of skateboarding have evolved and are influenced by a number of factors including sociocultural evolution, mass media, music, technology, and corporate influence.
Street skateboarding is a skateboarding discipline which focuses on flat-ground tricks, grinds, slides and aerials within urban environments, and public spaces. Street skateboarders meet, skate, and hang out in and around urban areas referred to as "spots," which are commonly streets, plazas or industrial areas. To add variety and complexity to street skateboarding, obstacles such as handrails, stairs, walls, flower beds, bins, park benches, picnic tables, and other street furniture may be traversed as single tricks or as part of a series of consecutive tricks called a "line."
Skatestoppers are skate-deterrent or anti-skate devices placed on urban terrain features, such as benches and handrails, to discourage skateboarders from grinding on the surfaces where they have been installed. They are a form of hostile architecture.
An example of an everyday technology that's used to forbid certain activities is "skateboard deterrents," that is, those little studs added to handrails and ledges. These devices, sometimes also called "skatestoppers" or "pig ears," prevent skateboarders from performing sliding—or "grinding"—tricks across horizontal edges. A small skateboard deterrence industry has developed, with vendors with names like "stopagrind.com" and "grindtoahault.com."
