Boards , Boots , Bindings

The various components of a snowboard are:
Core: The core is the interior construction of the snowboard. It is typically comprised of laminated fiberglass around wood. Beech and poplar are the most common woods, though other woods are used such as bamboo and birch. There have been continued experiments with aluminum, composite honeycomb, foam and resin to change, or substitute, the standard wood core. Desired properties of the core include dampening, rebound, strength, flex and reduced weight.
Base: The bottom of the board that is in contact with the snow surface. It is generally made of a porous, plastic (polyethylene) material, that is saturated with a wax to create a very quick and smooth, hydrophobic surface. P-Tex is a brand name that has become synonymous with base material. It is important that the base be "slippery", with respect to the snow surface and board interaction. Bases are made to have amorphous areas that are porous to wax. Wax is an important finishing product for all base materials. Not only does it allow the snowboard to have a smoother glide, but it also allows the rider to change the characteristics of the base and adjust the board to the snow conditions. Different base waxes are available for different temperatures. The base, when maintained, will have a designed base structure that not only channels snow, air and water, but leaves it open enough for wax to penetrate deep inside it. This pattern is created with a stonegrind machine at the factory or a local ski shop. If a base is left without wax for too long, it will begin to oxidize and no longer accept wax as generously as it once had. A stonegrind can remove layers of oxidation from the board and open up its amorphous areas too more readily accept wax. If the base is damaged, it is common to have it repaired in order to protect the core from exposure as well as reducing friction.
Extruded: The P-Tex is cut from a large sheet, or squeezed out of a machine much like "Play-Doh". A low maintenance base, it is the least expensive and easy to repair. Extruded bases are smoother and less porous than other bases. They do not saturate with wax well, and tend to slide slower than other bases. But left unwaxed they do not lose much overall performance. Extruded P-Tex is also cheaper than sintered P-Tex
Sintered: P-Tex base material is ground to powder then reformed with pressure and heat, and cut to shape. A sintered base is very porous and absorbs wax well. Sintered bases slide faster than extruded bases when waxed, but will be slower if unwaxed for a period. They are more expensive, and harder to repair.
Sintered Hybrid: Sintered bases may have graphite, gallium,indium or other materials added. These materials are used increase glide, strength, "wax hold" and other desired characteristics.
Edge: A strip of metal, tuned normally to just less than 90-degrees, that runs the length of either side of the board. This sharp edge is necessary to be able to produce enough friction to ride on ice, and the radius of the edge directly affects the radius of carving turns, and in turn the responsiveness of the board. Kinking, rusting, or general dulling of the edge will significantly hinder the ability for the edge to grip the snow, so it is important that this feature is maintained. However, many riders who spend a fair amount of their time grinding park rails, and especially handrails, will actually use a detuning stone or another method to intentionally dull their edges, either entirely or only in certain areas. This helps to avoid "catching" on any tiny burrs or other obstructions that may exist or be formed on rails, boxes, and other types of grind. Catching on a rail can, more than likely, result in a potentially serious crash, particularly should it occur on a handrail or more advanced rail set-up. In addition, it's relatively common for freestyle riders to "detune" the edges around the board's contact points. This practice can help to reduce the chances of the rider catching an edge in a choppy or rutted-out jump landing or similar situation. It is important to keep in mind that drastic edge detuning can be near-impossible to fully reverse and will significantly impede board control & the ability to hold an edge in harder-packed snow. One area where this can be quite detrimental is in a half-pipe, where well-sharpened edges are often crucially important for cutting through the hard, sometimes icy, walls.
Laminate: The snowboard's core is also sandwiched on the top and bottom by at least two layers of fiberglass. The fiberglass adds stiffness and torsional strength to the board. The fiberglass laminate may be either biaxial (fibers running the length of the board and more fibers 90 degrees perpendicular to it), triax (fibers running the length of the board with 45 degree fibers running across it), or quadax (a hybrid of the biax and triax). Some snowboards also add carbon and aramid (also known as Twaron or Kevlar) stringers for additional elasticity and strength.

Snowboard boots are mostly considered soft boots, though alpine snowboarding uses a harder boot similar to a ski boot. A boot's primary function is to transfer the rider's energy into the board, protect the rider with support, and keep the rider's feet warm. A snowboarder shopping for boots is usually looking for a good fit, flex, and looks. Boots can have different features such as lacing styles, heat molding liners, and gel padding that the snowboarder also might be looking for. There are snowboard boots that are made for most bindings and some that are made for "step in" style bindings. Although step in boots will need to be purchased in tandem with their corresponding bindings[3]. Snowboard boots differ from other types of boots in that they provide internal support to transfer the rider's movements to the board. Some boots that look like snowboard boots, but are not real snowboard boots, are unsuitable for snowboarding.

Bindings are separate components from the snowboard deck and are very important parts of the total snowboard interface. The bindings main function are to hold the riders boot in place tightly so the rider can transfer their energy to the board. Most bindings are attached to the board with four screws that are placed in the center of the binding. Although a rather new technology from Burton called Infinite channel system[4] uses two screws, both on the outsides of the binding.
There are several types of bindings. Strap-in, step-in, and hybrid bindings are used by most recreational riders and all freestyle riders.
Strap-in - These are the most popular yet technically deficient concept in snowboarding. Strap-in bindings were conceived before snowboard specific boots existed. With the lack of proper footwear, snowboarders used any means necessary to attach their feet to their snowboards and gain the leverage needed for turning. Typical boots used in these early days of snowboarding were "sorels" or "snowmobile" boots. These boots were not designed for snowboarding and did not provide the support desired for doing turns on the heel edge of a snowboard. As a result, early innovators such as Louis Fournier conceived the "high-back" binding design which was later commercialized and patented by Jeff Grell. The Highback binding is the technology produced by most binding equipment manufacturers in the snowboard industry. The leverage provided by Highbacks, greatly improved board control but produced large amounts of strain on the riders feet. Snowboarder's such as Craig Kelly adapted by using plastic "tongues" to protect their feet from strap-pressure. In response, companies such as Burton and Gnu began to offer "tongues" to relieve the pressure caused by strap-bindings on the top of the riders feet.
• As the snowboard market grew bigger companies began to produce boots specifically for snowboarding which helped to absorb the forces and pressure caused from Highback bindings with Straps. With modern strap-bindings, the rider wears a boot which has a thick but flexible sole, and padded uppers. The foot is held onto the board with two buckle straps - one strapped across the top of the toe area, and one across the ankle area. They can be tightly ratcheted closed for a tight fit and good rider control of the board. The downside for this is that the straps direct forces through isolated points on the top of the riders feet which can cause pain and permanent damage to the foots bone structure. Straps are typically padded to relieve the pain cause from these pressure points.
• The other downside is that strap-in bindings take longer to put on, usually requiring the rider to sit in the snow and bend over to adjust the straps. Also, because there are two points of pressure, the strap locations must be adjusted for each individual rider, making it more cumbersome for rental operations. Cap Strap bindings are a recent modification that provide a very tight fit to the toe cup which makes excellent edge control. The drawback to Cap Straps is that they compress the riders feet from toe-to-heel, requiring stiff-soled boots to keep the Cap Straps from mechanically "scrunching" the riders toes when cap straps are over-tightened Stiff soled boots can reduce the pain and resulting loss of performance caused by over-tightened cap straps . Such companies as Salomon, Rossignol, K2 Sports, Rome, Tech Nine, Ride, Flux, Burton, Union, Drake, and Forum have created different models of cap straps.
Step-in - In response to the lack of innovation in snowboard binding and boot technology, snowboarders began to experiment and develop step-in binding and boot technology. Independent innovators within the sport recognized the justifiable need for better snowboard boot and bindings to reduce damage and pain caused to snowboarders feet from Strap-in bindings.
Innovators of Step-In systems produced prototypes and designed proprietary Step-In boot and binding systems with the goal of improving the performance of snowboard boots and bindings.
• As a result, the mid-90's saw an explosion of Step-in binding and boot development. New companies, Switch and Device, were built on new Step-In binding technology. Existing companies Shimano, K2 and Emery were also quick to market with new step-in technology. Meanwhile early market leaders Burton and Sims where noticeably absent from the step-in market. Sims was the first established industry leader to market with a step-in binding. Sims licensed a step-in system called DNR which was produced by the established ski-binding company Marker. Marker never improved the product which was eventually discontinued. Sims never re-entered the Step-In market.
• The risk of commercial failure from a poorly performing Step-in binding presented serious risk to established market leaders. This was evidenced by Airwalk who enjoyed 30% market share in snowboard boot sales when they began development of their step-in binding system. The Airwalk step-in System experienced serious product failure at the first dealer demonstrations, seriously damaging the companies credibility and heralded a decline in the companies former position as the market leader in Snowboard boots. Established snowboarding brands seeking to gain market share while reducing risk, purchased proven Step-In innovators. For example snowboard boot company Vans purchased the Switch Step-In company, while Device Step-In company was purchased by Ride Snowboards.
• Other Strap-In binding and boot companies such as Tech-Nine, Northwave eschewed Step-In technology altogether, choosing instead to focus on improving Strap-In technology to the best of their ability. Rather than expose themselves to the risk and expense associated with bringing a superior Step-In system to market, established market leaders such as Burton also chose to focus primarily on improvements to existing Strap-In technology. However, Burton eventually released 2 models of Step-In systems, the SI and the PSI, Burton's SI system enjoyed moderate success, yet never matched the performance of the companies Strap-In products and was never improved upon. Burton never marketed any improvements to either of their Step-In binding systems and eventually discontinued the products.
• However, popular opinion, led largely by consumer advertising, focused simply on the inconvenience of strap-in bindings, suggesting that step-ins were created to make entry easier for beginners, allow for fast ski-lift to slope transition, and appeal to the rental market. Step-In systems still present an opportunity to improve the sport by allowing the riders feet to maintain structural integrity and offer increase performance along with improved comfort and convenience. Convenience is arguably the least important concern to most snowboarders although many of the aging snowboard population may find this trait appealing.
• Popular misconceptions persist that relative to strap-in bindings, step-in bindings use a stiffer shoe sole and boot to maintain responsiveness in compensation for the lack of over the foot restraining straps and (sometimes) lack of binding highback. However, modern snowboard boots feature stiff soles and rigid tongues to alleviate foot pain caused by over the foot restraining straps, whereas Step-In systems allow for softer flexing boots which allow the riders feet room to function properly.
• Most Popular (and incompatible) step-in systems used unique and proprietary mechanisms, such as the Step-Ins produced by Burton, Rossignol and Switch. Shimano and K2 used a technology similar to clipless bicycle pedals. Burton and K2 Clicker step-in binding systems are no longer in production as both companies have opted to focus on the strap-in binding system. Rossignol remains as the sole provider of Step-In binding systems and offers them primarily to the rental market as most consumers and retailers alike have been discouraged by the lack of adequate development and industry support for Step-In technology.
Rear Entry - There are also proprietary binding systems that seek to combine the convenience of step-in systems with the control levels attainable with strap-ins. An example is the Flow binding system which is similar to a strap-in binding, except that the foot enters the binding through the back (which then clips into place) rather than the top. The rider's boot is held down by an adjustable webbing that covers most of the foot. Newer Flow models have connected straps in place of the webbing found on older models; these straps are also micro adjustable. In 2004, K2 released the Cinch series, a similar rear entry binding; riders slip their foot in as they would a Flow binding, however rather than webbing, the foot is held down by straps.
Highback - A stiff moulded support behind the heel and up the calf area. The HyBak was originally designed by inventor Jeff Grell and built by Flite Snowboards. This allows the rider to apply pressure and effect a "heelside" turn.
Plate - Plate bindings are used with hardboots on Alpine or racing snowboards. Extreme carvers and some Boarder Cross racers also use plate bindings. The stiff bindings and boots give much more control over the board and allow the board to be carved much more easily than with softer bindings. Alpine snowboards tend to be longer and thinner with a much stiffer flex for greater edge hold and better carving performance.
Snowboard bindings, unlike ski bindings, do not automatically release upon impact or after falling over. With skis, this mechanism is designed to protect from injuries (particularly to the knee) caused by skis torn in different directions. Automatic release is not required in snowboarding, as the rider's legs are fixed in a static position and twisting of the knee joint cannot occur to the same extent. Furthermore it reduces the dangerous prospect of a board hurtling downhill riderless, and the rider slipping downhill on his back with no means to maintain grip on a steep slope. Nevertheless, some ski areas require the use of a "leash" that connects the snowboard to the rider's leg or boot, in case the snowboard manages to get away from its rider. This is most likely to happen when the rider removes the board at the top or the bottom of a run (or while on a chairlift, which could be dangerous

Regular vs Goofy

Goofy refers to having your right foot as your forward most foot. The term goofy is used for all sorts of board sports including: surfing, skateboarding, wake boarding and so on.
Riding goofy does not mean riding switch or fakie. Riding switch, or fakie, refers to riding opposite your regular way.
So if you are goofy, to be riding switch or fakie you would need to be riding so that your left foot was forward.
The hardest part for beginning snowboarders is to know if they ride regular or goofy. There are a couple little tests that can help figure this dilemma out. These tests are best done by someone else because the person getting tested will psych themselves out mentally when they are trying them.
Test 1: Just have person naturally step onto a skateboard. They will typically step onto the board in a way that feels most comfortable. Which ever foot is forward on the skateboard is typically the foot you put forward on a snowboard.
Test 2: Have the person step up a step. Typically the foot the person uses to put on that first step is the foot that should go forward on the snowboard.
Test 3: Gently push the person from behind. To catch their balance they will normally put one foot forward first. This is the foot that is then put in the front of the snowboard. Don’t knock them over, that is usually a good way to loose a friend, get your butt kicked or loose the sale if you are doing it at a shop.
Test 4: Ask the person. They are most times the exact opposite of what they say they are. This should be the final test if the first three didn’t work real well.

Snowboard vs Ski

Skiing and snowboarding are alike in that they are both downhill and are both the source of countless hours of fun and exhilaration Some of the differences, however, that you'll find between them include:
Snowboard riders constantly have to sit or exert energy to remain on edge while they are stationary. Unlike skiing, you will not have poles to help you remain upright and standing when you are not moving.
Snowboarding is a lot easier on the knees compared to skiing. Knee injuries are not as common in snowboarding as they are in skiing. Snowboarding can, however, be a lot more brutal on your wrists so make sure you wear some wrist guards.
You'll start to develop a deep hatred for flats when you're starting out with the snowboard. Again, you won't have your ski poles to bail you out.
You will, however, begin to fall in love with deeper and softer snow. Snowboards work nicely in powder and crud while skis are better in bumps and ice.
Getting up after a fall on a snowboard is a skill in itself but once mastered should prove to be easier and faster than having to put your stuff together again after falling on skis.

Snow board tricks

In the past posts of mine i told you about 2 different kind of riding style freeride and freestyle , freestyle people like to jump use the park do whatever do for play but freeriders choose a route and respect the mountain while they are riding in that road .
Here are some tricks in freestyle
Riding fakie refers to riding in a backward direction on your board i.e. with your rear foot leading. This will be one of the most fundamental skills in freestyle snowboarding which, apart from making you a more complete and versatile rider, will allow you to perform various spin moves in the air or on the snow.
To develop competence in riding fakie, practice key maneuvers such as traversing, stopping and turning but instead of leading with your front foot, lead with your rear foot instead. Persist with developing confidence and control and practice in various terrains, conditions and trails until you are comfortable with riding backward.
Tip Rolls
A tip roll involves flipping or rolling your board over 180 degrees to change from forward to fakie while the board's tip remains on the snow. To execute this maneuver, move your weight far forward and lift up your rear foot so that the tail of your board rises off the ground.
Start with a small lift first before gradually increasing the height. With the tip of your board still on the ground, practice swinging the tail until you can swing it all the way around to the other edge and ride fakie.
Once you are comfortable performing the tip roll from forward to fakie, practice swinging the board over with the same technique from fakie back to forward. As always, practice with both edges.
Catching Air
Now it's time to catch your first air. If you have access to a terrain park, look for structures designed for beginners. Otherwise, find an area with a few bumps or small berms to jump off from.
Move toward the jump at a low to moderate speed while looking ahead with your hands in front of you. At the top of the jump, remain balanced over your board and look straight ahead at all times while you are in flight. Do not look down! This has a tendency to badly affect your balance causing you to crash to the ground.
As you prepare to land, keep looking ahead and bend your legs to absorb the impact of your landing before riding out to search for your next jump.
You can also get some air on a flat ground by performing a maneuver called the ollie. Shift all of your weight toward the tail of the
board until the tip of your board begins to rise and allow your board to pop into the air.
As you gain in confidence when jumping, you can grab your board while in mid-air. Grabbing your board will provide extra stability in the air while also helping you to perform spins and inversions more effectively. Plus it just looks so cool!
Make sure you bend your legs to bring the board up to your hand rather than bending downward to grab your board which can put you off-balance. Experiment with grabbing various sections of your board with either hand whether it be the tip, tail, toe edge or heel edge of your board.
Being able to spin in the air will serve as the basis for which other more advanced freestyle tricks can be performed. Mastering the technique, however, will take plenty of practice and persistence.
Start by practicing 180 degree spins while on a gentle slope. While traversing on your toe edge, bend down low and wind your body up in a direction opposite to your intended direction of spinning.
Jump straight up and uncoil your body to begin your spin while using your arms to maintain balance. While spinning, look in direction you will be spinning and then in the direction you will land. Bend your knees and absorb the impact while landing on your heel edge and continue to ride fakie.
As always, practice on both edges and when you can jump and spin from forward to fakie, practice going from fakie to forward again. When you've mastered a 180 degree spin, practice doing a full 360 degree spin using the same principles except you'll be moving in the same direction on the same edge when you land

Freeride Vs Freestyle

There are 2 styles that you can choose while boarding and it depents on the mood of your nature .
The freeride style is the most common and easily accessible style of snowboarding. It involves riding down any terrain available. Freeriding may include aerial tricks and jib tricks borrowed from freestyle, or deep carve turns more common in alpine snowboarding, utilizing whatever natural terrain the rider may encounter.

In freestyle, the rider uses manmade terrain features such as rails, boxes, handrails, jumps, half pipes, quarter pipes and many other features. The intent of freestyle is to use these terrain features to perform a number of aerial or jib tricks.
