Something about snowboards

Freestyle board
This kind of snowboard is destined for these people who love halfpipe, snowparks, boxes and slope style. These are boards for people who prefer jumping anywhere and on anything rather than riding on traditionally prepared runs. But models of freestyle boards also do well on prepared runs.

Freeride board
Boards of this kind do well both on prepared snowgroomed runs and on the virgin area. In these two groups of snowboars we can specify also subgroups, and these are: FR/FS, FS/FR or universal boards with a majority of one parameter above the other.

Construction
Just like car producers, who use for this production their own unique technical solutions, also snowboard producers use forthis production their own technologies orthey use generally known and accepted solutions. The most popular are:

- Fullcap- outside layer of laminate on the whole lengh of the board closes a core and unites directly with a carve of the board. This construction is often used at snowboards for beginners and intermediates- thanks to giving very good board weight in relation to its endurance. Boards made in this technology are much harder than boards made in sidewwwalls technology
- Slant sidewall- wooden core is protected by “ABS”. It’s a construction very popular in freestyle boards. ABS increases board resistence for side damages, stratification or deformations. This solution has also an influence on much easier slide renovations and carves sharpening.
- Straight sidewall- construction used mainly at Alpine boards because of using hard wood, protecting the inner core and joining with thin ABS layer outside. It gives bigger pressure and active carve stiffening.

Core in snowboards
Very popular foam (in other words foamy poliurethan) is used for making snowboard core. Foam only is used in children’s snowboards and in snowboards from the “down shelf” for adults. I this second case core which is made of a foam doesn’t ensure proper endurance and springiness. These snowboards are decidedly lighter but I discourage buying them. Combination of foam and wood gives very good core properties- it is springy and resistant. The most popular material for core is a wood. There are a lot kinds of wood which are used for producing cores; among others there are finnish pine, poplar or balsa. The core isn’t an uniform piece of wood lied down ooon the whole lenght of the board, but these are very thin, sticked together layers, lied along or transversely. Using different kins of wood lied down on different levels of the core improves its characteristics at whole lenght and it enables getting adequate core properties on particular segments. Very often the core is much fatter under the bindings and thinner in the front, on the back and between bindings (it increases the control at turning). Very popular is adding to the wooden core some kevlar and carbon fibres what considerably increases the core endurance with simultaneous decrease of the board weight.

Kinds of slides
The most often used slides are made of P-Tex (polyethylene). This material has many variations depending on board category: e.g. P-tex 1000, P-tex 2000, Superglide. Slide in a very cheap boards doesn’t require too much care, but at the same time they are the slowest and the least resistant. It looks a little bit different in medium and high class boards where the slide has better riding and endurance parameters, but in return it demands very often waxing and conserwations. Boards equipped with Electra (graphite slide) or Indium slides demands the most care.
