Buying Skis
With hire fees increasing even though the equipment is often
still poor, and the problems of adjusting to new unfamiliar set-ups, it
is time to take advantage of the amazing value for money now available
through all levels of modern skis. It’s the best way to make sure
you have the right tool for the skiing you want to do, and you’ll
maximise your performance as you use a ski tuned to your ability and style.
The following is designed to help you choose your perfect set of skis
– often a daunting task but don’t worry, we have deliberately
de-mystified all the jargon and made simple all the facts (and you can
ski them on snow before you part with the cash: see our Try-Before-You-Buy
page). This is your guide to explaining the icons, graphics and technical
information you will find used throughout our ski section..
Skier Ability
So often in life to get the best you have to pay the most but this really
isn’t the case with skis. Expert level skis are expensive but are
actually only suitable for experts – unless you are on top of your
game 100% of the time and want a demanding highly tuned performer, don’t
go near these babies. If you are an intermediate, buy an intermediate
ski, they are not low tech punter skis but use many of the high-end expert
components tuned specifically to delight the intermediate skier. You will
ski better on it, enjoy yourself more and also save a bundle of money
you can put towards an extra weekend on snow. Be honest with yourself
and with our ski technicians, this way you can be sure to get the right
equipment. Think about your current ability and your aspirations, and
also where you are going to use the ski.
Jargon Buster
Radius
The phrase “radius” used in this catalogue/website refers
to a ski’s sidecut radius and can be thought of as the ‘natural’
turn size of that ski. Assuming that due to its curve, the edge of a ski
could be one part of a circle, then the sidecut radius would be the radius
of that circle. These figures are given in metres. Factors that will affect
the sidecut radius are the ski’s length and sidecut depth. The phrase
turn radius is slightly different as turn radius is variable and depends
on the person using the ski - applying more reverse camber or bend will
create a smaller turn radius.
Typically, skis designed for on-piste skiing will have a short radius
of 10 to 18m so they will initiate a turn and carve easily, whilst skis
designed for maximum off-piste use will have a 25m+ radius. Freeride skis
are somewhere in between as they need to function both on and off piste.
New for this season are the all terrain hybrid skis such as the Atomic
Metrons and Salomon Scramblers that have a small radius but can still
be used off piste due to their wide waist.
Sidecut/Shape
The phrase “sidecut” used in the catalogue/website refers
to the ski’s dimensions at the widest points of the tip and tail
and at the waist, or middle of the ski. Measured in mm, sidecut is shown
in the order: tip/waist/tail. The term sidecut can also refer to the distance
in mm’s equivalent to half the gap at the waist if a pair of skis
was put side by side, edge to edge, with both tips and tails touching.
A deep sidecut will create a ski with a small radius, so generally this
will suit a piste-orientated ski as it will carve turns easily. Skis with
shallow sidecuts will have a much larger radius suiting deeper snow as
turns are less likely to be carved and to have more shape would potentially
be trickier in cut up conditions.
As well as the actual depth of sidecut, or ‘amount of shape’,
the combination of the tip, tail and waist widths will also affect how
the ski reacts.
Waist: A wide waist found on Freeride and Backcountry
skis will offer lots of floatation and stability so you can cruise through
deep snow, but on groomed snow they will feel slightly sluggish as they
are slow to change edges. Narrow waists feel very quick from edge to edge
when on-piste but will not float so well off it. Typical sizes at the
waist are 62-68mm for piste skis, 69-75mm for all terrain, 75-85mm for
freeride and anything bigger than that is for the deep stuff baby.
Tail: Tail widths affect the feeling of carving at the
end of a turn, skis with wide tails like the Salomon Streetracers will
‘hold’ at the end of a turn locking you into the carve with
less loss of momentum, whilst skis such as the Atomic B:9 have a narrower
tail making them easier to skid but are more controllable.
Tip: Tip width is also important, for example a wide
tip and narrow waist give excellent turn initiation as the ski will roll
smoothly into a carve, this is especially noticeable on the Head i.C 160
and the other Head Cybers.
There are many differences in the sidecuts and shapes that will create
certain types of skis and it is worth noting the dimensions as you compare
models.
Selecting the correct size of ski
The size of the ski you need is dependent on a combination of factors.
Weight: Your weight is more important than your height
as it is this that makes the ski flex or ‘bend’. Heavier skiers
need bigger (or stiffer) skis so that there is more stability and surface
area, lighter skiers should think about smaller sizes as they may have
less power to flex the ski.
Ability/Aggressiveness: The longer the ski the more
edge there is for extra grip, and the more base for stability. Cautious
skiers should think about down sizing as they do not need the stability
at speed but would benefit from extra manoeuvrability of a smaller ski.
Intended Use: The end use has an important influence
on the size. The following recommendations are assuming height and weight
are roughly in proportion (again be honest!).
Piste Use - chin height to eye level, for easy
carving and responsiveness.
All Mountain - nose level to forehead, though
the Metrons, and to some extent the Scramblers, can be skied shorter than
this.
Freeride - eye height to top of head height
is a good size for extra floatation where you’ll need a few more
cm’s.
Freestyle - ski it nose level for the maximum
ease of spinning and rail tricks but go bigger for all mountain versatility.
Backcountry - go as big as you can handle for
maximum floatation (and lift queue kudos).
The size of your previous skis may also be a factor that should be considered.
For further help on sizing speak to our staff who can give you detailed
advice.
Whilst not listed in our ski tech info sections, another factor that
is also important is ski stiffness, both tip to tail and torsionally.
A stiff ski in length is harder to bend making it harder to carve but
is more stable at speed. Softer flexing skis will nurture confidence and
earlier improvements in technique because they require less energy and/or
skill. A torsionally stiff ski is more resistant to twisting forces when
on its edge and will therefore offer greater edge grip, whilst a torsionally
softer ski will not have the same grip but it will be easier to control
at slower speeds for cautious skiers. Again for further help on ski stiffness
speak to our staff who can give you detailed advice.
