Dominator Racezoom Old Snow 100g

To be used effectively, all conventional temperature specific waxes require fairly accurate
information about the snow conditions. But one rarely has this luxury. Most of us wax Friday
night and hit the snow Saturday morning, or the weather changes during a race, or snow
temperatures vary a lot in the sunny and shady areas of the racecourse. To adapt to this reality,
we developed the Zoom thermoactive waxes. These products change their properties rapidly
as a function of snow temperature and adapt to changes in snow conditions. Because of this
ability, they work very well over a broad range of snow temperatures (0°C to -10°C/ 32°F to
14°F), from wet to fairly cold snow. They can feel a little slower on extremely cold snow so we
augment them with the Bullet or Psycho extreme cold waxes when it gets that cold. This system
provides race proven results yet requires the kind of minimal information you can get with a
quick phone call to the ski patrol. You need to know only two things: The age of the snow (new
or old), and the snow temperature category (normal, cold, or extreme cold).

The Zoom system explained
Let’s first get a better understanding of the reasons why different waxes are needed. The
figure below shows the hardness of ice and three temperature-specific waxes (yellow, pink, and
turquoise) as a function of temperature. We use ice as a model but similar trends are observed
with the other forms of snow crystals. We see that although the hardness of the three waxes
changes little with temperature, ice hardens rapidly as it gets colder. Since the correct wax is
the one that is slightly harder than the snow, pink is best at –4°C and turquoise is best at –9°C.
It is also possible to use mixtures of waxes to achieve intermediate hardness values so a mix of
pink and turquoise is best for –7°C and a mix of yellow and pink at –2°C.
