Swix Cera NovaX High-Performance Glide Wax
Cera (Italian for Wax) and Nova (Bright Star)
Cera Nova was our dominant wax system for many years. Cera Nova was followed up with our new Cera NovaX:
- The new system allowed for 32 new products that gave us 152 recipes or different ways to use wax combinations/layers.
- Cera NovaX took 12 years to create using 740 test occasions with 3700 unique tests
- Testing was done on every skiable continent, at every skiable elevation, every type of air temperatures and snow conditions.
- In average Swix performed 24 hours of testing per formula (see chart below).
- This is equivalent to skiing 7400kmk or ¼ lap around the world or skiing from Lillehammer to Vancouver.
Which Race Wax to Choose
With so many waxes to choose from and so many different ways to apply I find it’s better to keep things simple!
Key factors for waxing:
- Proper wax selection will increase gliding by decreasing friction between the base and snow surface.
- Swix waxes are temperature sensitive. Each formula comes with a distinct icon, which tells you the iron temperature setting.
- Swix wax formulas are based on air temperature.
- Humidity factors will also factor in wax selection but use this more as a regional trend. There is no need to measure every single percentage. We live in a very dry climate but it’s easy to turn on the “Weather Channel’ to see what the actual humidity is.
- The snow crystal is my biggest concern since most races are held on man-made snow the snow crystal is extremely abrasive. With this key factor in mind, I recommend the use of harder/colder wax selection. It’s almost always better to wax a little colder than the actual predicted temperature.
- Lastly, there is “new snow”, “old snow” and “dirty snow” which require some thought. I will break this down in detail for each wax component.
Very basic wax chart! Still made in Oslo, Norway!
CHX – Swix Hydrocarbon Wax
Using the chart on the opposite page you can see that there are 6 temperature ranges on for CHX Wax. We recommend the use of this wax for training and freeskiing. These waxes are economical and for the most part, can cover a U10 for almost all conditions. Hydrocarbon waxes are fluoro free and are biodegradable.
LFX – Low Fluorocarbon Wax
Low fluoro waxes are a mix of hydrocarbon wax and the fluorocarbon additive. This fluorocarbon additive has been used for decades to enhance the glide factor. Low Fluorocarbon waxes are great for everyday training and racing. If the humidity is up slightly then LFX is a better option to the CHX.
HFX – High Fluorocarbon Wax
HF stands for High Fluorocarbon. There are 6 main waxes in this category, which are fluorinated hydrocarbon blends having a high percentage of a low melt point fluorocarbon additive -a result of CeraF technology. The waxes are unique because they provide fast acceleration, have proved effective in a wide range of temperatures, are durable and dirt resistant. HFX waxes are excellent when used alone, but ideal when used in combination with CHX or LFX as an overlayer. Conditions of high humidity are optimal for HFX waxes.
HFBW – High Fluorocarbon “Black Wolf”
Swix BW (Black Wolf) Waxes contain solid lubricants as additives, which gives advantages for coarse-grained snow, dirty snow, man-made snow and dry friction (very cold temps). The BW additive has considerable lower coefficient of friction compared with previous additives. Has been tested on World Cup alpine and XC with excellent results. Ok, so pretty much ideal race wax for Alberta/East Kootenays!
