Many TorbjornSport members participated in the recent US Masters Nationals in Marquette, Michigan. The conditions were with the exception of the first race, the 30/20 kilometer skate race cold and windblown. We had very good skis in all four races. Here is what we waxed with as well some details regarding application of cold waxes and some suggestions on when to choose synthetic waxes versus fluorinated or fluorocarbons in cold snow.
Wax combinations used at Masters Nationals
30 k freestyle -three inches of new snow, temperatures in the mid to high twenties. Medium/high humidity.
Wax: Base of SOLDA S-30 over F-15 Violet covered with HPO5 Fluorocarbon.
I would have changed to using F-31 Violet as base if I had more time (and energy) available that morning, but I was convinced that it would work well and it did — great skis.
Other possible good combinations: SOLDA Cold Fluor or mix of Cold Fluor and HPO5 over F-31 Violet.
Relay and Pursuit — a few inches of new snow, 3-4 Fahrenheit, medium humidity, windblown
Wax: SOLDA S-30 over S-20 — great skis
15 kilometer Classic — New cold windblown snow. Low of -6 F and high of 3 F
Wax: SOLDA F-15 Violet as base, HC28 (black hydro carbon) covered with S-30. Great skis for the conditions.
Fluorocarbons or Synthetic Cold waxes?
I suggest that you avoid fluorocarbons when the conditions are truly cold and the humidity low or medium and will remain that way during the race. Cold synthetic waxes like SOLDA S-20 S-30 will in these conditions be the fastest also in a long race.
This wax will work best in low to medium humidity conditions. S-20 is very adaptable to a wide range of temperatures and changing snow conditions — new snow, old snow, or shadowy sections interspersed with sunny areas on the course. Contains a small amount of graphite, giving it is antistatic properties. When the temperatures are between 4 and 14 F, S-20 may be applied over a layer of S-30 or F-15 Blue. When the temperature is 10 to 20 F, we will often use F-15 or F31 Violet as base layer.
I prefer S-30 (not S-20) until its 10F or warmer.
