What’s the Wax? Birkie Tips

HAYWARD, Wis. — The American Birkebeiner expo was jumping with athletes on Friday afternoon, many of which buzzed around industry tables seeking advice from ski professionals.

What’s the wax?

With temperatures expected to be in the 20’s later Saturday morning, most everyone was recommending blue.


Here are a few tips from the service pros as seen on their websites or expo newsletters:

Boulder Nordic Sport:

  • Ski Selection: Early waves: med to stiff flex cold ski, Later Waves: Medium flex Cold Ski.
  • Stone Grinds: Skating S1.3 (CV0), S1.2 (S1-0x), S0.2 (0.55), S2.2 (S2-1x), Classic: C1.2 (XTi2), C2.2 (Li2), C0.2 (ZR1XL).
  • Base Layer: SkiGo LF Graphite
  • Race Paraffin: Holmenkol Matrix Blue or Ski*Go HF Blue
  • Fluoro Powder: Holmenkol Mid 08 or Solda HP05 or Ski*Go C105
  • Topcoat: Holmenkol Speedblock Cold
  • Structure: Holmenkol Structure Tool (one roller) or Finite L04/AF10
  • Kick: Clean the kick zone, rough up kick zone with sandpaper, iron in a binder layer of Toko Green hard wax/binder. We tested quite a lot of kick wax Friday at 10AM and found the following recommendations. Conditions on race morning are supposed to be colder, with more new snow possible, so this may need to be adjusted on race morning!
  • Guru Green for those who are skiing early and have solid technique.
  • Rode Super Extra for those in later waves or who need a little extra kick. It had great kick and was the fastest of everything we tried except Rode Super Extra has better kick and is still almost as fast as Guru Green. SkiGo HF Blue was also quite good, although with the new snow coming, SkiGo HF Violet might be a better choice.


Fast Wax:

  • Glide Wax: Apply 2 layers of HSF 20 Tan over 1 layer of HSLF-20 Blue. Top coat with Flite Cold, Iron in using the Fast Wax Base Saver
  • Grip Wax Options: (Make sure to rough up your wax pocket with 100 grit sand paper before waxing)
  • Iron in Rode Black Binder, cork in and let cool, then cover with several layers of Rode Multigrade Blue or Rode Multigrade Purple, –> Rode Violet Special
  • Iron in Rex Blue Power Grip or Grip Tape then add a layer of Rode Multigrade Blue or Rode Mutligrade Purple –> Rode Violet Special


Start Wax:

  • Glide: Start Blue for snow 10F-20F: It will be a high humidity day with plenty of moisture and dirt. The more Fluor skiers use, the faster the skis will be throughout the race. … The skiers in the back 1/3 will have air temps above this range but the snow will remain colder and with the extra dirt farther back, Blue is still ideal. Choose between SG6, FG16, LF07 or HF70 based on your budget and goals. Two layers of Blue with your highest Fluor on top. … For 100% Start Speed use SF10g or SFR 99 block or Nano N7 — 100% Finishing Fluors.
  • Kick: Start Blue. Iron in Base Wax on roughed up kick zone to keep your kick in your kick zone for 22 km or 54 km. Add 5-8 thin layers of RF Blue. RF Blue has the widest temp range 14-15F of all our blues and has a lot of Fluor for dirst and moisture. Terva Tar Blue (the poor man’s Fluor) would be another good option for those that have it but we would recommend the durable Synthetic Blue under it for durability.



  • Glidewax: All waves, both techniques: Apply LF Moly, scrape and brush, then apply HF Blue, scrape and brush. Finish by rotocorking JetStream Blue, brush with a dedicated nylon polishing brush and polish with a thermopad. “Quick ironing” the JetStream Blue and corking over it is also a great option. See for demonstration.
  • Gripwax: Rough kick zone with 150 grit sandpaper, apply Nordic Base Wax Green, iron in, cork smooth, let cool. Then apply one layer of Nordic GripWax Blue, cork smooth, and cover with Base Wax Green, cork smooth. Then Blue, Green, Blue, all full length of zone. Follow with Green, Blue, Green, Blue, in middle of kick zone. Later waves should carry GripWax Red and a cork.
  • Structure: A fine linear structure covered by one pass with the Blue Structurite tool (before JetStream application) will best suit these conditions.
