Great News! Cold weather is moving in just in time for the Lutsen race weekend... High's in the low twenties and sub-zero lows require that sidewall & 2nd edge be cut back enabling you to achieve sharp edges. Hard waxes are the call for superior glide & durability. Low humidty = CH waxes with some cold powder along the edges to enhance durability and reduce base-burn. Make sure that when you are done racing to clean your skis with Swix Glide Wax Cleaner and re-apply Swix BP-88 or Raceservice SBC-1.
Good Luck!
