SPEEDMAX 80 SKATE COLD 610 STIFF IFP"The new Speedmax 80 Skate Plus 610 is a lightweight race ski with an Air Core Carbon core for ambitious amateur racers. It provides more speed thanks to innovative Cold Base Bonding technology for optimal wax absorption and grindability. To protect the base, a thin layer of wax is applied to the skis which must be removed and brushed off before the first use. The Cold version is optimized for use at 28F ( 2C) and colder."
