The N-Line is Rex`s new race line of fluor-free grip wax to replace the fluoro Pro-line waxes. These waxes are designed with Dual Compound technology, perfect ratios of pressure-sensitive and temperature-sensitive materials, and N-Kinetic technology, for glide and dirt repellence. The N-Line waxes are great on their own or as mixers and covers. N21G is a mild to cold condition grip wax specific to new snow. Added graphite helps reduce static and snowballing. It is best used in -1°C to -12°C on cold, dry, crystallized new snow. When the new snow has moisture, use the fluoro-free 30GB Racing Service Line Wax instead.
