BNS Grind System
The BNS grind naming system simplifies grind selection. The system is easy: Each name starts with “S” or “C” to designate skate/classic. Two numbers follow, separated by a decimal point. The first digit corresponds to moisture and temperature range on a scale of 0 (cold/dry) to 5 (warm/wet). The second digit corresponds to snow type ranging from 0 (new/sharp) to 5 (transformed/rounded). These names bring clarity to each grind’s characteristics and also allow you to easily compare grinds relative to each other just by looking at their names.
Grinding Menus
We recommend our core grinds on the simple menu as the starting point for everyone. These broad-range structures provide a solid foundation to handle every condition, whether you have one pair of skis or 20. Our simple grind menu is based on how many pairs of skis you have in your fleet. Ninety-five percent of skiers have one, two, or three pairs of skis, and we recommend different mixes of our core grinds based on how many skis you have to work with. To find the right mix of grinds for your fleet, choose skate/classic, and then pick the highlighted grinds for the number of pairs of skis you have. Every region has unique snow conditions. Skiers in the dry Mountain West will want to adjust toward the colder end of the menu, while skiers in the Northwest and California should consider moving to the warmer end of the spectrum. We are always happy to consult with individuals and teams to make recommendations that keep your life simple but ensure you get the best we have to offer.

Simple Grind Menu
Every region has unique snow conditions. Skiers in the dry Mountain West will want to adjust toward the colder end of the menu, while skiers in the Northwest and California should consider moving to the warmer end of the spectrum. For a skier in the Rockies, S0.3, S1.3, and S3.3 would be a great setup for three pairs of skis, while east- and west-coast skiers might go warmer with S1.3, S2.2 and S3.3 or S4.2.We are always happy to consult with individuals and teams to make recommendations that keep your life simple but ensure you get the best we have to offer.
2024-2025 Grind Menu Updates
-
The former S4.3 grind, ideal for warmer conditions, is now renamed S5.3.
-
S3.2 is now called S4.2, performing well in a range of conditions, especially in wet snow and new, warm snow that has fallen in the last two days. Temp Range roughly -3°C to +5°C (27°F-41°F)
-
The new S3.3 grind is an excellent universal plus choice, designed to handle various snow types across a broad temperature range around freezing, ideally +/-4°C, 25-39°F.
