| Why Stonegrind? For any or all of the reasons: to flatten a ski base, to open up (remove) fine layer(s) of P-tex that have become sealed from iron overheating; to create a particular base structure so the skis can be fast in given snow and humidity conditions. Most common reason your skis should be stoneground? Sealed ski bases due to overheating. Race ski bases need to be rejuvenated yearly. |
