Matt Liebsch Stone Grinding Skis

Stone grinding can restore a ski base surface when damaged from normal use, scratches, and over heating from an iron. Stone grinding will make your skis faster! Many skiers grind their skis once every few seasons but many racers grind each season to have the best performance and some serious racers will stone grind shortly before their “A” race to maximize ski performance. Skis can generally be ground multiple times. On the low end (heavy damage to the base hence much base removal) skis can only be ground 4-6 times but there are cases of skis being able to take up to 40 stone grinds over the life of a ski.

Pioneer Midwest uses a Wintersteiger Race Series machine that uses digital programming. This means we can recreate the same structure easily. Our machine is used only for Nordic skis and uses a Nordic specific stone and diamond for structuring the skis.

Our grind menu is simple to reflect how things are often done on the World Cup. KISS applies (keep it simple …) There is no sense in having complex structures on your skis that only work in niche conditions. In very general terms… cold snow, cold structure; warm snow, warm structure. As seen below, snow crystals can vary depending on both temperature and humidity Classic structures are generally linear in nature and skate grinds tend to be crossing. The reason is classic skis are always in motion when they interact with snow whereas skate skis are battling static release so the structure needs to be shallower and crossing to help the skis feel “free” Our structures are clean, efficient and take hand structure very well.

Your skis are constantly interacting with the snow underneath your foot. Snow conditions and consistency are constantly changing even over the course of the race or workout, so you want a grind that will not become a liability when they do. The snow crystals themselves are only half the battle, moisture content can play an even bigger role into how your skis feel. Without a recent stone grind, your skis ability to wick moisture is drastically minimized. On those warm days, a ski without structure can feel like attempting to drag a suction cup down the trail.

Our stonegrinds have been race proven at the highest levels of competition. From NCAA nationals to SuperTours, and Junior Nationals to Midwest marathons our grinds have been on the podium and propelled athletes to career best performances.

*Off-Season turn-around time varies*


Skating Structures:

  • SC0 ~ 10F< Cold squeaky snow. Green waxes only.
  • SC1 ~ 5-32F Universal grind can be skied warmer with hand structure. Cold snow up to 32F. We love this grind. (Previously HSC1)
  • SC2 ~ 20F-40F Wide range for blue to warmer violets and into reds with hand structure.
  • SC3 ~ 28F> All about wicking moisture. Wet old snow 28F+ and natural snow 35F+

Classic Structures:

  • CL1 ~ 15F< All snow types
  • CL2  ~ 10-40F Universal classic structure
  • CL3 ~ 28F> Wet snow, klister grind

 Ski Grinding Schedule:

Generally we have a 4 day turn around on ski grinding in-season. Below is a tentative grinding schedule to help you plan out when you need to drop your skis off if you want to have them ready by a certain date. We can take skis in on any date.
