*Above you can see the difference between factory structure vs high-quality Nordic structure machines like our Tazzari. There is a big difference in grind/speed quality. We recommend grinding all new race skis and getting old skis ground at least once per year.
The machine that we use for stone grinding is a Tazzari RP23. This is a precision race-level machine that prepares cross-country skis consistently with top-quality grinds and structures. The same model machine is used by numerous national teams around the world and has prepared skis for countless World Cup and Olympic medals.
Our specific model is a brand new 2020 production with the latest software updates and technology. Attached to the machine is an oversized industrial chiller that keeps everything running at a specific operating temperature so that your skis are ground with the utmost precision every single time. Between every connection on the machine we have filters to keep old base material out of
"Vario Tech" is the ability of the Tazzari to change the drive speed of the feed wheel as well as the downward pressure on the ski throughout the camber. With this ability, structures can be adjusted “on the fly” and at certain parts of the ski to maximize the performance of what the ski is doing in that given spot. At Pioneer Midwest, we have the ability to see where and how pressure changes over the length of a ski with our flex tester and ski analysis. The combination of our ability to see how and where your ski reacts to weight, and the ability to change the structure at that point is unique to our shop. With this combination, we are able to tailor each ski grind to a given customer and structure for you that isn't available anywhere else.
We are able to cut any structure with different "Vario" settings to maximize your ski speed in every condition. Testing these Vario structures, we have seen skis that are drastically freer underfoot and have improved top-end speed over non-vario structures. Vario not only allows you to flush out moisture and humidity under your foot where it's most necessary, but it also allows you to break up snow crystals and create humidity where you need it to help that ski release and break away from the snow in the initial contact zones.
Overall, it allows you to run grinds that you know are consistent and universal in warm traditionally tricky conditions and still get excellent results. Our testing and contact with techs at the top level of competition have truly solidified our mindset behind keeping a grind menu simple and using structures that you KNOW always run well. We are able to make universal structures run warmer by changing the moisture buildup under the ski without affecting the width of the structure which determines whether a grind trends towards newer or older snow.
Our technicians have extensive training on the use of this Tazzari machine and have prepared thousands of skis. Please reach out via email if you have any questions about our procedures or stone grinding in general. ([email protected])
