Starting in the 2019-2020 race season, for U12 and under age groups, competitors are only allowed to use one pair of skis per race (inspections & competition). Parents, coaches, or technicians are not allowed to furnish additional pairs of skis for use during race day inspections or competition. In addition, at U12 and under competitions application of any type of waxing solution can no longer be applied at competition venues, and the use of ski preparation benches at competition venues is not allowed. Competitors are also being asked not to use fluorinated wax. Finally, the rule makers are recommending that each division hold two races next season that do not allow speed suits showing.
