he first major breakthrough in wear bar technology since the 1950s
Unique corner-carving hourglass design yields better control at speed with no increased steering effort
Better tracking on trails - hourglass wear bar shape catches snow from ski sides to make steering more positive
Average of 1' - 2' tighter turning radius in soft snow conditions
20% lighter than conventional 1/2" diameter round wear bars
Zinc-plated for corrosion resistance
Lifetime wear rate is nearly equal to current round and square wear bar types
Manufactured by Stud Boy
Designed and tested by USI
Some models require drilling extra holes in the skis.
