- The 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.
