The first major breakthrough in wear bar technology since the 1950sUnique corner-carving hourglass design yields better control at speed with no increased steering effortBetter tracking on trails hourglass wear bar shape catches snow from ski sides to make steering more positiveAverage of 1' 2' tighter turning radius in soft snow conditions20% lighter than conventional 1/2" diameter round wear barsZinc-plated for corrosion resistanceLifetime wear rate is nearly equal to current round and square wear bar typesManufactured by Stud BoyDesigned and tested by USISold in pairsNOTE: Some models required drilling extra holes in the skis.SHAPER 4.5"41/2" of 60° cutting carbideTwo 11/2" carbide wear padsSHAPER 6"6" of 60° cutting carbideTwo 11/2" carbide wear padsSHAPER 7.5"71/2" of 60° cutting carbideTwo 11/2" carbide wear padsSHAPER 9"9" of 60° cutting carbideTwo 11/2" carbide wear pads
