Wear Bars (skags)
Wear bars are replaceable steel rods under the skis. They are essential for steering. Without them, you’ll slide off the trail when turning corners. Wear bars should be inspected often, and replaced to reduce the chances of a crash and to prevent damage to the skis caused by abrasive surfaces. Be aware that carbide steel wear bars can carve grooves in pavement, so be careful when riding across private driveways and roadways since extensive damage can be caused over the course of a season.
