Spi WB-000-228 Defender Runners

SPI Code: 228

7/16in. Carbon steel host bar, with a flat top to prevent bar roll during aggressive cornering. Carbides are made of yg13 tungsten that provides the ultimate tensile strength for extreme durability and hardness to reduce chipping and increase longevity. The 90 degree angle of carbide into the pocket of our runners makes for very large cross sections compared to other designs. 1in. Carbide segments allow for flex in ski without compromising carbide adhesion. Engineered and test fitted to precisely fit your ski for easy install. Chamfered ends to reduce catching when backing up and unloading. Extended studs to allow for ski skins. All necessary fastening nyloc nuts included. All carbides and wearbars are finished in black rust preventative. Many competitors use a design that is mounted very shallow in the host bar. Our diamond shaped carbides are set deeper into the host bar giving it more surface contact adhesion. This will make it less susceptible to side impact failure from rocks or gravel. RUNNER STYLE: Defender. Features hardweld on contact area of host bar, giving it more depth to increase longevity. Less damaging to concrete and asphalt surfaces.
