Spi Defender Hardweld Runners Yamaha WB-000-642

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.
