SPI Ripper Four/75 Carbide Runners Black For Yamaha

Description

The SPI Ripper Four/75 Carbide Runners are designed for Yamaha skis, featuring a 7/16in. carbon steel host bar with a flat top to prevent bar roll during aggressive cornering. The carbides are made of yg13 tungsten for extreme durability and hardness, reducing chipping and improving longevity. The 90-degree carbide angle ensures a large cross-section for enhanced adhesion, while 1in. carbide segments allow for flexibility without compromising adhesion. Chamfered ends reduce catching during backing up or unloading, and extended studs allow compatibility with ski skins. These runners are engineered for precise fit and easy installation, with included nyloc nuts for fastening. The black rust preventative finish ensures durability. Featuring 4in. of 75-degree tungsten carbide, this design is less aggressive, offers a longer wear period, and is recommended for use with lightly studded tracks or no studs.
