The SDG Thrice OC features an Open Core Zone design that provides vibration absorption while being ergonomically shaped to conform to your palm for enhanced comfort. The grips utilize ramped and undercut grabbers for maximum grip and control, with an ovalized shape that promotes a more natural hand position. These grips are engineered for ultimate comfort and thumb dampening, making them ideal for extended rides. Installation is straightforward with a single lockring system, and the 20A Durometer compound ensures durability and performance.
