Kink Imprint Sprocket. The Kink Imprint sprocket features a symmetric and balanced design, with a uniquely machined surface pattern. This four spoke design shaves off some weight with two sunken spokes and its four primary cutouts. Accurately shaped and lightly chamfered teeth create a smooth ride and chain seating. Fully CNC machined from 6.35mm thick 7075-T6 aluminum means this is a sprocket built to last.
