Kink Bmx Imprint BMX SprocketThe 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. SPECIFICATIONS SIZES 25t, 28t MATERIAL 7075 T6 Aluminum THICKNESS
