Demolition Merit Spline-Drive Sprocket
The Demolition Merit Spline Drive chainwheel is CNC machined from 5mm thick 7075 aluminum with multiple cutouts to save weight and a hardened steel insert that's splined for 19mm 48 spline spindles, eliminating the need for a sprocket bolt. Offset 1/8" teeth have a rounded profile to reduce wear while providing better chain alignment.
