SHS CNC Gen. 3 12:1 Super High Speed Gear Set M4 This version is equipped withDescription: SHS CNC Gen. 3 12: 1 Super High Speed Gear Set This is a 12: 1 gear set made by SHS, these recently introduced 12: 1 sets are just slightly faster that the 13: 1 sets. For comparison stock gear sets are around 18: 1. For some reason many manufacturers don't actually label the ratio, but rather use code names. Most manufacturers "high speed" gear sets are 16: 1, so this set is much faster than that.
