About the Mod 0.5 Spur Gear
Lightweight & Race-Ready Design
Precision-machined from durable Delrin, this spur gear system weighs only 2.7 grams, significantly lighter than the stock setup at 4.3 grams. The wider 4.5mm tooth profile increases gear strength and longevity under the stress of high-output motors. Installation is straightforward; simply remove all stock slipper components, slide the Exotek gear in place over the pin, and secure it using the stock three-millimeter locknut.
