This 76 tooth hub gear is a popular choice, when paired with a 20 tooth pinion gear, to create a 3.8:1 ratio between holes spaced 1.5” apart. The 1” bore is surrounded by the Actobotics 1.5” hub pattern which means you can attach the gear to a 1” aluminum, steel or carbon fiber tube using a 1” clamping hub. The hollow center bore of a tube will allow you to route wires, shafting or cables through to create a tidy build.
Tech Tips
