Well better depends on your application. say you have 2 ratios like 3:1 and 4:1. The 3:1 would be a taller gear, because for every 3 turns on the input side you get 1 turn on the out put. the 4:1 is the shorter gear because to get the same speed as the other ratio you have to turn the input more.bluestreak1 said:is it the lower the number the better or higher and whats the significance? is it an indicator of how high your top speed could be?
