Calculating your gear ratio is pretty easy with 2 sprockets (example: 10T to 60T = 6:1 gear ratio), but how do you calculate it with 3 different size sprockets like on a jackshaft? Let's say you go from a 10T on the clutch, 12T on a jackshaft, and then 60T on the axle? How would you figure that out? Math isn't my strong suit...
