Spur/pinion x internal gear ratio (ta04's is 2.133)

The internal gear ratio is the ratio of the pulley teeth(big/small)

# of Spur Gear teeth ~ # of Pinion teeth x Transmission Ratio = Final Drive Ratio (FDR).

If you are running Foam tires, some people like to calculate rollout also. Otherwise with Rubber tires the FDR is all you need.
