Try our gear ratio and rollout calculator to find the right pinion and spur for your car, whether it's Team Associated, Tamiya, Traxxas, or any other make. Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur.
30 mar 2021 · You can set the transmission ratio to 1:1 value, calculate the ratio based on transmission gear sizes or manually enter the ratio if it is already known. It is presumed that the transmission consists of 3 gears.

1 sty 2004 · Simply stated, a gear ratio is a numerical value that describes the relationship between two gears (a spur and pinion gear for our discussion). A gear ratio can also describe the relationship between the FIRST gear and the LAST gear in a gear train (or a transmission).
Understanding your vehicle’s gear ratio is a powerful tool when making changes at the track or around the backyard. Whether you’re aiming for longer run times or to set a land speed record against your friends, knowing what to change and busting out some simple math makes it easy to see how gearing works.
For the same rim width, 650b is lighter and stronger. 650b rim diameter is 38 mm less than a 700c rim (584mm vs 622mm) so unless you're running much fatter tyres on your 650b (which is fashionable but stupid in my opinion, and adds unnecessary weight) the gearing on 650b rims will be about 6% lower.
Calculate your ratio, your final drive ratio (FDR), and rollout, and see exactly how much of a difference a gear change will make.
