It depends on your motor and the track. In the 1/10 2WD sprint class, racers gear by final drive ratio: 7.5–8.5T near 8.13. On the VS-2's stock 81T spur that is about 26T for 7.5–8.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the VS-2 selected.
What is the internal ratio (transmission ratio) of the Velocity VS-2?
The VS-2 has an internal ratio of 2.61:1. Final drive ratio = spur ÷ pinion × 2.61. With the stock 81T spur, a 19T pinion gives an FDR of 11.13 and a 32T gives 6.61.
How many teeth is the stock spur gear on the Velocity VS-2?
81 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
