It depends on your motor and the track. In the 1/10 2WD truck class, racers gear by final drive ratio: 7.5–8.5T near 10.14, 13.5T near 8.27. On the Ignite Design XT2 '21 Nitro's stock 64T spur that is about 17T for 7.5–8.5T, 21T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Ignite Design XT2 '21 Nitro selected.
What is the internal ratio (transmission ratio) of the XRAY Ignite Design XT2 '21 Nitro?
