It depends on your motor and the track. In the 1/10 2WD f1 class, racers gear by final drive ratio: 21.5T and up near 2.19. On the ICON 2's stock 60T spur that is about 27T for 21.5T and up. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the ICON 2 selected.
What is the internal ratio (transmission ratio) of the Schumacher ICON 2?
The ICON 2 has an internal ratio of 1:1. Final drive ratio = spur ÷ pinion × 1. With the stock 60T spur, a 26T pinion gives an FDR of 2.31 and a 47T gives 1.28.
How many teeth is the stock spur gear on the Schumacher ICON 2?
60 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
Kit setup

What springs does the Schumacher ICON 2 come with?
The kit springs are Gold (#U7889) front, Black (#U4838) side. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
