It depends on your motor and the track. Racers in the 1/24-1/28 2WD touring/gt class run a 6–14 tooth pinion in most setups, usually on a 53T spur for a final drive ratio near 5.30. Hotter motors (lower turns, higher Kv) take a smaller pinion; tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the One selected.
What is the internal ratio (transmission ratio) of the XBility One?
The One has an internal ratio of 1:1. Final drive ratio = spur ÷ pinion × 1. With the stock 57T spur, a 4T pinion gives an FDR of 14.25 and a 16T gives 3.56.
How many teeth is the stock spur gear on the XBility One?
57 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What springs does the XBility One come with?
The kit springs are Med Black side. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
