Our sizes were specifically chosen to provide a wide spread of of ratio options useful for FRC designers. Larger size VEXpro gears are available so designers can accomplish their entire reduction in a single stage where otherwise they would have used more than one!
All VEXpro gears are 20DP with 14.5 degree pressure angle, and have the same overall width -- this means it is easy to interchange VEXpro gears in your design to change a ratio without modifying the overall system; true versatility.
