Recommended Ratios

For the 2nd stage of the drive ratio, a 26T or smaller driven gear provides the required clearance for the module as it rotates. Listed in the table below are some recommended gear sets.

Possible Issues

When creating custom overall drive ratios, the gear set for the 2nd stage must be carefully selected. The driven gear for this stage cannot exceed a 26T tooth count, otherwise the gear will collide with the module spacers and sensor shaft as the wheel module rotates.
