Use the formula:
Spur x 1.83 / Pinion = Ratio
Atention I bought a PRS adaptor and it is not a straight fit. You must trim the lenght of those six plastic knobs that engage on the adaptor, and you must trim the width of the adaptor itself. Otherwise it will be stressed and will not allow a free spinning.
