46 t CDX sprocket, on a Speed Drive crank, will act like a 76t
with the 22t freewheel 1 gear will be 2.09:1, the other 3.45:1 (gear 1 x 1.65)
20" wheel .. 40.8gi ; 69gi
a pretty simple 2 speed .. though the Swiss-German Made planetary crank is a bit spendy ..
they went down a bit moving production out of the CHF to the Euro zone.
