So I was assuming that I would need a smaller gear, but it appears I may not. According to Sheldon Browns gear calculator, the Downtube combo of a 48t chainring and 32 max cassette is 2.2 vs my roadbikes 39x30 of 2.6. Does this make sence that the differences in wheels will cause the gearing to be the same??? So it apears that the 48 tooth chainring on a 20 incher acts much like a 39 tooth on a full size bike.
So with the gear ratios very similar will they climb the same up the hill on my commute? (I would just ride the bike up the hill but I haven't bought it yet, but I'm much closer as my car is now posted for sale!!)
