Massive jumps in the three speed hub so you have to juggle with the two speed derailleur gear to split the difference, but I am sure you knew that already.No the size of the chain ring is only one part of the equation
The wheel size and the internal hub gears along with the two rear cassette rings all play a part to create the correct number of evenly spaced gears in inches comparable to any other road bike
