I have a 8 speed igh but honestly only use 3 speeds most days, low for hills, normal pace gear and a omg im in downtown pedal faster gear
this is coming from someone in the seemingly hilliest city in America
So which 3 are they? that is gear Ratios as gear inches ..
I added a Schlumpf Mountain drive , a good fit with a 3 speed
54:15. x 16" [1 3/8 tire 349 rim]
High range 77.1; 57.9; 43.4
Low Range 30.8; 23.1; 17.4.. (as if a 21.6t)
Both planetary gears so chain does not shift
And so the 43 to 30 shift can happen bogged down in a climb..
