6 spreed freewheels are very friction shifting friendly, as the space between the cogs is bigger.
adding cogs has only made the gaps tighter and shifting fussier
Its the ratios not how many 'gears' , happily toured for decades on a 14 -34 t 6 speed freewheel .
Have a folding bike now with 6 speeds ... a 3 speed hub, 2 speed crank with a 150% drop,
54 t ... planetary gear low is like a 21 tooth, (but the chain doesn't move off that chainring)
so the low range uses the 3 speed a second time .. gear range 17-to 78 gear-inch .
