When I bought it I didn't really know what I was getting and just took the advice of the shop. On steep hills I invariably had to get out of the saddle to get up them. With my next bike I got a triple chainset and wide spread of gears. If I went up a climb of 20% and above I would invariably be hitting Maximum Heart Rate, whether I was spinning a gear or standing out of the saddle, so the idea of easier gears seems a bit of a nonsense. The terrain may be easier or you may find things to be easier by virtue of better fitness, but easy gears no such thing.
An easier gear is very simply one that requires less force to push. At 60rpm or 70rpm or whatever for a given gear you will be going a given speed.
As I understand it there is some sort of range of cadence that is efficient, so for example a very hard gear at a very low cadence would is simply inferior to an easier gear at a more normal cadence.
You have to be making a reasonable power to make 90 rpms Cadence worthwhile. It’s thought to be about 120 Watts. At that power, at 90 rpms, the fast twitch muscles are engaged in such a way, that they are fuelling most efficiently.
