The title can not explain it more specifically, however, recently I watched a video where I guy explains a calculation and tells the result gives how easily you climb ramps. Here is the calculation:
Rear cassette: Biggest sprocket size / smallest sprocket size Crank cassette: Biggest sprocket size / smallest sprocket size
You multiply the end results and multiply it again with 100 which gives you a percentage.
Here is an example:
Say I have a front cassette 22-32-44 and a rear cassette 11-36. The calculation is as follows:
(44/22)*(36/11)*100 = %654
So the guy says the bigger this number, the easier you climb ramps? That doesn't make ay sense to me. Does it hold any truth or does he try to mean something else?
