Theoretically 13 / 48 gearing should be equal to a 14 / 49 but is this really the case?

13/48 is equat to about 14/52

1 tooth on the front is worth roughly four teeth on the back.

I did not think it would be 1 to 1 ratio wise but wow I did not realize it would that much difference.

Then again since there are roughly 4 times more teeth on the rear than the front in this case this makes sense.

Did you not do any kind of math in school???

Sometimes things are more obvious than they first appear.

I read always that is 3 more but is more or less

48 divided by 13 is equal to 3.69

52 divided by 14 is equal to 3.71

1 in front equals roughly 2.5 in rear.
