No mistery to gearing the lower the first number the more top end you'll get. The higher the first # the more low end pulling power you have. When they write ratios they leave off the last part of the ratio. That is to say a 4.11 actualy reads 4.11/1. The 2 numbers together are the ratio. Unfortunatly, they make these numbers (gear ratios) to hard to calculate in you head.
To make it more simple to understand in your head, if some one tells you it is a 3.42 round it up or down to the closest whole number. A 3.42 would be a 3 and then put a / and a 1 behind it.
3/1 it means it takes 3 revolutions of the drive shaft for 1 revolution of the wheel. A 3.73 would round to 4/1. So it would take 4 revolutions of the drive shaft to turn the wheel 1 revolution. This is for explanation purpose only. If you do it my way a 3.73 and a 4.11 would be the same thing (4/1) There is a noticable differance between the 2 ratios in reality. Do you see what I am talking about? Or did I just add to the confusion.
