+Cristo Nabarrete : the gear you need is determined by two factors. You
axle gearing and tire size. The chart at the end of the video should help
but you’ll need to know what gears you run in your axles. They should be
3.07, 3.73, or 4.10 unless they were regeared.
I have 35s and for now Im stuck with 3.55 gearing from my swapped in axles
till I can afford a regear. Thats not on the chart but Im guessing 27 tooth
or about there?
Thanks!
