hey PocketRocket

what pully are you using, 20 or 17?

If you are using a 17t pully then your gear ratio will be 7.86 using a 89/24 spur pinion combo.


If you are using a 20t pully then your gear ratio will be 6.68 using a 89/24 spur pinion combo.


If you want i can email you a program that you can use to calculate your gear ratio, just drop me a pm
