Trying to figure out which speedo gear is needed for the above combo. This is to make the speedo work correctly. Im not sure what gear it has now. But maybe one of you guys knows the right one for the combo. Thanks.

BTW be careful of the color coding. Count the teeth.

I use a 32 tooth with 27.5" tires.

I know it has a white gear in it now. But had 3:91 prior to me putting in the 3:23 gears. I pretty sure that was not even correct beaing as though its a 27 tooth.

The new wheels are 15 inch but overall height i have not measured.
