# Thread: 26/29 inch Gearing

1. ## 26/29 inch Gearing

Are the ratios about the same on 26 and 29 inch tires as long as your working off the final drive #

Example 32/18 x 26 inches=46.2
32/20 x 29 inches=46.4

Is this a good way to figure this?

2. Yup. Add two teeth in the back to your 29er for the rough equivalent.

3. ## yes

cept someone said that 26 is really ~26.5. close enough. for my KM i use 32/18 and 34/20 which is slightly easier.

with some of the new 29" tires 29 may now be creeping up on 29.5 so who knows. experiment. just figure a 29/26 conversion factor. that will be accurate enough.

Every model tire has a different actual diameter. Can not really make any generalizations.

You can download the Excel gear inch calculator from my site. Look on the "Tech" page.
