will i have to change belt size or rear pulley size?

curious to know if i change to a 31t front pulley do i have to change belt size or rear pulley at all?or is the front pulley all i need to change?



By installing a 31 tooth front drive pulley lowers your final drive ratio, you should have enough adjustment in your belt to accomodate for the change. If you change your rear sprocket/pulley this will affect your drive ratios as well so if you are to change the rear check to see what effect a different pulley will do.

The calculator below will give you a guide as to what will happen with different Sprockets/Pulleys

here is another calculator to look at if you want to play

They are some great weblinks you have there Dan!

thanks Steve
