I'm setting up a street scrambler for gravel roads. Does anyone know how to make this conversion. Front sprocket number of teeth , offset or not ? Rear sprocket ?

 

Easier and cheaper just to have a spare belt. Chains can get destroyed in rocks also. Nothing magical about them at all.

 

Thanks Ih 4x4. I am changing wheels to wire spokes and was wondering what options I had. Staying with a belt is sure simpler.
