What's the reductions?

What size wheel is it designed for?
Sorry. I meant to post the picture with the 3.25" versa wheel DT so people could see how it mounts.

It is designed for a 3" to a 3.25" wheel. It can work with the 3" colson, and can go faster if the CIM gear is swapped to an 12, 13, or 14 tooth gear.

The overall reductions are 5.45:1 and 13.75:1, which are a little fast for 2 CIMs driving a 3.25" wheel. I plan to add an rs-775 to the gearbox.
