Not to mention it will save on hex bearings, which are notoriously hard to procure for FRC teams. Based on the picture, it cuts a minimum of 9 hex bearings out of the design, and presumably 18 if you were to use round bearings in their place on the idler gears. Using Vex prices, that would also result in over $60 in savings, as well.

There are only two hex bearings outside of the one's in the gearboxes. The rest at circular

This is simply an off-season project to look at the efficiency and feasibility of such a design. Whether or not we use it in the official season is to be seen. The center to center for all the wheels are compatible with .25 chain with no idlers so we will be testing it with chain as well as gears.
