Unless its two drive trains for going X and Y, you might want to get out the drill.

I warned everyone about it, but they went with the 14 inch wheels. In order to support those 14 inch wheels, one of our mentors had to make a brace for the sprocket. In order to chain them up, 4 big metal plates are required for the gearboxes. It is slow, sluggish and cumbersome. It was designed to to over the bump, but it flips over.
