To build upon this point, it's pretty easy to vary your drops/tread profile by adjusting your pulley size. Since the torque is transmitted via the tread, you (likely) don't particularly care about the axle rotation speed. This allows you to use different size pulleys (sprockets, in this case). If all your axles are mounted at the same distance from the bottom of your frame, a larger pulley in the middle would result in a "drop center" in your tread.
