Can you get aero without an aero bike? The obvious answer is yes – just tuck your elbows in. But, we're not looking for the obvious answer, we wanted to find out if you could make your bike more aero that it already is without spending any money. All you need, in theory, is the cardboard bike box that your pride and joy may have been delivered in. Plus scissors and tape, of course. We tested the idea in the wind tunnel so that you don't have to.
