The biggest component of aero dynamics is not your bike, your wheels, your helmet or hand position…it is your body. It will create the most drag and will slow you down the most. A good bike fit is worth every penny and will bring the most improvements to aero  dynamics and to cutting time off your best bike TT. Book your bike fits with Brendan if you are in Melbourne area and with Shane if you are in Geelong area. You won’t regret it as about 75% of the drag created by air will come from your body
