Not sure if this has been mentioned on here before, but there is a cheap and easy way to save a bit of aero power by filling the area between your tyre and your rim.
As has been shown by several different studies, bulbous tyres (i.e that exceed the width of the rim) are generally to be avoided as they make the oncoming air detach and become turbulent over the rim.
Anything that can smooth the transition from tyre to rim is of benefit, and this is why Mavic created the CX01 blades, specifically to fill this gap.
But if you'd rather not shell out thousands on a new, full Mavic wheelset, you can do it on the cheap!
The video below shows how to use silicone to fill the gap and create a smoother interface.
This may not get you on the next podium, but it may save you a watt or two!
