Aerodynamics / Aerodynamic Cost / Aero parts

Here's another estimate:

"It is estimated a close fitting skinsuit can save 3.2% of your total energy. [1] This equates to 29 seconds in a 40 km time Trial."

Well I was thinking for a 24 hour ride. So pretty slow negating a lot of the aero effect. But for a very long time so possibly still Worth while.

Too late now anyway.
