Bike rims have gotten deeper (and heavier) all based on the aerodynamic profile of the front of the tire into a tapering rim. I understand that can be much more aero, especially at speed.
Here's my question: After the air comes off the front of the rim, gets whipped up by the spokes, it hits the same aero profile BACKWARDS before moving to the rest of the bike. How does the backward teardrop shape fair in this moving air?
