>>1921037Good point, I had not considered the possibility of wearing a dimpled latex outfit. However please let us not degrade the conversation by considering unshaved legs.
On the topic of head hair if one were a cute girl cyclist, one would be wearing a feminine colored aerodynamic helmet to conceal the hair, and of course, the cat ears. Also these sideburn accessories mentioned here

I would tend to concur with your point that a typical casual would settle for binding her breasts inside a constricting latex suit rather than undergoing a masectomy. To ensure adequate flatness, such an outfit would have to be incredibly tight and even with the aid of silicone grease applied pre-race by hand by the older female domestiques; she would be in visible discomfort in front of all the spectators lining the course, writhing in pain with each pedal stroke as her body twists and squirms. She may even let loose the occasional soft whimper or moan, a humiliating spectacle to endure in front of thousands of male viewers, but such is the price to be paid for half measures.
The Koybayashi paper was an interesting analysis indeed. However, I believe it to be inapplicable for several reasons. One, the hair issue that you already brought up (Rabino modeled the hair as a solid in the interests of computational simplicity). Two, the fact that the model was coupled to ground effect which would not apply in a cycling situation. Three, and most importantly, the body was modeled in a fully upright position, not bent forward with a hard saddle pushing with at least some fraction of her 50kg bodyweight against her pubic bone as she gently tilts her pelvis to and fro.
The keyhole strategy involves making a very small incision inside the areola, holding it open with a speculum, and scooping out the excess tissue before sewing it back up leaving a nearly scar-free chest.
