Ugly, gigantic helmets are old news in speed skiing.
No idea. I'm going to guess yes but... The wheel is already punching the hole but is there drag induced when the air flows break around the wheel and then is split again by the downtube? Is an airfoil downtube more useful? Never looked at the science have to confess.Talking of amateurs having a go, how do you feel about the front wheel to downtube spacing?
Is it actually aero to minimise that gap?
Never logged at the science have to confess.

Don't forget the Stokes condition - actual boundary layer is at the same velocity as the surface. So, in the frame's reference frame we have an airstream with both forwards and rotary momentum that encounters the downtube.
