I dont remember the name of it, but in the 90s there was a front "wheel" with no hub, no spokes, just a carbon "rim" that was co-moulded to the fork and steerer, and presumably bearings between the carbon rim and another rim on its outside which held a tire.
if i could only find a picture!! anyway, some older guys might remember it. it looked like a donut on the front of your bike, and it looked identical spinning and staying still
current most ridiculous is the blackwell research airfoil front hub.
those trigger seat posts that shot the saddle forward a few inches with the flick of a remote switch for power on the flats, and back again for climbs... they were crazy too. There was also a tri bike, maybe named a fox (not the corima) which only had brake levers at the ends of aero bars.
todays gizmos are (IMO) nothing compared to old stuff.
