Thanks for enlightening the youth and newer to cycling Marco
.
It was a time trial saddle designed to form an aerofoil behind the rider's bum, a wonderful sight was the whole Castorama team using them in a TTT
. Fignon did use one as he rode for them then.
I think the UCI banned them. I don't know how effective they actually were as the wind flow could probably just as easily flow over the rider's back and bet caught by the "bucket" of the seat disturbing the air flow, but no doubt they would have been further developed. Don't worry if you don't like them as they get caught by the UCI fairing rule so you won't see them again
