[QUOTE=jackbombay;21672174]Less mass in the bike disc than motorcycle or car discs and modified friction coefficient of the pads against the disc when the disc is wet result in the squeal is my hunch.[/QUOTE
I figured the weight was the difference but I hadn't thought of the disc itself.
So they don't perform in the wet it would seem or didn't on that day for some reason.
Did you watch any of the race.
The screeching was horrible I'm surprised they didn't have ear defenders. Cringe worthy.
