He didn't "brag" about anything. He said that if he had one advantage, it would be the disc brakes but he gave himself 10% chance at most to win it.I hope the gusts of wind aren't becoming too dangerous (riding a disc with sidewind on a 100K/hr downhill isn't really comforting!).
Campenaerts' crash however was purely about braking enough before the corner.
He bragged before the TT that his bike had disc wheels and thus he could brake faster than Ganna on rim brakes (and thus would gain some seconds in the hairpins).
That backfired quickly.
