Lewis Hamilton has reacted to Red Bull’s controversial device that alters the height of its front bib ahead of the United States Grand Prix this weekend. Rival teams had grown concerned that Red Bull may be exploiting parc ferme rules by utilising a way to lift and lower the height of its T-tray between qualifying and race day.

The ride adjustment device used by Red Bull explained as how it works to make a difference to the car's operation during qualifying and race.

Lewis Hamilton has applauded Red Bull's innovation although he does wonder if their winning period has now stopped.
