Lewis Hamilton has finally confirmed that his 20-year relationship with helmet supplier Arai has ended and he will now be using Bell.
As Motorsport.com revealed earlier this year, Hamilton began experimenting with Bell helmets earlier this year and had started using them in races.
It came despite having used Arai helmets since his karting days.
Hamilton had said at the time that one of the reasons for evaluating his helmet options now was to optimise aerodynamic performance.
He said: "As a driver you want to improve everywhere, and the [Arai] helmet's not been in the wind tunnel.
"I've had Schuberth trying to get me to try their helmet as well.
"Ultimately you all know I've been with Arai since I was 10-years-old, a long, long, long time, but they don't develop as Schuberth and the others do, and I like that, I like helmets that are developing and improving.
"That doesn't mean that Arai... Arai's still a damn good helmet and I've been with them a long time, and you see me swapping back, because I always go back to the old reliable."
Having kept quiet about the matter in recent races, Hamilton has now formally completed his switch to Bell – after tweeting a picture in Austria.
