Ferrari F2001 wheel hub used at Imola GP 2001, because of which it had to pull back. Michael Schumacher got back to the boxes at lap 23 with the front wheel deflated. He restarted the engine but the team saw that the rim was damaged because of a bad component and had to stop Schumacher’s race. The problem concerned the suspension group formed by the hub, the brakes and the air intakes.
