How do the participants at the IOM TT scrub in their tyres ?
One "on bike video" I saw, shows the rider taking it easy for the first 5 minutes or so, but his "taking it easy" was hammering down Bray Hill and beyond at what must have been over 100mph with the familiar TT bike lean angles.
I think they rub then with aviation fuel and this removes the wax ... plus they don't seem to care as they have huge balls
