I believe one of these has fractured on test, but it is a point which can be easily strengthened. Regarding the inner brake, I am a little bit doubtful whether the aluminium and ferodo combination can be used for this, but it might be tested. (5) ROAD WHEELS. X.3476. X.1258/4. The Dunlop pattern of road wheel hub is very complicated and rather heavy. The wire wheels too have also been somewhat troublesome through broken spokes. I am of the opinion that the Rudge-Whitworth wheel may be considered as simpler and less likely to be wrongly constructed through errors of dimensions. Records of the behaviour of this type of wheel during the War should be found with a view of adopting it instead of the Dunlop pattern. X.3482. As an alternative, I strongly recommend that we at once design a hub to carry the Michelin disc wheels, which I understand have done so well in France during the War, which are so clean and simple, convenient for twin tyres, and also are beneficial to the tyres, in as much as they do not run so hot. This type of wheel would probably meet favour with the Paris people and with Count Salamanca. The only point I am not sure about is whether they entail extra weight, but I think when the double hub is weighed with the wire wheel, the disc wheel will not be very much heavier.
