I have the impression that the most suitable wire wheel that we have under consideration is the Dunlop, and I think that, when they make the conical seating for the wheel slower ~~that~~ there will be very little trouble with them providing that they are thoroughly well tightened on the hubs. I do not think the Riley wheel is quite so good a job or so neat as the older Rudge-Whitworth. With reference to the new Rudge-Whitworth wheel, I have stated that I have little faith in a wheel that has no locking device whatever, and I believe that their new scheme of automatic locking will [*as Mr Nadin states*] introduce a great deal of friction which would prevent the ordinary tightening being performed, It seems to me that the*s* ~~any~~ fault ~~of the~~ wheel would not be so serious a matter if the wheels will tighten themselves up automatically, (which I ~~much~~ doubt) but at the same time [*it suggests*] I ~~feel~~ sure that it might be very difficult to remove such a wheel if it did tighten itself up tightly automatically. I, therefore, recommend as I did some time ago that we get a large number of Dunlop wire wheels with a [HANDWRITTEN IN MARGIN] Communicate this to W.
