Same bike, different wheel OD?
My odd ball 1940s Rudge roadster has caused some head scratching. The rear wheel is an ISO 635 (Dutch bike tire size) and the front is 622/700c. Was this ever a thing? I’m guessing the front(?) was replaced at some point?
Another oddity. The hardware is metric. It’s a Canadian market bike so maybe that makes a difference? The whole thing is bizarre.
Anyone have any insight on this?
Pic since that is obligatory…

In Canada, during this era, the "standard" rim size was Canadian 28" x 1-1/2" which is 622mm BSD, the same as 700C. I have seen UK market catalogues for Rudge from 1939 and a circa 1950 catalogue, neither of which show camelback style frames. Consequently, there's a good probability that your bicycle was built specifically for the Canadian market and that the front wheel is correct.

You mean French bikes aren't the only head scratchers? Ha...
I am impressed with the Fork Rake.

The metric thing really boggles my mind unless a diehard Québécois had an act of rebellion rethreading bicycle parts.

Another thought about the mismatched wheels. Post WWII production making do with what they could get?

The rake is probably the reason I bought the ridiculous thing. The rubber Dunlop saddle is icing on the cake.

The wheel was replaced and the hardware should be Raleigh 26 tpi thread. Not metric. Cool roadster.
Oh and beware the Dunlop seats...they'll stain any arse that sits on them.
