Speedo
Its the same mechanical drive that is fitted to the Strada Marvic mag wheel.
The same setup as the later wheel take off, small pressed steel plate and a conventional speedo drive. If your front wheel has no drive there must be a spacer in its place. I suspect its the same drive + steel insert that is fitted to the wheel on the same age 750/900s
Should be easy to find
