Here they are being used on a Selbach bike in a Frome Wheelers/Trowbridge CC inter-team time-trial

C.Harrell in a 1957 Inter Club 25. Frome Wheelers & Trowbridge CC. Note the rare quick release mechanisms, as kids we called these Selbachs as they always seemed to be fitted to his frames. (image and details - Mick Butler)


Mark Stevens also has a pair of these wheel fasteners - made in France, believed in the 1930's
