| c.1900's early, Brennabor Bicycles, Gear Calculator (Original) (013) |
|---|
|
| This is not a catalog; it is a inch and meter gear calculating mechanism produced for the German bicycle manufacturer
'Brennabor', established in 1871. You turn the dial to the desired cog size and chainring size; the mechanism gives you the inch-gear and meter-gear. It is printed on heavy card stock to which the dial is riveted. It was most likely produced for France, Belgium or Switzerland because some of the language on the card is in French. The condition is very good; the only blemish is a small nick on this side near the seat tube, slightly above the chainring. The dimensions are 5 1/2 x 3 7/8 inches, photo #032.
