The Head Badge on this bike states "Excelsior Cycle Store", and as it was made in Chicago and to my knowledge has lived all of its life here may have been used in 6 day events at the Chicago Stadium, these events were very popular before WWII and again for a short while after the war. The lugged frame is nickel plated, has an adjustable stem in the Major Taylor Style, the period of the Brooks saddle has a very narrow mantle plate that makes for an exceptionally narrow saddle over all, the inch pinch crankset is BSA, the narrow wood racing rims are slightly aerodynamic, and the tires are United States Special Racers 28x1 single tubes. In effect these are similar to a contemporary sew up tire but without the stitching, also the inner tube is not a separate element but part of the casing. Contemporary sew up tires would fit on these rims. This bike is all original.
