1954 Rotrax Concours

Just sharing the recent Rotrax find. Serial number begins with "54", dating it to that year. All appearances are that it is the "Concours" model at or near the top of the range. Lots of pics.


Full bike.

Very cool seatstay cap.

Looks like the chrome perhaps has a lacquer clearcoat that's oxidizing.

Paint is peeling up from the chrome in several places.

This bike has seen a lot of love on a thread scozim started. Great that you bought it. If that bike had been located 2k miles closer to the Midwest near where I live, I would have raced you to have picked up that bike.

mismatched rims

double cable housing stop. Desodromic?

Nice bike!
I suspect that the double cable stop on the chainstay is not for a desmodromic derailleur, but rather for the Simplex Juy 543 or Juy 51 which used a cable which split just before the cable stop. One cable controlled the throw: The other cable increased the spring tension when shifting from a larger cog to a smaller one.
