Le Chemineau road bike

Le Chemineau, as seen at a recent bicycle swap meet. Incorrect wheels.

 Early attempt at index shifting.

 The headbadge is a reproduction on the kilometer marker at the town of St. Etienne.

 Seat tube oiler is located behind the seattube. The Simplex front derailleur is not properly set up, as one can see. There is a cork inserted into the seattube from the bottom bracket shell, and the rider would pour oil into the seattube, from the seatpost, and when he swiveled the oiler down, it will oil his chain. It seemed needed on the early derailleur systems on the dusty, unpaved roads of Europe post-war. I have seen this feature on French and Italian bicycles.

 Maxiplume aluminum cottered crankset, with what appears to be Cyclo Rosa chainrings.

 Chemineau proprietary rear derailleur. It is similar to the Cyclo. Oscar Egg dropouts.

 Henri Gauthier leather saddle. This is the steel rail model, but they also produced an aluminum rail version much like the Ideale.

Lam Super Dural aluminum brakes.

Barra aluminum bicycle

Beautiful Barra aluminum bicycle.
Nichola Barra build these aluminum bicycles from the late 1930s into the 1950s.
it is gas welded aluminum, expertly done, flawless, and way ahead of its time.
Also take note of the ovalized tubing at the joints- Seatlug and bottom bracket.
This example was equipped Lam brakes, Le Chat front derailleur, Stronglight 34 cranks, Simplex rear derailleur, Porteur Hubs, Simplex Skewers, Stronglight Headset, Ideale saddle.
These bikes are exceedingly rare, and to see one in person is extremely hard to do, expecially here in the United States.

Ken Denny in Boston owns this bicycle.
