Re: Thanks dyna-ti for the info. I notice that these early 1900's French racers can be picked up for anything between £100 and £1000 and but this particular bike appears to be possibly pre- 1900 with an interesting spec for its time. Fella wants £1250!!! for it plus £200 postage to UK. Seems...

So would a French bike of this age with this type of bottom bracket be special historically? It has a head badge as shown below. Could it be an early velodrome or Tour de France bike? The guy wants alot of money for this bike so I need to be sure. Thanks

Re: According to the owner it has gear changing mechanics inside the crankset or chainset , 3 different positions are available? I too have never seen anything like it. The only thing I have found is that they did experiment on these sort of mechanisms in the very early Tour de France days. Any...

Re: Another picture showing the whole bike.
