Hello everybody,
I am building a 70s velosolex bicycle and i am thinking of replacing various parts. I found online a shimano ULTEGRA 6600 crankset and i don't know whether to buy it or not.(The price tag is 65 euros fotos below)I am also looking for shimano 105 v brakes-cassette-front and back shifters.
