I disagree. I would keep it French and use Simplex Super LJ derailers and Rerofriction shifters. They work much better than the Campagnolo NR and the Huret Jubilee. Your bike was probably originally equipped with Mafac Competition brakes and I like them a lot. That's why I have them on three bikes. Campagnolo Nuovo Record and Tipo hubs were optional on the TdF, but there's also Maillard 700, Normandy Luxe Competition and Pelissier. I have some later Mavic 501 hubs on mine and I love 'em.
