In order to convert the Bertin to a 650B I exchanged the Mafac Racer brakes for a set of long reach Lam sidepulls of the same type that work very well on my 650B porteur. As it turns out, the large, stiff springs on these brakes are nearly impossible to operate with road brake levers. Neither the CLB's that were on the bike already or the Mafacs that I tried were up to the task, so I've installed the guidonet levers that were on my Urago instead. These levers are perfectly matched to the brakes and are easy to operate with good modulation. An additional bonus of the levers is to streamline the top of a bike that has a lot going on visually as it is. Now for those British fenders...
