When I became interested in the bicycles of the French constructeurs many years ago, the little information that was available came from Japan. I am happy to return the favor: Our book The Golden Age of Handbuilt Bicycles now is available in Japanese. Maybe it will broaden the appreciation of fully integrated cyclotouring bikes beyond the small circle of Japanese bicycle collectors, just like the English version has done in North America.
It would be nice to do a French edition, too, but the French publishing industry is really hard to crack. Today, these wonderful bikes are more appreciated in North America and Japan than their native country.
