At Cyfac, we have a long history of making frames for other brands. In fact, the "Cyfac" brand did not appear on a bike until the late 1990's, nearly 20 years after we started building. Whether it was building the house brand for a local Parisian bicycle shop or making the pro frames under the Peugeot, Gitane, MBK, Raleigh, etc brands, we were the actual frame beneath the paint.
This tradition continues, with Cyfac currently building a variety of framesets for various brands. The Caminade line of MTB framesets (see here for more info) is a current project as are the Landscape tandems built for a great UK supplier of beautiful tandem projects.
Bikeradar reviewed the tandem in early 2013. Read the full review here.
