There was early friction between Wolhauser and his supplier Clerc. Wolhauser wanted to have exclusivity but it was not really acceptable to Clerc. He accepted that Clerc wanted to brand his own bicycles and make a name for himself, where else could he have found dural frames of this quality and level of finish?
After purchasing dural frames for a few years from WOLHAUSER, a bicycle dealer from Geneva, VIFIAN, and one from Montluçon, CALMUS, started to purchase directly from CLERC, this caused a rift between Clerc and WOLHAUSER. Raymond Clerc sold most of his production directly under his own brand after this point.
