Jean-Pierre Ryffranck was born in Eeklo, Belgium. He moved to Montreal in 1955. By trade, he was a tool & die maker, a machinist, and a welder.
He was very interested in cycling. During the 1970s he started reading about how to braze frames. For his first frame, he drove to Vermont to buy a Reynolds 531 tubeset from Bill Vetter, who was a small builder. After it was complete, he showed it to Bill, who was blown away; he couldn’t believe J-P made it himself. It took him 2 years to build the 1st frame, because he made all his fixtures and jigs himself, along with some of his taps and dies.
Ryffranck moved to Sherbrook, Quebec, and started building frames as a hobby. He began selling them in 1984, as a side job. At age 58 he left his tool making job to pursue framebuilding full time, which he did out of his garage. With his background as a master tool maker, he was known for his precision; it would take him approximately 30 hours to build a frameset.
