Where Bicycles Breathe New Life

About The Carbon Doctor

Fifty years of composites, one small shop in Walworth.

Richard Palmer started working with composite materials in 1972, long before carbon fiber ever touched a bicycle. The progression tells the story on its own: fiberglass racing dinghies, then foam-cored Olympic-class catamarans, then ocean racing yachts skinned in carbon fiber over honeycomb cores — the kind of work where a laminate schedule has to be right the first time because there's no margin for a part that looks fine but isn't. From there his career pushed composite development forward across infrastructure, wind energy, aerospace, and automotive projects, where fiber orientation, resin systems, and mold pressure all had to be understood, not guessed at.

By the time carbon fiber became the default material for high-end bicycle frames, Richard had already spent over three decades thinking about how composite laminates fail and how to rebuild them so they don't fail again. In 2013 he opened The Carbon Doctor in Walworth, Wisconsin, to put that background to work for cyclists whose frames had cracked, crushed, or delaminated — the kind of damage that used to mean an expensive frame went in the trash.
