ISA was invented by the Swiss bike designer
Andy Muff and patented.
The former elite racing cyclist already built his first frame by
hand in Italy when he was only 21. After the end of his career
in cycling, Muff remained true to the bicycle and worked as an
importer, developer and consultant for various bicycle manu-
facturers and accessories producers in Europe and Asia. Andy
Muff has been developing the sporty-ergonomic road bikes and mountainbikes of his own brand "C2 Concept Cycle" since 2006.
