Uli Fahl could actually have retired at the beginning of the nineties. Back then, his AC titanium quick-release clamps were launched into space on board the Russian space station MIR and fixed folding tables and chairs. Fahl had achieved his goal: weightless bicycle parts.
But because the scales down on the green planet continued to show values, Fahl had to go back to the drawing board for better or worse. Over the last 30 years or so, he has created all kinds of lightweight products. Seat posts, stems, cranks or saddles - there is hardly a part that Fahl has not subjected to a radical diet. Tune's hobbyhorse, however, are hubs and wheels. Because no other component on a bicycle has a greater influence on acceleration and riding behaviour, the round wheels are a particular focus of weight reduction. We took a look at the production of a Tune impellers from milling the hubs to spoking by hand in Buggingen. But see for yourself.
