In this episode of Cycling Over Sixty, host Tom Butler starts by discussing the results of an unintentional experiment with virtual cycling. He is then joined by mechanical engineer and cycling enthusiast Garren Miler to examine the history and mechanics of non-circular chainrings. They discuss the development and decline of oval chainrings, including the Biopace design. This technical discussion leads Tom to make an unconventional decision about his own ride. The episode offers insights into cycling history and technology that may inform future cycling upgrades.
