Shimano, a prominent cycling component manufacturer, faces a significant threat as researchers demonstrated that their wireless gear-shifting systems could be hacked. With gear shifters now receiving software updates, the lack of such a patch leaves electronic systems vulnerable. The attack, using simple radio hardware, could result in unexpected gear shifts or jamming, leading to tactical disadvantages or crashes in professional races. This vulnerability can disrupt crucial moments during competitive events such as the Tour de France or the Olympics, potentially altering outcomes and costing teams victories. The impact extends to the credibility of the sport and Shimano's reputation as a trusted equipment provider.
