Wireless Gear-Shifting Systems in Elite Bikes Exposed to Hacking Risks

Researchers uncover vulnerabilities in Shimano's technology, threatening the integrity and safety of professional cycling races.

Hackers can control and jam gear shifts from up to 10 yards away using off-the-shelf devices.
Vulnerabilities allow attackers to monitor riders' gearing strategies in real-time.
Potential attacks could cause crashes or injuries during high-stakes races like the Tour de France.
Shimano is collaborating with researchers to roll out firmware updates to address these issues.
The study highlights broader concerns about the security of wireless technology in competitive sports.
