Did Shimano Just Leak 13 Speed Wireless?

This week on the GCN Tech Show, we dive deep into Shimano’s latest patents which may have inadvertently leaked details of their next groupset! We discuss the possibility of 13-speed cassettes, a fully wireless system with internal batteries, and even a dynamo hub that could make charging a thing of the past. Plus, we have a packed hot tech section featuring a fully 3D-printed titanium bike, new Pirelli gravel tires, and new rim brake wheels that prove the tech is not dead in 2025.
