The engineers at Ceramic Speed have been testing refined versions of their wireless, electronic, shaft-driven shifting system, and they are ready to share the story with the world. Though the Driven transmission is not yet available to consumers, the brand wants to get the word out about the invention they hope will revolutionize the cycling industry.
The Driven transmission consists of a 1×13-speed gear selection, with sets of bearings at the front and rear of the carbon fiber shaft that roll along with the uniquely-shaped cassette and chainring teeth.
