The next step in the evolution of the classic drivetrain.
Based in Holstebro, Denmark, CeramicSpeed is a company built on innovation. In the early 2000s, the brand began producing ceramic bearings for both sport and industrial applications. While using technology developed by NASA in the ‘90s, the company provided a better solution to replace traditional steel bearings. These top-grade silicon nitride ceramic balls were not only 58% lighter that steel versions, but they also provided 30-50% extra speed. Fast forward to 2018, and CeramicSpeed shakes the industry gain by introducing a revolutionary product in the world of cycling. Created in a collaboration between the Danish company and the Mechanical Engineering Department at the University of Colorado, Driven is the next evolutionary step in the history of the drivetrain. It ushers in the era of a bicycle without chain or derailleur.
The innovative drive shaft system features 21 ceramic bearings to enhance efficiency and speed. Designed as the world’s most efficient drivetrain, Driven reduces friction by an impressive 49%. Driven transfers torque from the front ring through the pinion style drive shaft and finally to the 13-speed rear cog. This ingenious design removes all eight points of friction present in classic drivetrains. Thus, it effectively offers the solution for a bicycle without chain and derailleur. The Driven prototype has received the prestigious Eurobike Award at this year’s Eurobike Show, which took place between 8-10 July, 2018. Photographs© CeramicSpeed.
