Smartly Designed 21 Speed Ceramic Bicycle Drivetrain Will Replace Chains
The Danish company CeramicSpeed join forces with the Mechanical Engineering Department at the University of Colorado, has renewed the humble bicycle with “Driven“, a smartly designed 21-speed drivetrain that uses ceramic plates in the place of chains. This dynamic drivetrain won the prestigious Euro Bike Show Award for 2018.
A revolutionary drivetrain concept that sets new standards in efficiency and eliminates the need for derailleurs and chains. …Driven creates 49% less friction when compared to the market leading chain and derailleur drivetrain. A traditional chain and derailleur drivetrain contains eight points of sliding friction, which is generated from the articulation of the chain at these points. Driven impressively eliminates all eight points of sliding friction.
