The Spinner Drivetrain

CeramicSpeed Sport A/S
DriveEn is a new and revolutionary 13-speed bicycle drivetrain that sets the benchmark as the world’s most efficient drivetrain. The drive system creates 60% less friction when compared to traditional derailleur drivetrains. Being 99.2% efficient, all power is transferred through ceramic bearing rolling elements. DrivEn exhibits no sliding friction, when compared to a traditional chain drivetrain that includes 8 points of sliding friction where the chain bends back and forth, 2 pulley wheels, plus the frictional effects of cross chaining. DrivEn eliminates all of this. To achieve the ultimate lowest friction, the system uses CeramicSpeed bearings in the pinion spinners and the shaft.
This innovative concept uses plates instead of cogs for the gearing and features a transmission shaft in the drivetrain. All in all, it represents an interesting prototype of a new drive type.
