CeramicSpeed are aiming to shake up the cycling component world with its new Driven drivetrain. The truly revolutionary concept eliminates the need for both front and rear derailleurs as well as the chain. Partnering with the Mechanical Engineering Department at the University of Colorado, CeramicSpeed has created a drive shaft concept that they say sets a new benchmark as the world’s most efficient drivetrain.

Driven creates 49% less friction when compared to the market leading chain and derailleur drivetrain, claims CeramicSpeed. A traditional chain and derailleur drivetrain contain eight points of sliding friction, which is generated from the articulation of the chain at these points. CeramicSpeed’s new Driven concept eliminates all eight points of sliding friction.

To achieve that level of performance, Driven uses CeramicSpeed Bearings in a pinion style drive shaft system. In total 21 CeramicSpeed Bearings play a role in the functionality and efficiency of Driven. Thanks to their low rolling friction and longevity, the bearings transfer torque from the front ring through the drive shaft, then onto the 13-speed rear cog.

“CeramicSpeed has proudly accomplished what many have said couldn’t be done. We achieved a 99% efficient multi-speed drivetrain while eliminating the chain and complex rear derailleur,” boasted CeramicSpeed’s Chief Technology Officer and founder of Friction Facts, Jason Smith. “Advancements in drivetrain technology have been evolutionary since the 1920s. Driven is truly revolutionary given its unique rolling element power transfer and unmatched efficiency. The Driven concept has the ability to change the way the cycling industry views drivetrain design and drivetrain efficiency.”
