Driven – A farewell to derailleurs and chain

CeramicSpeed bring you Driven

– a revolutionary drivetrain concept that sets new standards in efficiency and eliminates the need for derailleurs and chains

CeramicSpeed have raised the bar once again when it comes to drivetrain efficiency.  This time with a revolutionary drivetrain concept that 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 have created a drive shaft concept that utilises 21 CeramicSpeed Bearings and 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. A traditional chain and derailleur drivetrain contains eight points of sliding friction, which is generated from the articulation of the chain at these points. CeramicSpeed’s new Driven concept impressively eliminates all eight points of sliding friction.

Bearing Driven

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

 

At the head of CeramicSpeed’s Driven Project is company Chief Technology Officer and founder of Friction Facts, Jason Smith.

CeramicSpeed has proudly accomplished what many have said couldn’t be done. We’ve achieved a 99% efficient multi-speed drivetrain while eliminating the chain and complex rear derailleur. Advancements in drivetrain technology have been evolutionary since the 1920’s.  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.

Acknowledging its level of innovation, the EUROBIKE Award jury has chosen Driven as one of the winners of this year’s edition, amongst 366 entries. The original Driven prototype was displayed at CeramicSpeed’s Eurobike stand B3-205 from 8th to 10th July. The award-winning concept bike is on display in Foyer West in a special AWARD exhibition throughout the EUROBIKE show.

In our eyes this is the Innovation shown at Eurobike 2018. We look forward to Ceramicspeed getting it production ready.
