Yes you read the title right, this revolutionary drivetrain eliminates the need for derailleurs and chains! The award-winning Driven Drivetrain
by CeramicSpeed is poised to radically change bicycling as we know it.
The system features a unique carbon fiber shaft-driven bearing gear
(similar to those used on cars) causing a lot less friction (creates 49%
less friction than chain and derailleur setup, and reduces drag)
leading to a more durable system and resulting in an extremely smooth
movement. This also means that the efficiency jumps through the roof to a
whopping 99%. watch the video below
