CeramicSpeed Chainless Drivetrain
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
